PDF tool
Simple 3-step flow
One file at a time. Set a password, confirm it, download the locked copy.
01
Drop the file from this device. If it is already locked, unlock it first — protection applies to open files.
One PDF at a time
02
At least 4 characters, typed twice so a typo doesn't lock you out. The password never leaves this tab.
Mismatch blocks the button
03
AES-256 is applied by qpdf in this tab. Open the download once to confirm the password works before you delete the original.
Keep a backup until tested
What the workspace does
These match the tool — AES-256 on every download, a confirm field, and no recovery story because there is none.
The password becomes 256-bit AES encryption via qpdf in a worker. The file on disk is untouched until you replace it yourself.
Standard readers open it
Type the password twice — a mismatch disables the button. Four characters minimum; longer passphrases resist guessing better.
No typo lockouts
Nobody keeps a copy, so nobody can reset it. Test the download once, then decide what happens to the original.
Forgotten means lost
Privacy architecture
Cloud protect tools ask you to upload the very file you want to keep private, so they can lock it. Fileraz locks it before it ever leaves the device — because it never leaves.
Legacy cloud tools
Uploads the full document to a remote queue.
Fileraz
0 bytes leave this machine. qpdf runs in this tab.
Legacy cloud tools
Sent to a server along with the file.
Fileraz
In-memory only. Cleared after a successful protect.
Legacy cloud tools
Account recovery may exist because they hold your file.
Fileraz
Forget it and the file is unreadable. Test before deleting.
Answers
Uploads, forgotten passwords, and removing the password later.
No. Encryption runs in your browser with qpdf compiled to WebAssembly. Check the Network tab while you protect a file — nothing carrying it leaves.
The file cannot be opened by anyone, including us. Keep the original until you have confirmed the protected copy opens with the password you set.
Yes — open the Unlock PDF tool, enter the password, and download the unlocked copy.
Constraints
Minimum 4 characters for the password.
No recovery — a forgotten password means a lost file.
One PDF at a time; processing uses device memory.
