Convert BMP to JPG Online for Free

BMP is an old, largely uncompressed Windows format — still produced by some scanners, legacy line-of-business software, screenshot tools, and Microsoft Paint — and its files are often enormous compared to the same image saved as JPG, sometimes by a factor of 10x or more for a simple photo. Converting to JPG shrinks that down dramatically, making the file practical to email, upload, or store in bulk without eating through storage or bandwidth.

This tool decodes your BMP and re-encodes it as JPG entirely within your browser, so the conversion is essentially instant and nothing is sent to a server. Since BMP files rarely carry meaningful transparency data in practice, there's little to flatten — but on the rare BMP that does include an alpha channel, transparent regions are filled with a solid background color during conversion, matching how any other transparency-to-JPG conversion behaves here.

Use the quality slider to control the trade-off between sharpness and file size — for scanned documents or simple graphics, even a moderate quality setting will look identical to the source while cutting the file down to a fraction of its original size. Drop in one BMP or a whole folder of scanned files at once; each converts independently and, for multiple files, they're bundled into a single zip for one easy download.
