Protect with a password
Lock a PDF so only people with the password can open it. Share the key with whoever needs it.
PDF Security
Keep your PDFs safe and under your control.
Add a password, remove one you own, redact private details for good or watermark a shared draft. Every safeguard runs in your browser, and your files are removed the moment the job is finished.
The toolkit
Protection for every situation
From locking a sensitive report to clearing a watermark, there is a tool for the job.
Unlock a PDF
Remove a password from a file you own when you no longer need the extra step to open it.
Redact details
Black out names, numbers or notes for good before you send a file outside your team.
Add a watermark
Stamp a draft or a name across each page so a shared file is clearly marked as yours.
How it works
Three steps, start to finish
Securing a document should be simple. Here is the whole flow.
- 1
Add your file
Drag a PDF in or pick one from Google Drive or Dropbox. It loads in a moment.
- 2
Pick a safeguard
Choose to protect, unlock, redact or watermark. Set the password or mark the areas you need.
- 3
Download it
Save the secured file to your device. We delete the original once the job is done.
Why it is safe
Built to keep your work private
Security tools you can trust with sensitive files — real protection and nothing left behind.
Strong encryption
Password-protected files use industry-standard encryption, so the lock holds up where it counts.
Files are never kept
Everything moves over an encrypted link and is removed after processing. We store nothing.
Redaction that sticks
Hidden text is removed, not just covered, so private details cannot be copied back out later.
Free and in-browser
There is no app to install and no account needed. Securing a PDF costs nothing at all.
