How to Create a Signature in Adobe Acrobat and Sign Documents

Creating a signature in Adobe Acrobat

Adobe Acrobat lets you create a digital signature in three ways: by typing your name, by drawing one with your mouse or trackpad, or by uploading an image of your handwritten signature. Once created, you can apply it to PDF documents without printing them. The signature stays linked to your Adobe account, so you can reuse it across multiple files.

To start, open Adobe Acrobat and go to Tools in the top menu, then select Protect or Fill & Sign depending on your version. Look for the option labeled Sign or Digital Signature. Adobe will prompt you to create a new signature if you do not have one saved yet.

The first time you create a signature, Adobe asks you to choose your method. You can type your name and let Adobe stylize it, draw your signature freehand using your mouse or trackpad, or click Image to upload a photo of your handwritten signature. Each method produces a different visual result — typed signatures look formal, drawn ones look more personal, and image signatures look closest to your actual handwriting.

Key Takeaways

Adobe Acrobat stores your signature in your account so you can use it on any document without recreating it each time.
You can create a signature by typing your name, drawing it with your mouse, or uploading an image of your handwritten signature.
Once you create a signature, you apply it to a PDF by opening the document, selecting the signature tool, and clicking where you want it to appear.
A digital signature in Adobe is a visual mark only — it does not create a legally binding electronic signature unless you use Adobe's certified signing service.

Drawing your signature with your mouse or trackpad

If you choose to draw your signature, Adobe opens a white box with a pen tool. Use your mouse or trackpad to write your name or initials the way you normally would. The tool captures your pen strokes and converts them into a signature image.

Drawing works best on a trackpad or with a stylus if you have a touchscreen device. If you are using a mouse, the signature may look shaky — that is normal. You can clear the box and try again as many times as you need before saving. Once you click Create Signature or Accept, Adobe saves that version and you cannot edit it without creating a new one.

Uploading an image of your handwritten signature

To use an image of your real signature, take a photo or scan of your handwritten name on paper. Save it as a JPG, PNG, or PDF file on your computer. In Adobe, select the Image option when creating your signature, then browse to find the file.

Adobe will display your image in the signature box. If the image has a white or colored background, Adobe usually removes it automatically so only your signature shows. If the background remains, you may need to crop the image in a photo editor before uploading it. Once you confirm the image, Adobe saves it as your signature.

Applying your signature to a PDF document

After you create a signature, you can add it to any PDF. Open the document in Adobe Acrobat, then go to Tools and select Fill & Sign or Protect. Click the Sign button or icon.

Adobe displays your saved signature and asks where you want to place it. Click anywhere on the document where you want the signature to appear. You can resize it by dragging the corners of the signature box, and you can move it by dragging the signature itself. Once you are satisfied with the placement and size, click outside the signature or press Done to finalize it.

If you need to sign multiple pages, repeat this process for each page. You can also add the date and time next to your signature — Adobe usually offers this option when you place the signature.

Saving and managing your signatures

Adobe stores all your signatures in your account. When you sign into Acrobat on any device, your signatures are available. If you create multiple signatures — for example, a formal one for business and a casual one for personal use — Adobe keeps them all and lets you choose which one to use each time you sign a document.

To delete a signature you no longer need, go to your Adobe account settings, find the signature management section, and remove it from your list. You cannot recover a deleted signature, so you would need to create it again if you change your mind.

The difference between Adobe signatures and legally binding electronic signatures

A signature you create in Adobe Acrobat is a visual mark on a document — it shows that you signed it, but it does not carry legal weight on its own. If you need a signature that is legally binding for contracts, financial documents, or official paperwork, you need Adobe's Sign service or another certified electronic signature platform.

Adobe Sign uses encryption and authentication to create signatures that meet legal standards in most U.S. states and many countries. It also creates an audit trail showing when the document was signed and by whom. For everyday PDFs, a basic Adobe signature is fine. For legal or financial documents, check whether your situation requires a certified electronic signature before signing.

Troubleshooting common signature problems

If your signature does not appear on the document, make sure you clicked Done or confirmed the placement. Some versions of Adobe require an extra confirmation step. If the signature appears but looks blurry or distorted, the image file may be low resolution — try uploading a clearer photo or redrawing it.

If you cannot find the signature tool, check that you are using Adobe Acrobat (the full version) rather than Adobe Reader, which has limited editing features. Adobe Reader can view and fill forms, but it cannot create or apply signatures. If you are using the web version of Acrobat, the signature tools work the same way but may be in a slightly different menu location.

Frequently Asked Questions

Can I change my signature after I create it?

You cannot edit a signature after you save it. If you want a different signature, create a new one. Adobe lets you keep multiple signatures and choose which one to use each time you sign a document. You can delete old signatures from your account settings.

Will my signature look the same on every document?

Yes. Once you create a signature, it appears exactly the same way each time you use it. You can resize it or move it around on the page, but the signature itself does not change. If you want different signatures for different purposes, create multiple versions and save them all.

What if I sign a document and then want to remove the signature?

If you have not saved the document yet, you can undo the signature by pressing Ctrl+Z (or Command+Z on Mac) or by clicking the undo button. If you have already saved the document, you need to open it again, delete the signature, and save a new version. Some PDFs may not allow signature removal if they are locked or protected.

Can someone else use my signature if they have access to my Adobe account?

Yes. Your signatures are stored in your Adobe account, so anyone who logs in with your credentials can use them. Keep your Adobe password secure and do not share your login information. If you suspect someone has accessed your account, change your password immediately and review your recent activity.

Is a signature I create in Adobe legally valid for contracts?

A basic signature created in Adobe Acrobat is not legally binding for contracts or official documents. For legally valid signatures, use Adobe Sign or another certified electronic signature service that provides encryption, authentication, and an audit trail. Check your local laws or ask a lawyer if you are unsure whether a basic signature is acceptable for your specific document.
