> When a law firm should look for a Nitro PDF OCR alternative: what Nitro's OCR does by platform, what a converter cannot replace, and how to run both.

Look for a Nitro PDF OCR alternative when the result you need from a scan is data instead of a PDF, when people without a Nitro licence need the text, or when a Windows-only licence no longer matches the computers in the office. For redaction, Bates numbers and edits to the page itself, keep Nitro.

"Needs more" in this post means more kinds of output and more people able to get it. It does not mean better recognition, and nothing below ranks one product's reading of a page above another's. Every statement about Nitro comes from Nitro's own user guides and web pages, opened on October 8, 2026.

## What does Nitro PDF's OCR do, in Nitro's own words?

Nitro says its OCR "converts scanned documents and image-based PDFs into searchable, editable text by creating a hidden text layer behind the scanned image". It can run when you open a scanned PDF, on pages you pick, or across many files in a batch.

That sentence is from Nitro's page on [OCR software for PDFs](https://www.gonitro.com/ocr). The user guide fills in how it works on Windows.

### Two output modes

The Windows guide to [OCR in Nitro PDF Pro](https://www.gonitro.com/user-guide/pro/article/optical-character-recognition) gives a choice each time you run it:

| Mode | What Nitro says it enables |
| --- | --- |
| Make Searchable | Text selection and markup |
| Make Searchable and Editable | Text selection, markup and editing |

The first leaves the scanned page as a picture with text behind it. The second lets you change the words on the page. For a document whose appearance matters, such as a signed exhibit, the first mode is the one that leaves what you see alone.

### Three ways it starts

- **A prompt on opening.** Nitro says that when you open a scanned PDF, the program may offer three buttons: Cancel, OCR Page and OCR Document.
- **The OCR button.** On the Review tab, in the Document group. An Options button selects a page range.
- **Selected pages.** The guide to [running OCR on an existing PDF](https://www.gonitro.com/user-guide/pro/article/ocr-an-existing-pdf) describes right-clicking pages in the Pages pane and choosing OCR Pages.

### The settings Nitro exposes

Nitro's article on [OCR preferences](https://www.gonitro.com/user-guide/pro/article/ocr-preferences) says recognition is provided by an I.R.I.S. OCR plugin integrated into the program, and lists what you can adjust: skew correction, text orientation detection, a fixed threshold for separating text from background, colour smoothing, language, a quality level of Low, Medium or High, and downsampling and compression of the page images afterwards. Nitro's OCR page adds that the engine includes dictionaries for legal and medical terms.

### What Nitro tells you to expect

The Windows guide ends with two notes: OCR accuracy depends on document quality, and some recognition errors may need manual correction. Its [OCR troubleshooting tips](https://www.gonitro.com/user-guide/pro/article/troubleshoot-ocr) recommend scanning at 300 dpi or better, in grayscale or black and white, with the page kept straight. That advice holds for any OCR tool, and the post on [the best DPI for OCR](https://www.schemalaw.com/blog/best-dpi-for-ocr) explains the reasoning.

## Why would a firm want a Nitro PDF OCR alternative?

A firm may want one for a reason outside recognition itself: a three-year licence is coming up for renewal, the office has added Macs, more people need text than hold licences, or the work now ends in a spreadsheet or a data file. Each reason points to a different remedy.

**A renewal date is forcing the question.** Nitro's guide to [choosing a Nitro PDF plan](https://www.gonitro.com/resources/choosing-the-right-pdf-plan-a-guide-to-nitros-flexible-options) describes Nitro PDF Classic as a three-year Windows desktop licence paid once, and says the licence expires after three years and requires renewal. Nitro PDF Standard and Plus are subscriptions. A firm reaching the end of a Classic term has to choose again anyway, which is the natural moment to ask what it actually uses.

**The office is no longer all Windows.** The same guide says Classic is Windows-only, and that Standard and Plus support Mac, iOS and web access. If two new associates arrive with MacBooks, the Classic licences do not cover them.

