    Draw a signature and place it on a chosen page, with adjustable position and size. This is an image signature, not a digital one.

    All processing happens locally in your browser. Your files are never uploaded to any server.

    Open this tool

    Draw a signature with your mouse or finger on the signature pad and place it on a chosen page, with adjustable position and size. Handy for quickly signing confirmation sheets, receipts or authorisation letters without printing and scanning.

    This is an image signature (your drawing is pasted onto the page), not a digital signature, and carries no digital-signature legal weight. Only the overlay changes - the original content stays intact.

    How to use it

    1. Add a PDF.
    2. Draw your signature on the pad with mouse or finger (draw it large - it looks sharper when placed).
    3. Choose the page (blank defaults to page 1; empty signs every page), position and width.
    4. Click Start and download the signed PDF.

    Frequently asked questions

    Is this a digital signature with legal weight?
    No. The signature is drawn as an image and pasted onto the page, so it is an image signature without digital-signature legal weight - judge usage accordingly.
    Can I sign every page?
    Yes. Leave the page box empty to stamp every page, or enter one page number to sign only that page.
    Are my files uploaded to a server?
    No. Everything runs in your browser and there is no upload endpoint, so the server never sees your content.
    How large a file can I use?
    Stay under about 100 MB and a few thousand pages. Speed and memory depend on your own device.
    Is it free? Do I need an account?
    It is completely free with no usage limit, and no sign-up or login is required.
    Does it work on phones?
    Yes, the layout is responsive. Large files and complex edits are easier on a desktop.
    Which browsers are supported?
    Any modern browser: Chrome, Edge, Firefox, Safari and their mobile versions.
    Does it work with scanned PDFs?
    Yes for page-level operations, which do not need a text layer. There is no OCR, so text cannot be pulled out of a scan.
