Common questions

Is a signature added this way legally valid?

In the United States, the Electronic Signatures in Global and National Commerce Act says a signature or contract may not be denied legal effect solely because it is in electronic form. The same act lists exceptions, including wills, adoption, divorce and other family law, and court documents. Many other countries have similar laws. When in doubt, ask whoever sent you the document whether an electronic signature is accepted; this is general information, not legal advice.

Is this a digital signature with a certificate?

No. It places a picture of your signature, your initials and the date on the page, which is what most everyday forms, contracts and letters ask for. It does not add a certificate-based digital signature, which some government portals and banks require.

Can I sign on my phone?

Yes. Open the PDF, press Signature and draw with your finger in the box. Drag the signature into place and pull its corner to resize it. It works in Safari on iPhone and Chrome on Android.

How do I put my initials on every page?

Press Initials, create them and drag them into place on one page. With them selected, press Every page and a copy goes in the same spot on every other page.

Can I sign a PDF that has a password?

Not while it is protected. PDFs that need a password to open, or that are locked against changes, cannot be signed here. Remove the protection first, or ask the sender for an unprotected copy.

Is my signature saved anywhere?

No. Your signature exists only in this browser tab while you work, so you can sign several PDFs in a row. It is never uploaded or stored, and closing the tab removes it.

Will the PDF look different after signing?

No. The pages stay as they were, with your signature, initials, date and text added on top. Links, bookmarks and fillable fields are kept.

Is it free?

Yes, completely free, with no sign-up, no watermark and no limit on the number of documents or pages.
