Sign any PDF in your browser — draw, type or upload your signature, place it on any page, and download the signed file.
Nothing leaves your browser — your files are processed on your own device and are never uploaded to any server.
An uploaded image wins over the pad and typed name. This adds a visible signature image — it is not a certified digital signature.

How to use this tool
Drop the file in or click to pick it. It never leaves your device.
Draw on the pad, type your name, or upload a signature image — an uploaded image wins if you give more than one.
Pick the pages (last page by default) and set the position and width as percentages of the page.
Press Download signed PDF and check the signature sits where you expect before sending the file on.
Formula & worked example
Signing the last page of a contract: draw your signature, keep the default position (60% from the left, 80% from the top, 30% of page width), and the signature lands at the bottom-right of the final page.
Limitations — read this before you rely on it
This adds a visible signature image to the PDF. It is not a certified digital signature: it does not prove who signed, and it can be copied or removed by anyone with a PDF editor. For contracts where legal proof matters, use a qualified e-signature service instead. Encrypted or damaged PDFs cannot be signed here.
Frequently asked questions
It depends on your jurisdiction and the document. A visible signature image is widely accepted for everyday agreements, but it carries no cryptographic proof of identity — for high-value or regulated contracts, use a certified e-signature service.
Yes — choose 'All pages' in the page selector, or odd/even pages. The same signature, position and size are used on each selected page.
It should not: the height always follows the image's aspect ratio. If it looks wrong, the uploaded image itself may have uneven padding — trim it and upload again.
No. Signing runs entirely in your browser, and your original file is never changed.
Yes, with a full PDF editor — a visible signature image is not tamper-proof. That is exactly why it is not a certified digital signature.