**Occasional users.** A per-user plan suits people who open the editor daily. It suits a partner who wants one scanned letter as text twice a month less well. The arithmetic for weighing per-user pricing against per-page pricing is in the post on [OCR cost per page](https://www.schemalaw.com/blog/ocr-cost-per-page).

**The deliverable is rows or fields.** Nitro's recognition adds text to a PDF. A paralegal building a medical chronology or a payment history wants the scan's tables as spreadsheet rows, and a firm feeding its own database wants JSON or CSV. That is conversion work, with the PDF left behind.

**Fewer decisions per file.** Nitro's preferences give a trained user control over recognition. They also mean that two people with different settings can get different text from the same page. A firm may prefer one fixed routine to per-user settings.

**Keeping the received file out of an editor.** Recognition inside an editor changes the file it is run on. Nitro's Mac guide says of batch OCR that each document "saves back to its original file". A firm that wants the scan as received to stay unchanged may prefer a routine in which a copy goes to a separate tool and the export comes back as a new file.

None of these says Nitro reads pages poorly. If your only complaint is the text on bad scans, try Nitro's own quality setting and scanning advice first, then test the same pages in a second tool before drawing a conclusion.

On the file you get back, look up a clinic name and a visit date inside the medical record, then the invoice total and the exhibit number. Also search a discovery PDF for its pleading caption. Read what you find on the page picture before you copy dates into a chronology.

## Does Nitro's OCR differ between Windows, Mac and the web?

Yes, by Nitro's own documentation. The Windows and Mac guides describe different menus and different extras, and the guide for Nitro's web workspace lists other document tools and no OCR tool. Which plan you hold also decides which platforms you can use at all.

| | Windows guide | Mac guide | Workspace (web) guide |
| --- | --- | --- | --- |
| Run OCR on a document | Review tab, OCR button | No single-document article. The Mac guide's OCR & Scans category covers batch OCR, the OCR layer, OCR text and scan adjustment | No OCR article in the guide as read for this post |
| Many files | File, then Batch Processing | File, then OCR Files | Not described |
| See or edit the hidden text | Not described in the articles read | View the OCR layer, edit it word by word, clear it | Not described |
| Page clean-up | Skew, orientation and threshold preferences | Rotate and deskew, resample, adjust image | Not described |
| Related tools | Batch sequences | Batch runs in the background | Smart Redact, Table Extract, Form Extract |

### Windows

Besides the OCR button, Nitro's guide to [batch process tools](https://www.gonitro.com/user-guide/pro/article/batch-processing) says the Batch Processing tool can "run OCR on many image-based PDF files to make their text fully searchable", and that you can chain actions into a custom sequence.

### Mac

The Mac guide has its own articles. [Batch OCR on the Mac](https://www.gonitro.com/user-guide/mac/article/batch-ocr) is under File, then OCR Files: you add documents, click Perform OCR, and the files are processed in the background while a coloured indicator shows success or failure for each. The article labels this an advanced feature of Nitro PDF Pro.

The Mac version also lets you look at the hidden text. Nitro's article on [viewing or removing the OCR layer](https://www.gonitro.com/user-guide/mac/article/viewing-and-removing-the-ocr-layer) says the recognized text is "a close, but not perfect, rendering" of the page and that you will need to proofread it. From the View menu you can show the layer over the page. From the Edit menu you can clear it and run recognition again. A companion article on [editing the OCR layer](https://www.gonitro.com/user-guide/mac/article/editing-the-ocr-layer) describes correcting the hidden text a word or a line at a time, without changing what is visible.

### Web

Nitro's [user guide for Nitro Workspace](https://www.gonitro.com/user-guide/nitro-workspace) covers its cloud platform. The document tools listed there on October 8, 2026 were Smart Redact, Form Extract, optimizing PDFs and intelligent document processing. It listed no article on making a scan searchable in the browser. That is a statement about the guide, not proof about the product, so ask Nitro if browser OCR matters to you.

