What a signature on a PDF means

A visible signature shows that a person has signed the document, but a drawn image alone is not a cryptographic signature. For contracts and formal submissions, the recipient may require a digital certificate or a recognised e-signature service. This tool is for the common case of adding a handwritten mark to a form or letter.

Where the signature should go

Place the signature on the intended line, at a size that matches the document rather than filling the page. On multi-page documents, sign the pages that actually require it, such as the final page and any initialled clauses. Check that the mark does not cover important text.

Flat PDFs and fillable forms

If the PDF is a flat scan, the signature is applied as an overlay. If it is a fillable form, sign after the fields are completed so the final file reflects the whole document. Once the PDF is signed, the mark becomes part of the page, so make the last corrections before signing.

Keeping the signed file safe

Download the signed copy and store it with your records. The original stays untouched, which means you can always return to an unsigned version if the signature needs to be redone. Results expire and temporary files are removed automatically.
