Frequently Asked Questions
- In what order are the files merged?
The order shown in the list. Drag the rows to change it before you merge.
- Are bookmarks and form fields kept?
Page content, text and images are copied exactly. Bookmarks and interactive form fields do not survive the merge.
- Can I merge a password-protected PDF?
No. Remove the password in your PDF reader first, otherwise the file cannot be read.
- Do my files get uploaded anywhere?
No. This tool runs inside your browser tab. The file is read from disk locally and the result is written back locally, so there is nothing on our side to store or delete.
- How many files can I process per day?
8 per day without an account, 20 when you are signed in. The counter resets at 00:00 UTC.
