Frequently asked questions
How many PDFs can I merge at once?+
There's no fixed cap in the tool: pick as many as you want in one go, or drag files in over several drops to keep adding to the list. The only real limit is your browser's memory for very large batches.
Can I control the order the PDFs get combined in?+
Yes. Every file you add shows up in a list with up/down arrows, and you can reorder it however you like before merging, so the final PDF follows that exact order.
Will merging touch the quality of my original pages?+
No. Pages are copied as-is into the new file, so text, images and vectors come out identical to the source. Your original PDFs are never modified. Only a new merged file gets created, and it all happens locally in your browser.
