How to convert JPEG to BMP
- Add your .JPEG 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
- The BMP will be several times larger than the JPEG - a 2 MB JPEG may expand to 18 MB or more as an uncompressed bitmap.
- Converting cannot restore detail JPEG compression already discarded; any existing artifacts carry over into the BMP.
- Standard BMP does not support transparency - use PNG instead if an alpha channel is needed.
Frequently asked questions
Will the image look different after converting to BMP?
No - the pixels are written as-is and the visual result is identical. Any existing JPEG artifacts carry over into the BMP.
Why is my BMP file so much larger than the JPEG?
BMP stores every pixel without compression, typically 3 bytes per pixel for 24-bit color. JPEG achieves its small size through lossy compression, which BMP does not use.
Can I batch-convert many JPEG files to BMP at once?
Yes - IrfanView's File > Batch Conversion handles this efficiently, and ImageMagick's
mogrify -format bmp *.jpg converts a whole folder from the command line.Is there any quality benefit to converting JPEG to BMP?
No - the conversion stops further quality loss if you plan to edit and re-save repeatedly, but it cannot undo the lossy compression JPEG already applied.
