How to sign a PDF
A signature is what turns a draft into an agreement: a contract, a consent form, a letter, an invoice that needs your name on it. Printing, signing by hand, and scanning it back is slow, and most online signing tools upload your document to a server — which is the last place a signed contract should go. This tool lets you sign a PDF yourself, entirely in your browser.
Drop a PDF and make your signature in one of three ways. Draw it with your mouse or finger on the canvas, type your name and have it rendered in a handwriting style, or upload a photo or scan of your signature on paper. Then pick the page, click the preview to place the signature where it belongs — usually above the printed name line at the bottom of the last page — drag it to adjust, and set its size. Press Sign PDF and download the finished file.
One honest limit, stated plainly: this stamps a signature image onto the page. It is not a digital certificate. It does not prove who signed, it does not prove the document was unchanged afterwards, and it does not lock the file. For most everyday signing — an agreement between people who know each other, a form for a school or a landlord, a letter that needs your name — an image signature is exactly what a scanned handwritten signature is, and that is enough. If a contract legally requires a certified digital signature, this tool is not the right one, and no free browser tool can be.
Everything runs in your browser, so the document and your signature never leave your device. There is no daily limit, and nothing you sign is stored anywhere.

Frequently asked questions
Is this a digital signature with a certificate?
No — and this matters. This tool stamps a signature image onto the page, like a scanned handwritten signature. It does not carry a digital certificate, it does not prove who signed, and it does not lock the document against later changes. For everyday signing that is enough; for contracts that legally require a certified signature, use a certified signing service.
Can I sign more than one page?
One page per run. To sign several pages, sign the first page, download the result, and run it through the tool again for the next page. Each pass adds one signature.
Is my signature stored anywhere?
No. Your signature lives only in your browser tab while you use the tool. It is never uploaded, and it is forgotten when you close the tab.
Can I sign a password-protected PDF?
No. A locked PDF has to be unlocked first — try the Unlock PDF tool with the password, then sign the unlocked file.
Are my files uploaded anywhere?
No. Signing happens entirely in your browser. Your PDF and your signature never leave your device.
