How to Sign a PDF for Free
To sign a PDF for free, open an online PDF signer, upload your document, create or upload your signature, drag it onto the signature line, and download the signed file. DocFills Sign PDF runs entirely in your browser — no Adobe subscription, no account, and your file never leaves your device.
When you need to sign a PDF
Contracts, offer letters, tax forms, rental agreements, and permission slips often require a signature. If you received a PDF by email, you need a way to sign digitally and send it back.
Step-by-step: sign a PDF online
1. Go to DocFills Sign PDF.
2. Upload the PDF from your computer.
3. Create your signature — draw with mouse/finger or type your name.
4. Drag the signature to the correct line or box on any page.
5. Download the signed PDF and email it back or save for your records.
Create a reusable signature
Use the DocFills E-Signature Generator to draw or type your signature once and save it as a PNG. Upload that image whenever you sign a new document — faster than redrawing each time.
DocFills vs Adobe Sign
Adobe Acrobat and Adobe Sign require paid plans for most signing workflows. DocFills is free for personal and small-business signing with no page limits or watermarks.
