Questions
Does merging reduce the quality?
No. Pages are copied across exactly as they are — nothing is re-compressed or re-rendered, so text stays sharp and selectable.
In what order are the files merged?
The order shown in the file list, which follows the order you added them. To move a file to the end, remove it with the cross and add it again.
How many files can I merge?
Up to 20 PDFs in one go, each up to 50 MB.
What happens to the files I upload?
Your original is deleted the moment the conversion finishes, whether it succeeded or not. The converted file stays available for 60 minutes so you can download it, then it is deleted automatically. You can also remove it instantly with the Delete file now button.
Do I need an account, and is there a watermark?
No account is needed for five conversions a day, and a free account removes that limit. Nothing is ever stamped on your document — there is no watermark on any tool, signed in or not.
Does it work on a phone?
Yes. Everything runs in the browser on a phone, tablet or computer, with no app or plugin to install.
