How to convert BMP to JPG
Three steps.
Drop your BMPs in
Old screenshots, software exports, whatever produced them.
JPG is already the default
Still images come out as JPG on the standard setting with nothing to configure.
Hit Squish
JPGs come out under new names at sane sizes.
BMP: 1995 called
BMP is the classic Windows picture format: every pixel stored raw, no compression whatsoever. Some old software, scanners and special tools still produce it, and every BMP is roughly as big as a modern photo format’s worst-case scenario.
There is almost never a reason to keep a photo as BMP. Converting to JPG shrinks it by about 90% at a quality level you choose, and nothing about the picture changes on screen.
Good to know
- No size limits, no watermarks, no uploads.
- Whole batches convert in one go.
- The result is checked against the original before saving.

Questions, answered
Why are BMP files so huge?
Because BMP stores raw pixels with no compression at all. It was designed when pictures were small and disk space was somebody else’s problem.
Is it really free?
Yes. It costs nothing, needs no account, and whole batches run one after another. Every input format and the full quality engine are included. If you point it at a really big collection you’ll eventually meet the free limit; Pro ($9 once) removes it and adds a watch folder, or you can simply come back tomorrow.
Does it overwrite my originals?
Never. Finished files are written under new names, so the originals and the results live side by side.
Out of 1995, into a file you can email.
