Add the PDF you want to protect

The original is never changed. A separate protected copy is created for download.

Files stay on this device and are removed when you close the page.

{{ progressLabel }}

The PDF could not be processed{{ errorMessage }}

How should the PDF be split? One file per pageCreates a separate PDF for every page. Custom page groupsEach comma-separated group becomes one PDF. Page groups Use page numbers and ranges separated by commas. Example: 1-3, 4, 5-8.

For consecutive groups, use the scissors on a page to add or remove a split after it.

{{ t('split.groupLabel', { number: group.number }) }}{{ t('split.groupPages', { range: group.range }) }}

Opening password Confirm password {{ t(showPasswords ? 'protect.hide' : 'protect.show') }} Choose a password and save it somewhere safe.

How protection works

A password is required to open the new copy

Your PDF is encrypted on this device and saved as a separate file protected by the password you choose.

{{ item[0] }}

{{ item[1] }}

This protects the PDF against opening without the password. It cannot prevent screenshots or copying after someone opens the file, and it does not add a digital signature.
