Why convert BMP to JPG?
BMP images are uncompressed and huge. JPG makes them a small fraction of the size and opens everywhere.
How it works
Drop the BMP and download a JPG. Images are decoded and re-encoded in your browser with the jsquash builds of MozJPEG, libwebp and libavif — the codecs behind Google’s Squoosh.
Quality notes
For photos the JPG looks the same at 90% quality; for pixel art or screenshots, choose PNG instead to keep sharp edges.
Common use cases
Shrinking old Windows screenshots and scanner output; sharing BMP images by email.
