Frequently asked questions

How many PDFs can I merge at once?

Free accounts can merge up to 10 files per task. Pro raises this to 30 files and unlocks unlimited downloads.

Will merging reduce the quality of my PDFs?

No. Pages are copied at their original resolution, so text stays selectable and images are untouched.

Are my files kept on your servers?

Files are deleted automatically one hour after processing on the free plan, and after 24 hours on Pro. You can also delete them manually at any time.
