> How to scan a signature into Word as a picture, fix the white box around it, and what OCR does with signatures, logos and seals on a converted page.

To scan a signature into Word, sign a sheet of paper, scan it, save the scan as an image file, crop it, and insert it with Insert, Pictures. The signature stays a picture. When a scanned page is converted with OCR, signatures, logos and seals are not text, so they come through as pictures, stray characters or nothing.

Those two facts cover two different jobs. In the first you want a signature image in a document on purpose. In the second you are converting a signed or sealed page and need to know what the converted file will be missing. Both come down to the same point: ink that is not lettering has no text equivalent.

## Can you scan a signature into Word as a picture?

Yes. You can scan a signature into Word as a picture, and a picture is all it can be. A signature is a drawn mark, not a row of characters, so nothing in it can be typed, searched or spell-checked. Word stores it as an image that you size and position like a photograph.

Microsoft documents the method in its article on [inserting a signature in Word](https://support.microsoft.com/en-us/office/insert-a-signature-f3b3f74c-2355-4d53-be89-ae9c50022730): write the signature on paper, scan the page, save it in a common image format, and insert the picture. The same article treats a signature line, which marks where someone should sign, as a separate feature.

### What the picture is and is not

| A scanned signature image in Word | What follows from that |
| --- | --- |
| It is pixels | Search will not find the signer's name in it |
| It can be copied | Anyone who can open the file can lift it out |
| It carries no record of who placed it or when | The file alone does not show how the signature got there |
| It sits wherever it was placed | Editing nearby text can move it or cover it |

The third row is the one to dwell on. A signature image is not the same thing as a digital signature or a signature applied through a signing service. The post on [electronically signed documents](https://www.schemalaw.com/blog/electronically-signed-documents-legal) explains what those put in a file besides the visible mark, and takes up the question of validity, which this post leaves alone.

### Text that belongs with the picture

The typed name, title and date under a signature are ordinary text and should stay that way. Type them; do not scan them in as part of the image. A signature block built as a small picture with typed lines under it can be searched for the name, restyled with the rest of the document, and corrected when a title changes.

## Scanning, cropping and placing a signature image in a Word document

Sign in dark ink on plain white paper, scan the sheet, save the scan as a PNG or JPEG, crop it to the signature, and insert it into the document with Insert, Pictures. Set the height to match a handwritten signature on a printed page, then place it on its own line over the typed name.

### The procedure

1. **Sign a clean sheet.** Use unlined white paper and a black or dark blue pen with a firm line. Sign at the size you would sign a letter. Sign three or four times down the page so you can choose the best.
2. **Scan the sheet.** Place it flat on the scanner glass. A color or grayscale scan keeps the edges of the pen strokes smoother than a pure black and white one. The guide to [digitizing a firm's paper files](https://www.schemalaw.com/blog/how-to-digitize-law-firm-paper-files) covers scanner settings in full.
3. **Save as an image.** Microsoft's instructions name .bmp, .jpg and .png as common formats for this step. If the scanner offers only PDF, check its settings for an image option.
4. **Open the image in Word and crop it.** Microsoft's steps are to select the image and, on the Picture Format tab, select Crop and use the handles. Crop close to the ink, leaving a thin margin on each side.
5. **Save the cropped version as its own file.** Right-click the image and choose Save as Picture. This is the file you keep. Delete the uncropped scan of the whole sheet.
6. **Insert it where it is needed.** In the target document, click on the signature line and select Insert, then Pictures.
7. **Set the size.** Drag a corner handle, never a side handle, so the proportions hold. A height of roughly a centimetre to a centimetre and a half sits naturally over a typed name in body-size type.
8. **Print one page.** Check on paper that the signature is sharp, the right size and not touching the text.

### A reusable signature block

Microsoft's article also describes saving the picture together with typed text as a reusable block: type the text under the inserted picture, select both, and choose Insert, Quick Parts, Save Selection to Quick Part Gallery, with the gallery set to AutoText. Think about where that block is stored before you create one, because a block saved into a template that other people use is available to all of them. Keep it in the signer's own profile.

### When the signature is on a document you are rebuilding

If you are reconstructing a lost letter or form from a paper copy and want its letterhead or signature in the new file, the image step is the same: crop the mark from a scan of the page and insert it as a picture. The text around it is the larger task, and the post on [how to scan a document and change the text](https://www.schemalaw.com/blog/how-to-scan-a-document-and-change-the-text) covers it. Whether you should carry another person's signature into a rebuilt file at all is a permission question, not a technical one.

