How to Sign PDF

  1. Add your PDF

    Drop the PDF you want to sign, or browse for it. It opens in your browser and is never uploaded.

  2. Create your signature

    Draw it, type your name, or upload a photo of it (the paper is taken out and it is cropped to the ink, in your browser), then click "Use this signature". It appears on the page straight away.

  3. Put it in place

    Drag the signature to where it belongs and pull a corner to resize it. Add your initials or the date, and put the signature on every page or the pages you choose.

  4. Sign and download

    Click "Sign PDF", check the signed page that is shown, then click "Download signed PDF". The signature is part of the page in the new file.

Frequently Asked Questions

What signature methods are supported?
Draw with a mouse, finger or pen, type your name and pick one of four handwriting styles, or upload a photo or scan of your signature (JPEG, PNG, WebP, HEIC, GIF, BMP or AVIF). Whichever you choose is trimmed to the signature itself and keeps its proportions.
Can I use a photo of my signature on paper?
Yes. Upload the photo and the paper is taken out and the picture cropped to the ink, in your browser: only the signature is placed on the page, and the page shows through around it. The ink keeps its own colour, or tick "Make ink black". Shadows, lined paper or printed text behind the signature can leave marks; move the Sensitivity slider left to drop them, or choose Original to use the picture as it is. Sign on plain paper in good light for the cleanest result.
Is this a legally binding signature?
We cannot tell you that. Whether a signature is accepted depends on the law where you are, the kind of document and what the other party agrees to, so ask them or someone qualified to advise you. Sign PDF places an image of your signature on the page; it is not a certificate-based digital signature. Digital Signature PDF adds one of those — a cryptographic signature that shows whether the file was changed after signing — but that does not make a document legally binding on its own either.
Can I move or resize the signature after placing it?
Yes. Drag it to move it and pull a corner to resize it — it keeps its proportions. You can also use the Smaller and Larger buttons, type an exact position in millimetres, or nudge it with the arrow keys. Remove deletes a stamp, and Undo and Redo cover every change until you download.
Can I sign multiple pages?
Yes. Under "Put this signature on", choose All pages, or Choose pages and tick the pages or type them (for example 1-3, 5, odd, even or last). Each copy is the same size and the same distance from the left and bottom edges of its page, on landscape, rotated and smaller pages too. The copies are linked: move or resize the signature on any page and every copy follows, and one Undo takes the whole change back. "Unlink page" makes one copy separate, and Remove asks whether to take it off that page or every page. Initials and the date work the same way.
Is my signature saved anywhere?
Your signature is kept only in this browser tab's session storage, so you can choose "Use saved signature" for your next document while the tab is open. It is never uploaded, "Forget" deletes it at once, and it is gone when you close the tab.
