What is BMP?
BMP is a bitmap image format associated with Windows. It stores raster pixels and is often used without compression, so BMP files can be large compared with compressed image formats.
Converting a supported BMP to JXL lets you choose lossy or lossless compression. Results depend on the image, and your browser must be able to decode the BMP variant.
What is JXL?
JXL is the file extension for JPEG XL, an image format designed for efficient image compression. JPEG XL supports lossy and lossless compression as well as transparency, making it suitable for both photographs and graphics.
This BMP to JXL converter creates still, 8-bit sRGB images. Choose high quality to balance detail and file size, or lossless to preserve the decoded pixels. File-size savings are not guaranteed, and JPEG XL support varies between browsers and image applications. Keep your original BMP files for compatibility.
