Restricted versus encrypted

A restricted PDF opens fine but refuses to print, copy or edit. Those limits are set by an owner password, and they are honoured by the reader as a matter of convention — the document itself is perfectly readable. Re-saving the file drops the restrictions without touching a single page.

An encrypted PDF will not open at all without its user password. Here the content is genuinely scrambled, and no tool can read the pages until the correct password is supplied. There is nothing to be clever about: the password is the key.

Statements that arrive locked

Banks, insurers and utilities routinely send statements encrypted with something derived from data they already hold about you — a customer number, a date of birth, the first letters of a name, sometimes a combination in a documented format.

The covering email almost always states the format. Once you have opened the document once, removing the password gives you a copy you can search, print and file without typing it every time.

What to expect from the result

A restricted file is re-saved as it is: the pages, the text layer and the size all come back essentially unchanged.

A file that needed its open password has to be rebuilt from what was decrypted, so the copy may lose its text layer and change size. That is a real trade — keep the original alongside it.

The line worth not crossing

Unlocking a document you are entitled to open is ordinary housekeeping. Trying to get into someone else's document is not, and no tool that works by brute force belongs in a browser tab anyway. If you do not have the password, the answer is to ask whoever sent it.