Use the picture on a signature block you control, and type the name and title under it. On a lease you are sending out for signature, the landlord and tenant lines stay typed text. An electronic signature from a signing service is a separate file. If a notary public stamp is on the scan, type the notary name so search can find it.

## Why does a scanned signature sit in a white box over the text?

A scanned signature sits in a white box because the scan recorded the paper as well as the ink. The image is a rectangle of white pixels with a signature in the middle. Laid over text, the white covers whatever is under it. The cure is to stop the overlap or to make the white transparent.

Three things combine to produce the box.

**The background is part of the picture.** A scanner has no idea which pixels are paper. It saves all of them, and paper comes out white or off-white.

**The wrapping setting lets the picture overlap text.** Microsoft's page on [wrapping text around a picture in Word](https://support.microsoft.com/en-us/office/wrap-text-around-a-picture-in-word-bdbbe1fe-c089-4b5c-b85c-43997da64a12) describes In Line with Text as placing the picture in a paragraph "just as if it were text". A picture set that way cannot cover anything. A picture set to float in front of the text can.

**The image format may not allow transparency.** A JPEG has no transparent pixels. A PNG can have them.

### Four ways to fix it

| Fix | How | Trade-off |
| --- | --- | --- |
| Keep the picture in line | Set the layout option to In Line with Text and put the signature on its own line | It cannot overlap the typed name the way a pen signature might |
| Crop tighter | Crop to the edge of the ink | The rectangle shrinks but is still opaque |
| Send it behind the text | Choose the Behind Text layout | The typed text stays readable over the white, but the picture is harder to select |
| Make the white transparent | Use Set Transparent Color and click the background | Works on an even, pure white background; see the limits |

### Limits of the transparency tool

Microsoft's instructions for [making a picture transparent in Word](https://support.microsoft.com/en-us/office/make-a-picture-transparent-in-word-128bfdb6-9906-4f9d-b4c6-e5aa22ba082f) give the path as Picture Format, Color, Set Transparent Color, then a click on the color to remove. The same page states the limits: "You can't make more than one color in a picture transparent," and areas that look like a single color may be a range of subtle variations. Scanned paper is a case in point. What looks white is a field of slightly different near-whites, so one click can leave a speckled halo round the strokes. The page also says you cannot make a picture transparent in Word for the web and have to use a desktop version of Word.

If the halo will not go, rescan. A cleaner sheet, a darker pen and a brighter scan give a background that is closer to one flat white. Then save the result as a PNG, because saving a picture with transparent areas as a JPEG fills them in again.

### The simplest answer

For a letter, the in-line placement is enough. Put the signature picture on a line of its own between the closing and the typed name, and nothing overlaps. Transparency only matters when the signature must cross a printed line or sit over a typed name the way ink does.

## What does OCR do with a signature, a letterhead logo or a seal?

OCR looks for characters, and a signature, a logo and a seal are mostly not characters. In a converted file each one may be left out, turned into a few wrong letters, or carried across as a picture. The outcome differs by converter and by page, so check every non-text mark on the scan against the output.

### What to expect from each element

| On the scanned page | What can appear in converted text | What to do |
| --- | --- | --- |
| An ink signature | Nothing, or stray letters and punctuation where the pen crossed a line | Delete the residue; note in brackets that the original is signed |
| The printed name under it | The name, as text | Check the spelling against the page |
| A letterhead logo that is a drawing | Nothing, or a picture | Rebuild the letterhead from your own template if you need it |
| A logo that includes a company name in type | The name as text, perhaps in the wrong place | Decide whether it belongs in the body at all |
| A round seal with lettering along the rim | Fragments of the lettering, out of order | Replace with a bracketed description |
| A rubber stamp across typed lines | The stamp's words mixed into the sentence, or damaged words under it | Reread those lines on the scan |
| Initials in a page margin | Two or three odd characters at the end of a line | Delete after checking they are not part of the text |

The post on [extracting signatures and dates from scanned documents](https://www.schemalaw.com/blog/extract-signatures-and-dates-from-scanned-documents) deals with reading who signed and when from a scanned signature block. Notary seals have their own post on [scanned notarized documents](https://www.schemalaw.com/blog/scanned-notarized-document).

### Choosing an output that keeps the marks

The export format decides whether the marks stay visible. A Word file made of recognized text is a new document of words. A searchable PDF is the original page picture with text added behind it, so every signature, logo and seal remains in view exactly as scanned. Schema Law's site describes its two exports in those terms: Word as editable text with its headings, lists and tables, and searchable PDF as your original file with a hidden text layer. The [formats section of the homepage](https://www.schemalaw.com/#formats) lists both.

