PrivateRemix handles the BMP-to-JPG conversion in a couple of clicks, with the result saved right next to your original file.
Unlike free online converters, PrivateRemix has no server. Your BMP files stay on your Mac — no upload, no cloud, no account.
Drag a BMP file into PrivateRemix, or pick one from your Mac.
Select JPG from the formats PrivateRemix offers for your file.
The new JPG appears next to the original. Nothing leaves your Mac.
