Convert BMP to JPG online
Convert BMP to JPG to turn an uncompressed legacy image into something you can actually send. BMP applies no compression whatsoever, so even a modest screenshot can run to several megabytes — as a JPG it will be a fraction of that.
When should you convert BMP to JPG?
- Email an image exported from old Windows software
- Upload a legacy file to a form that rejects BMP
- Cut the storage a folder of old BMP assets takes up
- Make an old image viewable on a phone
Before you convert
Lossy, but from a lossless source
Unlike most JPG conversions, this one starts from a perfect original, so the encode is as clean as JPEG gets. It is still permanent.
For screenshots, prefer PNG
If the BMP contains text, UI, or line art, PNG gives you a small file without the ringing artifacts JPEG produces around hard edges.
What happens to your file
JPG cannot store transparency, so any RGBA, LA, or palette image is composited onto a solid white background first and then saved as RGB.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Colour mode | RGB |
| Alpha channel | Flattened onto white |
What changes
- Nothing in the picture is resampled unless you ask for it — resize, crop-to-aspect, and background removal are opt-in, so a plain BMP to JPG keeps the original pixel dimensions.
