How to convert JPG to BMP
- Add your .JPG file - drop it in the box above or click to browse.
- Convert it to .BMP in a few seconds.
- Download your new .BMP file.
What to expect
- BMP stores raw uncompressed pixels, so file size increases dramatically - a 2 MB JPG can easily become 20 MB or more as a BMP.
- No quality is recovered: any detail discarded by JPG compression is permanently gone; the BMP looks identical to the source JPG.
- Exif metadata such as camera model, GPS coordinates, and capture date is not supported by BMP and will be lost in the conversion.
Frequently asked questions
Does converting JPG to BMP improve image quality?
No - the conversion only unpacks the compressed data; quality is exactly what the JPG contained, no better and no worse.
Why is the BMP file so much bigger than the JPG?
JPG uses lossy compression that typically shrinks file size by 10x or more; BMP stores raw pixel values with no compression, so the file size jumps back to width × height × 3 bytes for a 24-bit image.
Can I batch-convert multiple JPG files to BMP?
Yes - IrfanView's Batch Conversion (File > Batch Conversion/Rename) is the easiest option on Windows; on the command line,
mogrify -format bmp *.jpg from ImageMagick handles it in one step.Is BMP a good format for archiving photos?
Not particularly - PNG and TIFF are better lossless options; BMP is large and adds no benefit over those formats unless a specific application requires it.
