How to Convert JPG to BMP in Your Browser
Converting a JPG to BMP produces an uncompressed 24-bit bitmap that older Windows software and some print or legacy pipelines expect. This guide covers the steps and what to know about file size.

Step-by-step conversion
- Open /tools/jpg-to-bmp.
- Choose a JPG, JPEG, or JFIF file — the content is validated as real JPEG-family data before conversion.
- Select Convert & download.
- Save the .bmp file from your browser downloads.
File size
JPG has no alpha channel, and neither does BMP output here, so the result is fully opaque either way. Because BMP is uncompressed, the resulting file is usually much larger than the source JPG.
Privacy
Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
Convert JPG to BMP FAQ
- Why would I need BMP instead of JPG?
- Some older Windows software, print workflows, or legacy tooling specifically expects an uncompressed BMP file rather than JPG.
- Does this accept JFIF files?
- Yes. JFIF is a JPEG-based format, so .jfif, .jfi, and .jif files are accepted alongside .jpg and .jpeg.
- Is the BMP file bigger than the JPG?
- Yes, usually significantly. BMP output here is uncompressed, while JPG uses lossy compression specifically to keep files small.
- Does this add transparency?
- No. JPG has no alpha channel, and BMP output here has none either.
- Are my files uploaded?
- No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
