Sign PDF
Draw, type, or upload a photo of your signature and place it on a PDF, privately in your browser. Paper backgrounds are removed automatically.
How to sign a PDF
- 1
Open your PDF
Drop or select the PDF you need to sign.
- 2
Create your signature
Draw it on the pad, type it, or upload a photo. A photo has its paper background removed, and you can crop and straighten it.
- 3
Place and download
Drag the signature into position, resize it, then save the signed PDF.
Why sign PDFs in your browser?
A signature is personal, and so is the document you are signing. Doing it locally means both stay on your device instead of being uploaded to a signing service.
Frequently asked questions
Is my document or signature uploaded?+
No. Everything happens in your browser, so neither your document nor your signature ever leaves your device. A live network meter on the tool shows zero bytes sent.
How do I add my signature?+
Three ways: draw it with your mouse or finger on the signature pad, type your name in a handwriting style, or upload a photo or image file of your signature.
I uploaded a photo of my signature on paper. Can I remove the white background?+
Yes. When you upload a signature photo, the paper background is removed automatically so only the ink remains, on a transparent background that sits cleanly over the document. You can adjust the ink threshold to keep fainter strokes or drop stray marks.
Can I crop or straighten an uploaded signature?+
Yes. Drag any of the four edges to crop the image down to just the signature, and use the straighten control to level a photo that was taken at an angle.
Can I sign a PDF on my phone?+
Yes. Draw your signature with your finger and drag it into place; the whole tool runs in the mobile browser with nothing uploaded.
Can I also add the date or typed text?+
Yes. Alongside the signature you can add typed text, such as your name, initials or the date, and place each item anywhere on the page.
Is this a legally binding e-signature?+
It places your signature image on the document, which is fine for most everyday agreements. For workflows that require certified signatures, identity verification or an audit trail, use a dedicated e-signature service.
Is it free?+
Yes, completely free with no sign-up and no watermark.
