What JPG to BMP conversion does

Convert a JPG, JPEG, or JFIF image to BMP directly in your browser. BMP is a widely recognized uncompressed bitmap format still expected by some older Windows software and compatibility workflows that do not read JPG.

How to convert JPG to BMP

1. Choose a JPG, JPEG, or JFIF file.
2. Select Convert & download.
3. Save the .bmp file from your browser downloads.

Why use this conversion

BMP is the format some legacy Windows applications, print pipelines, or embedded/older tooling expect by default. Converting a JPG to BMP keeps compatibility with software that does not understand JPG.

Transparency and output quality

JPG has no alpha channel to begin with, and BMP output here is 24-bit RGB with no alpha channel either, so the result is fully opaque either way. This tool writes an uncompressed 24-bit BMP, so the file will usually be noticeably larger than the source JPG.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: JPG, JPEG, or JFIF (.jfif, .jfi, .jif), up to 25.0 MB and 8,192 px per side.
• JFIF (.jfif, .jfi, .jif) is accepted alongside .jpg and .jpeg because it is a JPEG-based format.
• Metadata is not preserved in the downloaded file.

JPG to BMP FAQ

Why convert JPG to BMP?

BMP is a widely recognized uncompressed bitmap format expected by some older Windows software, print workflows, and legacy tooling that does not read 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.

Does BMP output add transparency?

No. JPG has no alpha channel to begin with, and BMP output here is 24-bit RGB with no alpha channel either — the result is fully opaque either way.

Is BMP output compressed?

No. This tool writes an uncompressed 24-bit BMP (BITMAPINFOHEADER, BI_RGB), so the file will usually be larger than the source JPG.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
