This guide covers signing on a Windows 11 or Windows 10 desktop or laptop with Quick PDF, what Microsoft Edge offers on its own, how to make a mouse signature look good, and what to know about electronic signatures.

Signing with a mouse, trackpad, pen or image
How you sign on a PC makes a big difference to how the result looks:
- Mouse: hardest to make look natural. Draw large and slow inside the pad; the signature is scaled down when placed. Or use the typed option.
- Trackpad: use one finger and draw slowly. Some trackpads track better if you hold the click with your other hand.
- Touchscreen or Surface Pen: the most natural drawn signature on Windows.
- Image upload: sign white paper with a dark pen, take a photo with your phone or scan it, save it to the PC and upload it in Sign. This gives the closest match to your real signature.
- Typed: six script fonts give a tidy, consistent look.
Tick Save for next time to keep the signature on this PC for your account.
Microsoft Edge's built-in tools vs Quick PDF
Edge opens PDFs by default on Windows and lets you draw on the page with its Draw tool, which you can use to scribble a signature. Here's how that compares:
| Edge viewer | Quick PDF | |
|---|---|---|
| Draw on the page | Yes | Yes, in a signature pad |
| Typed signature in a script font | No | Yes |
| Upload a signature image | No | Yes |
| Reuse a saved signature | No | Yes |
| Move and resize after placing | Limited | Yes |
| Fill forms, edit text, redact | Forms only | Yes |
For a one-off scribble Edge is fine. For a signature that looks right and that you'll reuse, use Quick PDF's Sign tool.
Signing PDFs from Outlook and Gmail on a PC
- In Outlook or Gmail, download the attachment (it goes to Downloads).
- Drag it into Quick PDF and sign it.
- Click Download and give the signed file a new name, like offer-letter-signed.pdf.
- Go back to the email, click Reply and attach the signed file.
Sending back the original by mistake is one of the most common slips, so a clear file name helps. If the document is sensitive, consider adding a password before you send it; see how to send a PDF securely.
Electronic signatures: what this is and isn't
This is general information, not legal advice. The signature you add in Quick PDF is an electronic signature: an image of your signature placed on the document, just like signing a printout and scanning it, minus the printer. In the US, the ESIGN Act and UETA generally treat electronic signatures as valid for most everyday agreements.
It is not a certificate-based digital signature. Quick PDF doesn't attach a signing certificate, doesn't create an audit trail, and doesn't send documents to other people to sign. Some companies, banks or government offices require a particular signing system, and some documents need a wet signature or notarization. If you're unsure, check with whoever asked you to sign.

Troubleshooting
- The signature looks shaky. Use the typed or image option, or draw on a touchscreen.
- The uploaded image has a box around it. Crop the photo tightly around the signature before uploading, and use bright, even light so the paper looks white.
- The PDF won't open. If it's password-protected and you know the password, remove it with Unlock first.
- The form has boxes too. Fill them before signing: click each box and type. See fill out a PDF form and save it.
- I can't find the signed file. Press Ctrl+J in your browser to see downloads.

Yes, though it takes a little practice. Draw large and slowly in the signature pad; it's scaled down when you place it. If it still looks rough, the typed option with a script font usually looks cleaner.
Can I add my signature to Word documents too?

No. Quick PDF opens and signs the file inside your browser on the PC. The document isn't sent to a server, and your saved signature is kept on this device for your account.
