A real use case

A landlord emails a month-to-month lease renewal as a PDF and needs a signature back the same day, with no printer or scanner at home. Open Sign PDF, draw a signature with a trackpad or finger, drag it onto the signature line, and download the signed copy to email straight back — no printing, signing on paper, or re-scanning involved.

Why sign with Sign instead of printing and scanning?

✍️ Sign a PDF online free without creating an account or emailing your signature to anyone.
🖊️ Draw your signature with a mouse, trackpad, or finger, or type it in a handwriting-style font — whichever feels more like your real signature.
🔒 The signature is placed on the page entirely in your browser, so the document you're signing is never uploaded.
💸 Free, with no watermark added and no limit on how many PDFs you sign.

What actually happens to your file

Whatever you draw or type into the signature pad is captured as a transparent image directly in your browser's canvas — no photo, scan, or third-party signature service involved. When you click Sign PDF, that image is embedded onto the page you chose using pdf-lib, positioned and sized exactly where you dragged and scaled it, and the result is written to a new PDF in memory and handed to your browser to download. Your signature and the document you're signing both stay inside this tab from start to finish — there's no visible upload request in DevTools while you sign.

Limits and edge cases

This adds a visual signature image to the page — it is not a cryptographically certified digital signature (like Adobe's certificate-based signing), so it won't satisfy workflows that specifically require certified e-signatures.
The source PDF must be unencrypted; a password-protected file needs to be unlocked first, since signing reads and writes pages directly.
Signing applies to one page per pass. To sign multiple pages, download the signed file, then re-upload it to add another signature to a different page.
A PDF that carries restriction flags (even without a password) can occasionally fail to load here — if that happens, try Unlock PDF first, since some "protected but no password" files still block editing.

Is a visual signature actually enough for this document?

This tool places a signature image on the page — the digital equivalent of printing, signing by hand, and scanning a document back in. That's genuinely enough for most everyday paperwork, but not for everything. This isn't legal advice; when in doubt, ask the other party what they require before you sign and send.

Document type	A visual signature like this one
Lease renewals, informal agreements, internal approvals, acknowledgment forms	Usually accepted — matches the print-sign-scan convention most recipients already expect.
Standard business contracts and NDAs between consenting parties	Often fine — most jurisdictions recognize an intentional signature like this as valid consent — but confirm if the other party has a specific e-signature policy.
IRS and other government forms, real-estate closing documents, notarized filings	Not sufficient — these typically require a certified e-signature service or an in-person/notarized signature, not an image placed on the page.

Frequently asked questions

Is this a legally binding electronic signature?+

This tool adds a visual signature image to your PDF, similar to signing a printed page and scanning it back in. It does not provide cryptographic digital-signature certification (like Adobe's certified signatures). For contracts that require legally certified e-signatures, check the specific requirements of the other party first.

Does this work the same as printing, signing, and scanning a document?+

Visually, yes — the output looks like you signed the printed page and scanned it back in, and most recipients accept that for everyday paperwork like lease renewals or acknowledgment forms. The difference is convenience: nothing is printed, physically signed, or scanned, since the signature is placed digitally in this tab.

Can I sign more than one page?+

Yes. Add your signature to a page, apply it, then re-upload the signed file to add another signature to a different page if needed.

Is my signature uploaded anywhere?+

No. Your drawn or typed signature is rendered as an image directly in your browser and placed onto the PDF locally — nothing is sent to a server.

Can I resize or reposition the signature before signing?+

Yes, drag the signature to reposition it and use the size slider to scale it before you finalize the document.

Can I sign a PDF on a school or work Chromebook?+

Yes. This tool is a regular web page, not an app, so it works in Chrome even on managed Chromebooks where installing apps from the Play Store is blocked.
