Your passwords never leave this browser tab — everything runs locally.
Private by design. Swap out a PDF’s current password for a new one in a single step. Your file is processed entirely in this browser tab using WebAssembly — it is never uploaded anywhere, so it stays yours even on a shared or offline computer.
Frequently asked questions
- Do I need the current password?
- Yes. You need the PDF’s existing password to change it — this tool cannot remove a password you don’t know.
- What is the new owner password for?
- It controls permissions like printing and editing. Leave it blank to default to the same password used to open the file.
- Are my passwords uploaded anywhere?
- No. Both the current and new passwords stay in this browser tab — everything runs locally, with nothing ever sent to a server.
