    Frequently asked questions

    How many PDFs can I merge at once?

    There is no fixed limit — merge 2, 10 or 50 files. Because merging happens on your device, the only constraint is your device memory.

    Will merging reduce quality?

    No — pages are copied directly into the new PDF without re-compression, so text stays sharp and searchable.

    Can I change the order of files?

    Yes — use the ↑ and ↓ arrows next to each file before merging. The output follows the list order exactly.

    Is it safe for confidential documents?

    Yes — unlike upload-based sites, your PDFs never leave your device. Merging is done locally by your browser.
