FAQ

Can I change the order before merging?

Yes. The queue shows file names and supports moving files up or down before upload.

How many PDFs can I merge?

Use small batches within the 25 MB per-file upload limit for the most reliable result.

Will bookmarks be preserved?

Page content is the priority. Complex bookmarks or outlines may need to be checked after merging.
