Frequently Asked Questions

Is there a limit on how many files I can merge?

You can upload up to 50 files at once. The total combined file size must be under 300 MB.

Can I change the order of the files before merging?

Yes, after uploading you can drag and drop the files to reorder them freely. Just arrange them the way you want and then click Merge.

Do I need to install anything?

No installation or sign-up required. It works right in your browser on Windows, Mac, smartphones, and any other device.

Will merging reduce the PDF quality?

No. The tool only combines the files — it does not recompress images or text, so the original quality is fully preserved.

Are my uploaded files stored on a server?

No. Everything is processed entirely in your browser, so your files are never sent to any server. Your privacy is completely protected.
