Convert PDF to Searchable PDF Mac: Preview and Live Text

To convert a PDF to a searchable PDF on a Mac, open the scan in Preview, choose File > Export, select Embed Text and save. Apple says Preview then scans for text and embeds it in the PDF so it can be selected in any PDF viewer. Live Text alone only lets you copy text from an image.

Those are two different features, and mixing them up can leave a Mac user thinking the job is done when it is not. One writes text into the file. The other reads a picture on your screen. The sections below take each in turn, using Apple's own support pages.

Can a Mac convert a PDF to a searchable PDF without extra software?

Yes, on recent versions of macOS. Preview, the PDF viewer that comes with every Mac, has an Embed Text option in its Export dialog. Apple's guide says Preview can recognize text in an image-based PDF, such as a scan or a picture of a document, and embed the text in the document.

Apple's page on how to embed text in a PDF with Preview gives the procedure in three lines:

1. Go to the Preview app on your Mac.
2. Open a PDF, then choose File > Export.
3. Select Embed Text.

Then save the export. Give it a new name so the scan you started with stays as it was.

Apple adds one note that explains a missing option: it "only appears if no text was previously recognized in the document". If the Export dialog shows no Embed Text choice, either the PDF already carries text or your version of macOS does not have the feature. The section on macOS versions below shows how to tell which.

A first run on a real file

Suppose you have a 12-page settlement agreement that opposing counsel scanned and emailed. A sensible first pass:

1. Duplicate the file in the Finder and name the copy Hale settlement SCAN.pdf. Leave it alone from here on.
2. Open the other copy in Preview and press Command-F. Search for a word you can see on page 1. No hits means the pages are pictures.
3. Choose File > Export, select Embed Text, and save as Hale settlement SEARCHABLE.pdf.
4. Open the new file. Search for a party's name, a dollar amount, and a word from the final page.
5. Drag across a sentence. If it highlights line by line, the text is there.

If you want to understand what was just added to the file, the short version is that a searchable PDF keeps each page's picture and places matching text invisibly behind it. The section on what makes a scanned PDF searchable explains the mechanism.

On the exported agreement, search for each party, the payment obligation, and any waiver printed on the first page. Then find an exhibit letter that was scanned into the same contract. If you can read a word on the page and search misses it, that line never landed in the file.

What Apple's page leaves out

The Embed Text page is brief. It does not list a language setting, a page range, a way to process many files at once, or any way to review and correct what was recognized. It does not say whether the page images are recompressed on export. For a single agreement that hardly matters. For a 2,000-page production, or a document where a wrong digit has consequences, it does.

What Live Text in Preview lets you select and copy

Live Text in Preview lets you select text that appears in a photo or image, then copy it, look it up, translate it or search the web for it. It also turns phone numbers, email addresses and web addresses in the picture into things you can click. Apple documents it for photos and images.

The actions come from Apple's page on using Live Text in Preview. You open a photo or image that shows text, hold the pointer over the text, and then:

Apple notes that if you cannot select text, you should choose Tools > Text Selection to turn on the Text Selection tool. It also says translation is not available in all languages or regions.

Where Live Text helps in legal work

Live Text is a quick way to lift a few lines out of a picture:

• A photo of a posted notice or a sign, where you need the wording in an email.
• A screenshot of a text message exchange a client sent you.
• A JPEG of a single page that someone photographed instead of scanning.
• A case number or phone number on a photographed envelope.

It is a clipboard tool. You get the words you selected, pasted wherever you put them. Nothing else about the image changes.

Scanned PDFs are a separate matter

Apple's Live Text page speaks of photos and images throughout. Its page for the case where you can't select or copy text in a PDF offers two causes only: the Text Selection tool is not selected, or the PDF needs a password. Neither page says Live Text will read the pages of a scanned PDF. The route Apple documents for a scan is the Embed Text export. If your scan arrived as a PDF, start there. For pages captured with a phone camera, the post on how to OCR a photo of a document covers getting a usable image first.

Does Preview save the recognized text into the PDF?

Only when you export with Embed Text selected. Copying text with Live Text puts words on your clipboard and leaves the file exactly as it was. The exported copy with embedded text is the one that other people, other programs and other computers can search.

The distinction decides whether your work survives the trip to someone else's machine.

Proving the text is in the file

Do not trust the Mac you made it on. Features of the operating system can make a file look more capable on your own screen than it is elsewhere. Test the exported PDF somewhere neutral:

1. Email it to yourself and open it on a Windows computer, or in a web browser's built-in PDF viewer.
2. Search for a word from the middle of the document.
3. Select a paragraph, copy it, and paste it into a plain text editor.
4. Read the pasted text against the page. Look hardest at names, dates and numbers.

Step 4 matters because a searchable file with wrong text behind the page will miss searches without any warning. A fuller routine is in the section on confirming that a PDF is really searchable.

If the copy must match the original

For a document you will file or produce, keep the untouched scan and note which file is the derivative. Apple's page does not describe what the export does to image quality, so compare the two at high zoom on a page with a signature or a seal before you send the new one anywhere. Requirements for filed PDFs differ from court to court. Check the rules of the court you are filing in.

Which macOS versions and Mac models support Live Text?

Live Text arrived with macOS Monterey in 2021, and Apple's Preview guide carries its Live Text page for macOS Monterey 12 and every later version. The guide carries the Embed Text page for macOS Ventura 13 and later, and has none for Monterey. Apple lists languages and regions for Live Text. Neither Preview guide page names specific Mac models.

