Sign PDF

Sign a PDF without uploading it to a stranger's server

Signing a document usually means it's sensitive — an offer letter, a lease, an NDA. Most online signing tools upload your file to their servers. This one keeps everything in your browser: the PDF and your signature never leave your device, and nothing is stored.

Create a signature by drawing it, typing your name in a handwriting font, or uploading an image (a transparent PNG looks best), then drag it onto any page and resize. Add a date or printed name if the document needs it, and download the signed file.

One honest caveat: this produces a visible, drawn-on signature — not a certificate-based digital signature with a cryptographic audit trail. It's perfect for everyday agreements; for documents that legally require verified e-signatures, use a dedicated e-signature service.

How to use it

1. Upload the PDF.
2. Draw, type, or upload your signature.
3. Place, drag, and resize it on the right page.
4. Download the signed PDF.

Frequently asked questions

Are my documents uploaded to a server when I sign them?

No. Signing happens entirely in your browser — the PDF and your signature never leave your device and are never uploaded or stored. That matters a lot for signing contracts, agreements, and other sensitive documents.

Is a signature added this way legally binding?

In many jurisdictions a clear intent-to-sign plus a reproduced signature can be legally valid for ordinary agreements, but this tool does not provide a certificate-based digital signature or an audit trail. For documents that require cryptographic e-signatures or legal proof of signing, use a dedicated e-signature service.

How do I add my signature?

Three ways: draw it with a mouse, trackpad, or finger; type your name in a handwriting-style font; or upload an image of your signature (a transparent PNG works best). Then place and resize it on any page.

Can I sign on more than one page or add a date?

Yes — position a signature on any page, and repeat for multiple pages if needed. You can also add typed text (like a date or printed name) and place it alongside the signature.

What image format works best for an uploaded signature?

A PNG with a transparent background gives the cleanest result because the page shows through around the strokes. A photo of a signature on white paper also works but may carry a visible background box.
