Sign PDF
Place a signature image anywhere on a PDF.
Sign PDF lets you upload a signature image and click anywhere on a PDF's pages to place it, then download a signed copy — pairing naturally with the Signature Maker tool for creating the signature image itself.

How to use
- Upload the PDF you need to sign, then upload a signature image (a transparent PNG from the Signature Maker tool works well).
- Click "Add signature", then click anywhere on any page to place it — drag to reposition, or use the size buttons to resize.
- Click "Sign & download" once you're happy with the placement.
Common use scenarios
- Signing a contract or form without printing, signing by hand, and re-scanning it.
- Adding the same signature to multiple pages of a multi-page agreement.
- Placing a signature at a precise spot on a form that already has a signature line.
- Quickly finishing paperwork entirely from a browser, no printer needed.

How we verify Sign PDF
How to confirm the signature landed exactly where and how you wanted.
This is a visual signature, not a digital certificate
The signature is stamped as an image onto the page — it doesn't carry cryptographic identity verification the way a formal digital signature standard does.
A transparent PNG signature looks most natural
A signature image with a transparent background (like one exported from the Signature Maker tool) blends into the page without a visible white box around it.
Placement and size are adjustable before downloading
Drag a placed signature to reposition it, and use the size controls to resize it, before finalizing — check the preview carefully since this can't be undone after download.
Before you rely on the result
- You have a signature image ready — ideally a transparent-background PNG.
- You've placed the signature on every page that needs it.
- You've checked each placement's position and size before downloading.
Who this is for
- Anyone signing contracts, forms, or agreements without a printer or scanner.
- People who need to sign the same document on multiple pages.
- Anyone who already has a signature image and just needs to place it precisely.
Real-world examples
Signing a rental agreement from a laptop
A tenant receives a lease PDF, uploads a signature made with the Signature Maker tool, places it on the signature line, and emails back the signed copy — all without printing anything.
Initialing every page of a contract
A multi-page agreement requires initials on every page plus a full signature on the last — the same signature image is placed at the right spot on each page in a few clicks.
Limitations
- This stamps an image onto the page — it's a visual signature, not a cryptographic digital signature with identity verification.
Frequently asked questions
Where do I get a signature image?
Use the Signature Maker tool to draw or type one and export a transparent PNG, or upload any signature image you already have.
Is this a legally binding digital signature?
It places a visual image of your signature onto the page — it isn't a certificate-based digital signature with built-in identity verification, so check what your specific document or counterparty requires.
Can I place the signature on more than one page?
Yes — place it as many times as you need, on any pages, before downloading.
