## What this tool does
You own the file and know the password — remove it so it opens without friction.

## Typical user problems
- You know the password — but every app and colleague who opens the file needs it too. Removing it from a document you own takes one upload.
- Print shops cannot open password-protected files, and typing the password at the counter defeats the purpose. Unlock your own document before you go.
