How to use it
- 1Drop a BMP bitmap into the upload area.
- 2Note the original size — BMP stores pixels uncompressed, so even a modest photo can run to tens of megabytes.
- 3Set the quality slider (85 is a sensible default) and press Convert to re-encode the bitmap as JPG.
- 4Download the JPG and check the measured saving, which is typically 90% or more.
Frequently asked questions
Why are BMP files so large?
BMP writes every pixel as raw bytes with no compression at all — width × height × 3 or 4 bytes. JPG applies lossy compression tuned for photos, which is where the enormous saving comes from.
Will I see any quality loss?
At quality 85 and above the difference is hard to spot on photographic content. Screenshots and flat-colour bitmaps fare worse in JPG — convert those to PNG instead.
What about BMP files with transparency?
32-bit BMPs can carry an alpha channel, but JPG cannot. Transparent areas are composited onto the background colour you pick before encoding.
Which BMP variants are supported?
Whatever your browser can decode natively, which covers standard 24-bit and 32-bit Windows bitmaps. Very old RLE-compressed or OS/2 variants may fail to load, and the tool tells you rather than producing a broken file.
