How to Merge PDF Files for Free
Updated October 27, 2026
You need one PDF, but you have five: a CV, a cover letter and three certificates. Merging them takes a few seconds.
Merge PDFs on this page
Drop all PDFs into the tool, drag them into the right order and click convert. You get one combined PDF. FileFlip does this in your browser, so private documents never leave your device.
On Mac without extra tools
Open the first PDF in Preview, show the sidebar with thumbnails and drag the other PDFs into it. Then save.
After merging
Check the file size. If a portal limits uploads, run the merged PDF through Compress PDF.
