MakeMB compresses and splits PDFs entirely on your device — fast, private, and no upload wait.
100% private
Your files are processed entirely in your browser — nothing is ever uploaded to a server.
Hit your target size
Pick 4, 5, 10, or 15MB — or set a custom limit — and MakeMB compresses images until your file fits.
Smart splitting
Still too big? MakeMB automatically splits it into balanced parts that each meet your target.
