Is there a limit on how many PDFs I can merge?

No fixed limit — it depends on your device’s memory, since every file is processed locally. Most users can merge dozens of files without issue.

Can I change the order of the files before merging?

Yes. Drag any file up or down in the list to set the order pages will appear in the final PDF.

Does merging reduce PDF quality?

No. Merging copies pages as-is — nothing is re-rendered or recompressed.
