Editing PDFs
- Covering vs redacting a PDF: what's the difference?
A black box over text in a PDF doesn't delete it: the text can still be copied. See how to check, and how to remove text, pictures and lines from a PDF for good — free, on your device.
- How to edit supported text in a PDF
Edit supported text, review unreadable source warnings and understand cover versus redaction. Work locally in your browser.
- How to sign a PDF without uploading it
Sign a PDF with a picture of your signature or by drawing it, right in the browser. Free, no sign-up, nothing uploaded — and how an image signature differs from a certificate-based digital signature.
- How to choose an online PDF editor
Before you use an online PDF editor, check four things: is your file uploaded, does it handle your supported document formats, is the result deleted or only covered, and when do you have to sign up or pay.
