Frequently asked questions
Is my PDF uploaded anywhere?
No — the merge happens entirely in your browser using JavaScript. Your files never leave your device.
Can I change the order of the files before merging?
Yes — use the arrow buttons on each file to move it up, down, to the top, or to the bottom of the list. The files are merged in the order shown.
What happens if one of my files is corrupt or password-protected?
That file is flagged with an error and automatically excluded from the merge — the rest of your files will still merge normally as long as at least two are readable.
