Frequently asked questions
Are my PDFs uploaded anywhere?
No. The files are merged in your browser with pdf-lib and the result downloads directly — nothing is uploaded.
In what order are the PDFs combined?
In the order they appear in the list. Remove and re-add a file to change its position before merging.
Is there a limit on how many or how large?
There’s no fixed limit, but everything runs in your browser’s memory, so very large documents are bounded by your device.
My file won’t merge correctly — why?
A corrupt file can’t be loaded and the merge reports a failure. A password-protected PDF should have its password removed in its source app first — otherwise its contents may not come through correctly.