Here is what each Apple source shows, as read for this post.

That last row is a gap in what this post can tell you. If you have an older Mac, the reliable test is the feature itself, not a compatibility chart.

Checking your own Mac

1. Choose Apple menu > About This Mac and read the macOS name and version number.
2. If it is Ventura 13 or later, open a scanned PDF in Preview and look for Embed Text under File > Export.
3. If it is Monterey 12, expect Live Text on images but no Embed Text.
4. If it is older than Monterey, neither feature is documented for your system. Use one of the other apps described below, or a different computer.

Language is the other requirement

A Mac set up for English may not recognize a document in a language that is missing from Apple's Live Text list. Apple's Embed Text page offers no language picker, so there is nothing to adjust if the result is poor. For a contract in a language outside that list, or one that mixes two scripts, test a page before you rely on the output. The post on OCR for foreign-language documents explains what to check.

Scanning with an iPhone into a PDF on the Mac

An iPhone can scan paper straight into a PDF on your Mac. With Continuity Camera you start from the Mac, capture the pages with the phone, and the scan appears on the Mac as a PDF. You can also scan in the Notes app on the phone itself. Neither Apple page says the resulting PDF is searchable.

From the Mac, with Continuity Camera

Apple's page on scanning documents with Continuity Camera lists the built-in Mac apps that support it, including Finder, Mail, Messages, Notes, Pages and TextEdit. The steps:

1. Open a supported app on your Mac.
2. Control-click where you want the scan to go and choose Scan Documents. You might need to select Insert from iPhone or iPad first. The same command is in the File or Insert menu.
3. The Camera app opens on the phone. Place the document in view and wait for the scan to finish. To capture manually, tap the Shutter button, drag the corners to fit the page, then tap Keep Scan.
4. Add more pages, or tap Save when you are done.

Apple says the scans then appear as a PDF in the window on your Mac. Its stated requirements are macOS Mojave 10.14 or later, iOS 12 or later, Wi-Fi and Bluetooth turned on for both devices, and both signed in to the same Apple Account with two-factor authentication.

Preview has its own entry point. Apple's page on scanning a document in Preview says to choose File > Import from iPhone or iPad, then Scan Documents. That lands the scan in the same app where Embed Text lives, which saves a step.

On the phone, with Notes

To scan a doc to PDF on an iPhone without the Mac nearby, Apple's page on how to scan documents on your iPhone describes the Notes route:

1. Open Notes and select a note or create a new one.
2. Tap the Attachment button, then tap Scan Documents.
3. Place the document in view of the camera. In Auto mode it scans by itself. Otherwise tap the Shutter button, drag the corners to fit, and tap Keep Scan.
4. Tap Done, or add more scans.

The same Apple page describes scanning from the Files app and saving to a location you choose.

Then make it searchable

Treat a phone scan like any other image-only PDF until you have proved otherwise. Open it in Preview on the Mac, press Command-F and search for a word on the page. If nothing is found, export it with Embed Text.

Phone scans vary more than flatbed scans. Before a client meeting or a records visit where you will scan with a phone, three habits help: lay each page flat on a dark surface, avoid overhead lights that throw your hand's shadow on the paper, and check each capture for cut-off edges before you move to the next page.

Mac apps that write a text layer into a scanned PDF

When Preview's export is not enough, other Mac software writes a text layer into a scanned PDF: PDF editors with a recognition command, free scanning programs, and command-line tools. Each puts the text in the file itself. They differ in controls, in batch handling and in whether your document leaves the Mac.

Reasons you might need more than Preview: an older macOS, a language setting, a stack of files, a need to correct what was recognized, or a need for an output other than PDF.

These rows describe what each maker says. They are not a ranking, and none of them is a claim about how correctly a tool reads your pages.

A note on the command-line route

OCRmyPDF is run from Terminal, and its installation instructions cover macOS through Homebrew. It runs on your own Mac, which suits documents that may not be uploaded anywhere. It also assumes someone at the firm is comfortable installing software from a command prompt. If that is nobody, pick another row. The commands themselves are set out under free and open-source routes to a searchable PDF.

How to convert a scanned PDF to Word on a Mac

A searchable PDF is still a PDF. If the goal is an editable Word document, there are two routes on a Mac.

• Copy and paste. Once the PDF has embedded text, select what you need in Preview, copy it, and paste it into Word or Pages. You get the words without the layout. Numbered clauses, tables and footnotes will need rebuilding by hand, which is tolerable for two pages and miserable for forty.
• Convert to Word directly. A converter with a Word export keeps headings, lists and tables as Word structures. The guide on how to convert a scanned PDF to Word covers the method and what to check afterwards.

Schema Law is one such converter. It runs in the browser, so there is nothing to install on the Mac. You upload a PDF, PNG or JPEG of up to 20 MB and export Word, a searchable PDF or other formats listed on the homepage. It is a website, so the document is uploaded. That makes it the wrong choice for anything that must stay on your own machine.

Choosing among them

• One short document, current macOS: Preview's Embed Text.
• Many documents, or you want to correct the recognized text: a PDF editor with those controls.
• Nothing may leave the Mac and you have technical help: a local command-line tool.
• You need Word or a spreadsheet out of it: a converter.

The options on Windows, and in software a law office may already have installed, are compared in the guide to making a PDF searchable without Acrobat.
