BMP to JPG Converter
Convert BMP images to JPG in your browser — multiple files at once, adjustable quality, per-file savings shown, and a one-click ZIP download. Free.
About the BMP to JPG Converter
BMP is an old uncompressed Windows format — files are enormous (a 12-megapixel photo is ~36 MB as BMP) and many websites, forms and apps refuse to accept them. This converter turns BMP files into universally-supported JPG, typically 90–98% smaller, right in your browser.
Select multiple BMP files at once, set the JPG quality (85–95% is visually lossless for most images), and convert the whole batch in one click. A results table shows each file's dimensions, before/after sizes and the percentage saved, with individual downloads or a single ZIP for everything.
Nothing is uploaded — conversion runs locally with the canvas API, so old scans, screenshots and exported documents stay private, and even huge BMP files convert quickly because there's no upload wait.

Frequently Asked Questions
Why are BMP files so large?
BMP stores every pixel uncompressed — three or four bytes each, no exceptions. JPG compresses photographic content perceptually, which is why the same image typically shrinks by 90% or more with no visible difference at high quality.
Will converting BMP to JPG lose quality?
JPG is lossy, but at 85–95% quality the difference is invisible for photos and scans. For images with sharp text or flat graphics where you need pixel-perfect edges, consider PNG instead — our PNG to JPG tool works in reverse too.
Can I convert multiple BMP files at once?
Yes — select as many as you like. They're processed one by one in your browser and you can grab the whole batch as a single ZIP file.
Are my files uploaded to a server?
No. Decoding and re-encoding happen entirely in your browser, so the files never leave your device — no upload time, no privacy risk.
What happens to transparency in BMP files?
JPG doesn't support transparency, so any transparent areas are filled with white during conversion — the standard behavior for JPG output.
