Questions about Merge PDF
Does merging reduce quality?
No. Pages are copied across as they are, so text stays selectable and images keep their original resolution. Nothing is re-encoded or flattened.
Can I choose the order?
Yes. Drag the files into the order you want before merging. The order shown is the order you get.
What if my PDFs are different page sizes?
That is fine. Each page keeps its own size and orientation in the merged file, so an A4 document and a landscape slide deck can be combined without either being stretched.
How many files can I merge at once?
Up to 20 files on the free plan, each up to 50 MB, producing up to 300 pages.
Are my files kept?
No. The files you upload and the merged result are deleted automatically within 30 minutes, or straight away if you press Delete.
