Frequently asked questions

Is my PDF uploaded anywhere?

No. The page is rendered and the signature is embedded entirely inside your browser with pdf.js and pdf-lib. Your document and your signature never leave your device.

Is this a legally valid signature?

This tool adds a simple electronic signature — your signature image stamped onto the page. That is enough for most freelance contracts, NDAs, rental agreements and internal approvals. It is not a certificate-based digital signature, and for high-stakes legal documents you should use a certified e-signature service.

Can I sign more than one place in the same PDF?

Yes. Click once for each spot — initials on every page, a signature on the last page, or both. Each placement can be dragged to adjust it, and the list below the preview removes any single one.

How do I get the cleanest signature?

A transparent PNG of your signature on white paper works best: sign with a dark pen, photograph or scan it, and upload the image. The draw pad works well with a mouse, trackpad or stylus.

What does the free version include?

One PDF up to 50 MB or 200 pages, with draw, type and upload signatures, click-to-place and drag-to-move, and unlimited signing — no daily cap. Sign PDF Pro ($29 one-time) removes the limits, adds a saved signature library and batch signing, and removes ads.
