How do I merge multiple PDF files into one?

Drop your PDFs into the upload zone, drag them into the order you want, and click Merge. You'll get a single combined PDF ready to download in seconds.

Is there a limit to how many PDFs I can merge?

You can merge as many files as you like, as long as the combined upload stays under 50 MB. There's no page limit and no daily cap.

Will merging change the quality of my PDFs?

No. Pages are copied into the new document byte-for-byte, so text, images and formatting stay exactly as they were in the originals.

Can I change the order of the files before merging?

Yes — after uploading, drag the file thumbnails into any order. The merged PDF follows the order shown on screen.

Are my files kept on your servers after merging?

No. Files are processed entirely in memory and purged the moment your merged PDF is delivered. Nothing is ever written to disk.
