Frequently asked questions
How many PDFs can I merge at once?
There is no fixed limit on the number of files. Each file can be up to 100 MB, and merging runs in your browser, so the practical limit is your device's memory.
Will merging reduce the quality of my PDFs?
No. Merging copies the original pages exactly as they are, so text stays selectable and images keep their original resolution.
Can I change the order of the files?
Yes. After adding files, use the arrows to move any file up or down. They are merged top to bottom in the order shown.
