Questions
Does merging change the quality of my pages?
No. Merging copies the original page objects across without re-encoding anything, so text stays selectable and images keep their original resolution.
What happens to bookmarks and links?
Bookmarks from each source file are kept and nested under an entry for that file. Internal links are remapped to their new page numbers.
Security note
Files are checked to be what they claim (by content, not extension), processed in a sandboxed worker with no network, and deleted on the schedule your plan sets. We do not run antivirus and do not claim to — please do not upload files you do not trust. Read the security page.
