Frequently Asked Questions
How many PDFs can I merge at once?
There is no fixed limit. You can combine as many files as your device's memory comfortably handles, since the merging happens locally rather than on a server.
Can I control the order of the files?
Yes. You choose the sequence before merging, so the pages appear in exactly the order you want in the final document.
Will merging change the quality of my PDFs?
No. Merging combines the pages as-is without re-compressing them, so text and images keep their original quality. If you also want a smaller file, run the result through the compressor afterwards.
Is merging private?
Completely. PDF62 merges your files using WebAssembly inside your browser, so nothing is uploaded, stored, or visible to anyone but you.