One web tool is relevant to firms that want data. Nitro's article on [intelligent document processing tools in Nitro Workspace](https://www.gonitro.com/user-guide/nitro-workspace/intelligent-document-processing-idp-tools) describes Table Extract, which pulls tables out of PDFs for use in programs like Excel, and Form Extract, which captures form text with its labels. The article lists six supported languages and asks for a PDF of at least 150 DPI.

### Plans

When read on October 8, 2026, [Nitro's plans and pricing page](https://www.gonitro.com/pricing) described Classic as core PDF tools for Windows desktop and Standard as a plan for Windows, Mac and iOS, and it listed batch OCR among the features of the Standard plan. The page did not say in so many words which OCR functions Classic includes. If you are on Classic, check your own copy for the OCR button before assuming either way.

## Nitro features a converter will not replace

A converter reads pages and exports their content. It does not redact, stamp, compare or edit. Nitro's user guide documents all four on Windows, and a firm that uses any of them needs an editor whatever it decides about OCR.

**Redaction.** Nitro's guide to [manual redaction in a PDF](https://www.gonitro.com/user-guide/pro/article/redaction-in-a-pdf-file) describes marking content, then applying the redaction, which is permanent. Three details in that article are worth teaching: Nitro prompts you to save the result with `_redacted` added to the file name so the original is untouched, redaction does not strip metadata, and annotations have to be deleted separately. The same article describes Nitro's separate Smart Redact product as surfacing sensitive data automatically and detecting more than 30 categories of personal information.

**Bates numbering.** The guide to [adding Bates numbers](https://www.gonitro.com/user-guide/pro/article/bates-numbers) covers a prefix, a suffix and a starting number, numbering that continues across multiple files, and removal.

**Comparison.** Nitro's [Compare tool](https://www.gonitro.com/user-guide/pro/article/how-to-compare-pdf-files) has two modes: a content comparison for text-based documents, and a visual comparison at pixel level for scanned or image-based ones. The second is useful when you hold two scans of what is supposed to be the same signed page.

**Editing the page.** Make Searchable and Editable, the [Whiteout tool](https://www.gonitro.com/user-guide/pro/article/whiteout), inserting and deleting pages, and merging files all change the PDF. A converter hands back a different file and leaves the PDF as it was.

**Batch sequences.** Nitro's batch article says you can create custom batch sequences for the tasks you perform most often. If someone built one for your productions, write down what it does before you change tools.

**Working inside other systems.** The Windows guide files its [batch process tools](https://www.gonitro.com/user-guide/pro/article/batch-processing) article in a category that also lists articles on deploying an iManage Work 10 integration and on SharePoint integrations. Schema Law has no integrations with either.

In short, Schema Law does one of the jobs on this page. It has no redaction, no Bates stamping, no comparison and no way to alter a PDF. If you drop Nitro, another editor has to pick those up. The posts on [a Foxit OCR alternative](https://www.schemalaw.com/blog/foxit-ocr-alternative) and [an Adobe Acrobat OCR alternative](https://www.schemalaw.com/blog/adobe-acrobat-ocr-alternative) describe two other desktop editors, each from its own vendor's documentation.

## Nitro PDF and a hosted converter in one comparison table

Nitro PDF is an editor that includes OCR. A hosted converter such as Schema Law takes an uploaded scan and returns its text and tables. The table lines the two up from each vendor's own pages. It lists what each one does and says nothing about how well.

