To merge PDF files into one, add two or more documents, drag them into the order you want and download the combined PDF. Each file’s pages stay together in their original order. Anything you added by mistake comes off the list with “Remove”. Quality doesn’t change, because the pages are copied exactly as they are.

How it works
- Add at least two PDFs from your computer or phone.
- Drag them into order or use the arrows; “Remove” takes a file off the list.
- Press “Merge and prepare PDF” and download the document.
Worked example
A job application asks for a single PDF: the application form (2 pages), your CV (3 pages) and your degree certificate (1 page). Add all three, put them in that order and you get one 6-page document ready to upload.
Questions people ask
How do I merge two PDFs into one on my phone?
Tap the file picker and select both files. If they’re in different folders, add one first and then the other.
Can I add more files later?
Yes. New PDFs go to the end of the list, and you move them with the arrows.
Is there a limit on how many files I can merge?
There’s no fixed number of files. The limit is 200 MB in total, and on a phone large documents simply take longer.
Do signatures and bookmarks carry over?
Not always. A digital signature isn’t valid for the new merged document, and bookmarks may be lost. Keep the originals.
