About this tool
BMP is an old uncompressed bitmap format that produces large files but is read by almost any program. JPEG is a lossy format designed for photographs, with small files and no transparency. Choosing between them depends on where the image will be used: BMP is common for legacy Windows software and simple pixel data, while JPEG suits photographs and web images.
JPEG is lossy, so you can set the quality: a lower value gives a smaller file with some loss of detail.
The conversion uses your browser's own image engine, so nothing is uploaded and there is no file size limit beyond your device's memory. Very large images over 100 megapixels are refused to avoid freezing the page.
Frequently Asked Questions
- Will I lose quality converting BMP to JPEG?
- Some detail is lost because JPEG uses lossy compression. At 90% quality the difference is usually invisible.
- Is transparency kept?
- JPEG does not support transparency, so transparent areas are filled with the background color you pick.
- Are my images uploaded to a server?
- No. The conversion runs entirely in your browser and the files never leave your device.
