Frequently asked questions
How do I control the order of the merged files?
The list order is the page order. Move a file up or down in the queue and the combined document follows instantly, so you can put a cover page first without renaming anything.
Is there a limit on how many PDFs I can combine?
No hard limit: the merge is bound only by your device memory, so a few dozen files or several hundred pages are handled comfortably. The whole operation runs inside your browser tab; the file is never uploaded, so nothing is stored or logged.
Are bookmarks, links and form fields kept?
Page content, layout and embedded fonts are preserved. Interactive form fields and PDF bookmarks belong to the original files and are not carried into the combined document, so flatten any forms before merging.
