Answers to the questions people ask most about using Sign PDF.

Is an electronic signature legally binding?

In the US (ESIGN Act and UETA), the EU (eIDAS) and many other countries, electronic signatures are legally valid for most agreements. Some documents, such as wills or notarized papers, have exceptions. This isn't legal advice.

Is this a certificate-based digital signature?

No. Sign PDF places your drawn signature on the page, which is an electronic signature, with no digital ID required. For certificate-based digital signatures, use a dedicated signing service.

Can I type or upload my signature instead of drawing it?

Sign PDF currently lets you draw your signature. Typed and uploaded signatures aren't available yet.

Can I sign more than one page?

Each run places one signature. To sign another page, upload the signed file and sign again.

Can I sign a PDF without printing it?

Yes. Sign it in your browser and send the file. There's no need to print, sign and scan.

Why can't I sign my PDF?

The file may be password-protected or have security settings that block changes. Unlock it with Unlock PDF (you'll need the password), then sign.

Is it safe to sign a PDF online?

With MyPDFMate, yes. Your document and signature stay in your browser and are never uploaded.
