Convert BMP to JPG
Drop BMP files and download them as JPG. Neither format stores transparency. Conversion runs on your device, so large batches finish in seconds and nothing is uploaded.
How to use the BMP to JPG
- Drop or paste your BMP files (up to 200).
- Set the JPG quality (90 is visually lossless).
- Click Convert to JPG.
- Download each file or all as a ZIP.
Why convert BMP to JPG?
BMP is the uncompressed Windows bitmap format. Files are very large (3 bytes per pixel) but trivially simple, which is why some legacy software, embedded systems and wallpaper settings still require it.
JPEG is the universal photo format: every camera, phone, website and printer handles it. It compresses by discarding fine detail the eye does not notice, and it cannot store transparency.
What changes in the conversion
BMP is lossless and JPG is lossy: the conversion trades a little detail for a much smaller file. At quality 90 the difference is invisible for photos; for text and line art keep quality high or prefer a lossless target. Neither format stores transparency.

How it works on your device
Your browser decodes the BMP file into raw pixels, draws them onto a canvas and asks its built-in encoder to write JPG. Nothing is sent to a server, which is why there is no file-size limit beyond your device's memory and no queue.