| Question | Nitro PDF, per Nitro | Schema Law, per its site |
| --- | --- | --- |
| What do I start with? | A PDF open in the program, or a page on the scanner | A PDF, PNG or JPEG of up to 20 MB, uploaded in a browser |
| Can I get a searchable PDF? | Yes, Make Searchable | Yes |
| Can I change words on the scanned page? | Yes, Make Searchable and Editable | No |
| Can I get Word and Excel files? | Yes. Nitro's plan guide lists export to Word and Excel | Yes |
| Can I get CSV, JSON, Markdown or HTML? | Not among the outputs in the pages read for this post | Yes |
| Can I pull a table out as data? | Table Extract, in Nitro Workspace | Tables arrive in the Excel and CSV exports |
| What do I set before recognition? | Language, quality, skew, threshold and more | The homepage says there is nothing to prepare |
| Can I see what was read before I export? | On the Mac, by showing the OCR layer | Yes, page by page on screen |
| Can I correct the recognized text in place? | On the Mac, by editing the OCR layer | No. You correct the export |
| Can I process many files? | Batch Processing on Windows, OCR Files on the Mac | You can choose several files at once, and they are read one after another |
| Redaction, Bates, compare? | Yes, on Windows | No |
| Where does it run? | Windows, Mac and iOS apps, depending on plan | In your browser. Nothing to install |
| How do I pay? | Three-year licence or per-user subscription | Monthly plans by page volume |

The free Schema Law plan covers one document a day of up to three pages, in any of the export formats. The paid plans and their page allowances are on the [pricing page](https://www.schemalaw.com/pricing).

A point in Nitro's favour that the table makes plain: on the Mac it lets you inspect and repair the hidden text. Schema Law shows you the parsed pages, and nothing in it marks a doubtful word, so checking names, dates and amounts against the original is your job.

## Running Nitro and a second OCR tool in the same office

Two OCR tools can share an office if every scan gets its text from exactly one of them. The risk in running both is a file recognized twice, with two different text layers in circulation and nobody sure which copy was searched.

### Decide who recognizes what

Write the rule by where the document is going. A production you will redact and stamp is recognized in Nitro, so recognition, redaction and Bates numbers happen in one file. Word drafts, spreadsheets, data exports and quick lookups by people without Nitro go to the converter. The same split is worked through as a desk-side routing list in the section on [keeping Acrobat and adding a second tool](https://www.schemalaw.com/blog/adobe-acrobat-ocr-alternative#keeping-acrobat-and-adding-a-second-tool).

### Handle Nitro's prompt on purpose

Nitro's Windows guide says the program may offer to run OCR when a scanned PDF is opened. In a two-tool office that prompt is where double recognition starts. Give staff one instruction for it: if the file is an original as received, press Cancel. Run recognition only on a working copy, and only when the routing rule sends that document to Nitro.

### Keep one text layer per file

- If a PDF already carries text from the converter and someone needs to redo it in Nitro on a Mac, Nitro's guide describes Clear OCR Layer on the Edit menu. Clear first, then recognize, so the file does not hold two readings.
- Never use Make Searchable and Editable on anything but a working copy. It opens the words on the page to editing, which an original should never be.
- Name outputs by tool. A suffix such as `_nitro-ocr` or `_converted` on the file name saves an argument six months later about which text a search ran against.

### A small office, worked through

A fictional example. Reyes Calloway is a five-person firm with two Nitro licences, held by the paralegals. Its scans come from three places: the copier, clients' phones and opposing counsel.

1. Everything received is saved unopened to the matter's `Originals` folder.
2. Productions going out are copied to `Working`, recognized and redacted in Nitro, then stamped.
3. Bank statements and billing records are uploaded to the converter by whoever needs them, and the Excel export is saved to `Working` with `_converted` in the name.
4. The three lawyers without Nitro use the converter, each from their own account, when they need a passage from a scan, and paste from the plain text export.
5. Once a quarter, one paralegal checks that nothing in `Originals` has a text layer it did not arrive with.

The quarterly check catches one particular slip: someone opening an original in the editor and accepting the prompt.

### Agree on the settings too

If Nitro stays, pick one set of OCR preferences for the firm and record it: language, quality level, and whether skew correction is on. Two paralegals with different quality settings will produce different text from the same exhibit, and a search that works on one copy will fail on the other. With a converter, the equivalent record is the date and the file that was uploaded.

Whichever tools you keep, the [steps on the Schema Law homepage](https://www.schemalaw.com/#how-it-works) and Nitro's own guides agree on the last one: look at the result against the page before you rely on it.
