Printing a document just to sign it and scan it back wastes paper and time. You can sign a PDF directly, on a computer or a phone, in about a minute.
Sign a PDF in 4 steps
- Open Sign PDF and choose your PDF.
- Create your signature: draw it with your mouse, finger or stylus, type your name, or upload a photo of your signature.
- Place it on the page and resize it to fit the signature line. Use Text to add the date or your printed name.
- Download the signed PDF and send it.
Your signature is not stored: it stays on your device and is gone when you close the page.
Tips for a clean signature
- Uploading a photo? Sign with a dark pen on white paper and photograph it in good light. A PNG with a transparent background looks best.
- On a phone, turn it sideways for more room to draw.
- Several pages to initial? Place your initials once per page.
Fill in the form first
If the document has blanks to fill in, use PDF Forms to type your details, then sign. Before sending, Flatten PDF locks the answers and signature into the page so they can't be changed or moved.
Is it legally valid?
It's a simple electronic signature, which many everyday documents accept: rental forms, school permissions, delivery notes, internal approvals. Some contracts require a certified digital signature issued by an identity provider. If you're not sure, ask whoever sent you the document.
Sign a PDF on Windows, Mac, iPhone or Android
The steps are the same everywhere because Sign PDF runs in the browser: Chrome, Edge, Safari or Firefox. On a computer, draw with the mouse or touchpad, or type your name; on a phone or tablet, draw with your finger. Nothing to install, and the document isn't uploaded.
Asking someone else to sign
Send them the PDF: they can sign it the same way on their own device, for free.
Common questions
Can I sign a PDF without Adobe?
Yes. You don't need Adobe Acrobat or any account: open Sign PDF in your browser, add your signature and download the file.
How do I add a date next to my signature?
Choose Text, click next to the signature line and type the date.
Can the signature be moved after I send the PDF?
A signature added with GrovePDF is drawn into the page. To lock form answers too, run the file through Flatten PDF before sending it.