That leads to a simple rule. When the signature or seal is why the document matters, keep the scan or a searchable PDF as the record and use the Word file only to work with the wording. The post on [converting a signed agreement to Word](https://www.schemalaw.com/blog/convert-signed-agreement-to-word) explains how to label the Word copy so that nobody takes it for the executed document.

### Recording what the text cannot show

When a converted file drops a mark, say so in the text. A short bracketed note where the mark stood, such as `[signature]`, `[corporate seal]` or `[stamp: RECEIVED 12 MAR 2024]`, tells a reader that the page carried something the words do not. The post on [OCR and redacted documents](https://www.schemalaw.com/blog/ocr-redacted-documents) sets out a fuller convention for marking what the page shows and the text cannot.

## Whose permission does a signature image in a Word file need?

A signature image needs the permission of the person whose signature it is, for the document it is going on. Having the file is not the same as having authority to use it. What form that permission must take is a matter for your firm's policy and the rules that govern the document, not for this post.

This is a document-handling note, not legal advice. The rules on who may sign what, and how, differ between courts, agencies, jurisdictions and kinds of document. The questions to ask are the same everywhere.

### Questions to settle before placing the image

- **Whose signature is it?** Your own, a colleague's, a client's or another party's. Each raises a different level of concern.
- **Has the signer approved this document in its final form?** Approval of a draft is not approval of what goes out after later edits.
- **Is the approval recorded?** An email saying "approved, please apply my signature" with the final document attached answers the question if it is ever asked.
- **Does the recipient accept an image signature?** A court, registry, agency or counterparty may require ink, a typed signature in a set form, or a signature applied through a named system. Read the rule or the contract clause that applies.
- **Does your firm have a policy?** If it does, follow it. If it does not, ask the person responsible for risk before you start a practice of your own.
- **Would the signer be surprised to see it there?** If so, stop.

### Signatures lifted from someone else's document

A scanned agreement on your desk contains the other side's signatures, and cropping one out is easy. Do not. A signature copied from one document onto another does not show that the person signed the second one. If a converted Word file happens to carry a signature picture from the scan, delete the picture from the working copy.

### A worked example

Dana Whitcombe, a partner at the fictional firm Whitcombe Arkell, is travelling and asks her assistant to send out a routine cover letter over her signature. A careful assistant sends her the final letter as a PDF, receives a reply approving it, inserts the signature image, converts the letter to PDF, sends that PDF, and files the approval email with the letter. The same assistant, asked to put that signature on a statutory declaration, checks the rule for declarations first and may find that an image will not do.

## Keeping signature image files out of shared templates and drafts

Keep a signature image in one controlled place, insert it only into a final document, and send that document out as a PDF. Never store it in a shared template, a shared building block or a draft that circulates. Every editable file that contains the image is a copy of the signature anyone can reuse.

### Where signature images leak from

| Place | How the image gets there | What to do |
| --- | --- | --- |
| The firm letter template | Someone saved it into the template to save time | Remove it; a template should end in a blank signature line |
| A saved building block | A signature block was saved to a shared gallery | Keep such blocks in the signer's own profile only |
| Drafts sent for comment | The signature went in before the text was final | Insert it at the end, after approval |
| Precedent files | A signed letter was saved as the model for the next | Strip the image before saving anything as a precedent |
| The scanner's output folder | The sheet of practice signatures is still there | Delete it once the cropped file is saved |
| Sent email | The image was emailed from the scanner or to an assistant | Delete the message and empty the deleted items |
| The downloads folder | The image was downloaded from email on another machine | Delete it there too |

### A storage rule a small office can keep

1. **One file, one location.** Store the cropped image in a folder that only the signer and a named assistant can open.
2. **A file name that says whose it is and when it was made**, such as `Signature D Whitcombe 2026-10.png`, so an old version can be retired.
3. **Insert, finalize, convert.** The image goes into a document only after the text is approved. Save the result as a PDF and send the PDF. Keep the Word file with the image in the matter folder, not in a shared drafts area.
4. **Check before sharing any Word file.** Scroll to the signature block. If there is a picture there and the document is still a draft, remove it.
5. **Replace the image when someone leaves or a file goes astray.** Make a fresh scan under a new file name and delete the old file.

### Converted files count too

A Word file produced by converting a signed scan can contain signature pictures if the converter carries images across. Treat that file as you would any other document holding a signature image: check the signature blocks, remove what does not belong in a working copy, and leave the signed scan as the only place the signatures live.

The aim throughout is modest. A signature image is a convenience for documents the signer has approved. Controlling where the file sits, and when it enters a document, keeps it that way.
