What you need
- A PDF under 5 MiB (25 MiB on Pro), up to 100 pages
- A desktop browser (upload and download only on a phone)
- Text you can select — not a scan
- A free account, with a confirmed email, to download
The usual corrections
- A name or address — see fix a typo. Check the signature block too.
- A date or a term — see change a date or number.
- An amount in words and in figures: change both; nothing links them.
- A word in a clause, such as shall for may.
Before or after it is signed
- Before anyone signs: correct the draft and send it as the version to sign.
- After a signature: an edited copy is a new document. A digital signature is invalidated, and a drawn one stays on words that changed, so have it signed again.
Send it back and sign
- Tell the other side what changed, or mark it with highlight and comment; remove the marks in a clean copy.
- Sign the PDF in the same editor. It is a drawn signature, not a certificate-based one.
