Questions people ask
Which order do the PDFs merge in?
Exactly the order your browser sends them: the list under the drop zone shows the files in merge order, first file first. If you need a different order, stage the files again in the order you want, then merge.
Is anything changed inside my documents?
No. Pages are appended as-is; text, images and layout are untouched. The merged file gets a fresh, empty document-info dictionary; we deliberately do not stamp it with our own producer name.
What happens to the documents' own titles and authors?
A merge combines pages, not document metadata, so the merged file carries none of the inputs' Info fields. If you need one input's metadata kept, set it in your PDF editor afterwards.
How big can the files be?
Two to ten PDFs, up to 15 MB each (150 MB total). The merged output is capped at 200 MB and 5,000 pages.
What happens to my files?
Inputs are removed as soon as processing finishes; your merged PDF is available for about 10 minutes, then it is automatically deleted. No accounts, no tracking.
