When you legitimately need to remove a PDF password
The most common reason isn't anything nefarious — it's a bank statement, utility bill, or scanned form that arrived password-protected and now needs to be merged, edited, or archived without re-entering the password every time. If you already know the password, removing it is just a matter of decrypting the file and re-saving it without encryption.
PrivaPDF asks for the password once, uses it locally inside your browser to unlock the file, and then discards it — the password itself is never transmitted anywhere, only used momentarily by the WebAssembly engine running on your device.
