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.

No. PrivateRemix runs entirely on your Mac using its own processor. Your BMP files never leave the device — there is no server to upload to, and it works fully offline.
Yes. Drop in a batch of BMP files and PrivateRemix converts them all locally, saving each new JPG next to its original.
