Security PDF Tools

Control who can open, read, or edit a PDF — add or remove a password, sign it, or permanently black out sensitive text.

Fill in a PDF form and sign it — type text, tick boxes, add dates, drop your signature and initials anywhere.

Draw or type a signature and place it on the page.

Black out and permanently flatten sensitive areas.

Add a password to a PDF, encrypted with AES-256.

Remove a known password from a PDF.

Create strong random passwords in your browser — control length, symbols and ambiguous characters.

Strip the hidden metadata — camera, GPS location, date — from a photo.

Strip metadata, embedded JavaScript, attachments and annotations — leaving just the pages.

Attach any file inside a PDF so it travels with the document.

Pull every attached file back out of a PDF.

Type or draw a signature and download it as a transparent PNG.

See what's hiding inside a PDF — author, hidden metadata, scripts, attachments and comments — before you share it.
