PDFs can have owner-level restrictions that prevent editing, printing, or copying text — even when no password is needed to open the file. Here is how to remove them.
If the PDF opens without a password but editing/printing is disabled, it has owner-only restrictions. These are different from open-password protection and can be removed.
Upload the restricted PDF. If prompted for an owner password, enter it if you know it. For owner-only restrictions without an open password, the tool typically removes the restrictions automatically.
Tip: After unlocking, verify the restrictions are removed: try selecting and copying text, and check that printing is available.
For owner-only restrictions (no open password required), the tool can often remove them. For documents requiring the owner password specifically, it must be provided.
