About BMP to JPG Converter
BMP files are uncompressed and enormous, which makes them awkward to email, upload or store in bulk. JPG applies lossy compression tuned for photographic content and routinely brings the same image down to a small percentage of its original size. For scans, old digital camera output and photographs archived as bitmaps, that difference is the whole point.
Drop up to 15 BMP files (5MB each) and click Convert with JPG already set. Processing happens in your browser, so nothing is uploaded. Download the results one by one or as a single ZIP.
Match the target to the content. If the BMP is a photograph or a scan, JPG is ideal and the compression is invisible at normal viewing sizes. If it is a screenshot, a diagram, a fax, or anything containing text and hard-edged lines, JPG will add visible fringing around the edges — send those to PNG instead, which is also lossless and still shrinks a BMP dramatically. Any transparency in the source BMP is flattened onto white, as JPG has no alpha channel.

Frequently Asked Questions
Why convert BMP to JPG instead of PNG?
If you don't need lossless quality and just want the smallest possible file — for email, upload forms, or web use — JPG's lossy compression shrinks BMP's typically large, uncompressed file size much further than PNG can.
What happens to a BMP's alpha channel when converting to JPG?
It's discarded. Most BMP files don't carry transparency, but 32-bit BMPs that do will have that channel flattened away since JPG has no alpha support.
Is any quality lost converting BMP to JPG?
Yes, JPG applies lossy compression (BMP itself has none), though this tool converts at maximum JPG quality so the difference is minimal for most images.
Are my images uploaded to a server?
No. Conversion happens locally in your browser.
