FAQ
Will my PDF be uploaded to a server?
No. All encryption and decryption runs entirely in your browser. Neither the PDF nor the password is uploaded, and memory is cleared on download or refresh.
Which readers can open the encrypted PDF?
It uses standard PDF encryption, so major readers — Adobe Acrobat, Chrome, Edge, Safari, and mobile PDF apps — open it normally with the password.
Can I recover a forgotten password?
No. The password is used only in your browser — never uploaded or stored — so this tool cannot recover or reset it. Keep your password safe; a password manager is recommended.
What does decryption require?
You need the PDF's original open password. Switch to Decrypt, upload the file, enter the correct password, and a password-free PDF is generated once verified.
Does encryption affect the PDF content or quality?
No. Encryption only adds a password layer around the file. The text, images, and layout stay exactly the same, and clarity is unaffected.
What if it says Wrong password?
The password you entered doesn't match this PDF's open password. Check it carefully (mind case and spaces). Note that some PDFs have separate open and owner passwords — this tool uses the open password.
