Frequently asked questions
Are my files uploaded to a server?
No. Merging happens entirely in your browser using JavaScript. Your PDFs are never uploaded, stored or seen by anyone.
Can I change the order of the files?
Yes. Use the up and down arrows next to each file to arrange them, then merge. The final PDF follows that order top to bottom.
Is there a limit on the number or size of files?
There's no fixed limit. Because everything runs locally, the practical ceiling is your device's available memory.
Will the quality change?
No. Pages are copied exactly as they are, so text stays sharp and selectable and images keep their original quality.
