Sign a PDF online
Add your signature to a PDF in a few steps: draw it with your finger or mouse, type your name, or use a photo of your signature on paper. Place it on the page, add the date or initials, and download the signed file. Everything happens in your browser.
Everything runs on your device. Nothing you add or type is sent to any server.
How to use it
- 01
Choose the PDF you need to sign. The first page appears with a page picker for longer files.
- 02
Create your signature: draw it in the white box, type your name and pick a style, or upload a photo of your signature on white paper.
- 03
Press Add to page. Drag the signature where it belongs and drag the round corner handle to make it bigger or smaller. You can also tap the page to move it there.
- 04
Add the date, initials or any short text if the form asks for them. Use Put on every page to initial each page at once.
- 05
Press Download signed PDF. The signature becomes part of the page itself, not a separate layer or comment.
Made for phones as well as computers
Sign with a finger on a phone, or a mouse or touchpad on a computer. The pad follows each stroke smoothly, and you can undo the last stroke or clear it and try again.
A photographed signature works too. Sign on plain white paper, take a clear photo in good light and upload it. The tool makes the light paper transparent so only the ink shows on the document. You can switch this off.
Private by design
Rent agreements, offer letters and bank forms contain personal details. This tool never uploads them. The PDF is opened, signed and saved inside your browser, and your signature is kept only until you close the page.
What kind of signature this is
The tool adds your signature as an image, the same as signing a printout and scanning it. The original text and images of the PDF are not changed or re-compressed. It is not a certificate-based digital signature (DSC) or an Aadhaar eSign, which some government and legal filings ask for. If you are not sure what the receiver accepts, ask them before you send the file.
Frequently asked questions
Is my signature saved anywhere?
No. It stays in your browser's memory while the page is open and is gone when you close it. Nothing is sent to a server.
Can I sign more than one page?
Yes. Go to any page and add the signature again, or select a placed item and press Put on every page to copy it to all pages in the same spot.
Will my PDF lose quality?
No. The signature is drawn on top of the existing pages. Their text is untouched and stays as searchable as before, and dates or initials typed in English are added as real text.
Why can't my PDF be opened?
It may be damaged or protected with a password. Remove the protection first with Unlock PDF, then try again.
