Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit on the free tier for reasonable personal use. If you're combining a very large batch regularly, the Pro plan removes rate limits entirely.
Will my files be stored or shared?
No. Files are processed in a temporary location and deleted immediately after your merged PDF is generated — nothing persists on our servers.
Does merging reduce PDF quality?
No. Merging combines the original pages as-is; there's no re-encoding or compression involved.
Can I reorder pages before merging?
Yes — drag the file rows into the order you want. Files are combined top to bottom in the order shown.
