FAQ

How many files can I merge?

There is no fixed limit; it depends on your device memory. Dozens of files of a few megabytes each merge without trouble.

Will quality drop?

No. Pages are carried over without re-encoding, so the document looks exactly like the originals.

Can I change the order?

Yes. Drag a row to a new position or use the up and down arrows.

Can I merge a PDF with JPG images?

Turn the images into a PDF with the JPG to PDF tool first, then merge that file with the others.

Are my files uploaded?

No. Merging runs in your browser, so contracts and scanned documents stay with you.

Does it work on a phone?

Yes. Pick several PDFs from your phone files, set the order and download the result.
