Convert BMP to JPG
Turn BMP images into JPG files that open in practically any app or device. Everything happens in your browser, so your images never leave your device.
Why convert BMP to JPG?
BMP files are usually uncompressed, so they're far larger than they need to be and awkward to share. JPG is the format almost everything accepts, and its compression keeps photos small enough to email or upload.
File size and quality
JPG is lossy: it drops detail the eye is unlikely to notice in exchange for much smaller files. Because BMP is usually uncompressed, the JPG is often a tiny fraction of the original size. Sharp edges and text can pick up faint artefacts. You can set the JPG quality before converting; the default of 90% keeps differences hard to spot.
Where JPG files work
Every browser, operating system, photo app, office suite, print service and upload form accepts JPG. It's the safe default when you don't know what the other side can open.
Shrinking old bitmaps
Because BMP is usually uncompressed, converting a photo to JPG commonly cuts the file size by 90% or more with little visible difference. For screenshots or graphics with text, PNG keeps them sharper while still saving a lot of space.

Questions
Will converting BMP to JPG reduce quality?
Slightly. JPG is lossy, so very fine detail and sharp edges can soften a little in exchange for a much smaller file. Raise the quality setting if you see artefacts around text or edges.
Is JPG the same as JPEG?
Yes. JPG and JPEG are the same format; the shorter .jpg extension dates from older versions of Windows that only allowed three-letter extensions. Format Hero accepts both.
Are my BMP images uploaded anywhere?
No. The conversion runs in your browser, on your own device, so your images are never sent to a server. Once the page and converter have loaded, it keeps working even if your connection drops.
