PDF Encrypt / Decrypt Tool
Password-protect a PDF or remove the password — one combined client-side tool.
Password-protect a PDF or remove the password — one combined client-side tool.
PDF Encrypt / Decrypt combines protection and unprotection into a single workflow. Upload a PDF, pick Encrypt to add a user password, or Decrypt to remove a password you already know. Everything happens in your browser — the file and the password never travel over the network.
Encrypt mode rasterises the PDF (text becomes non-selectable image) — that's the trade-off of pure client-side encryption. Use a password manager to store the resulting password.
