What BMP to JPG conversion does

Convert BMP (bitmap) images into widely compatible JPG files without installing desktop software. BMP files are often much larger than JPG for the same picture, so converting can save significant space.

How to convert BMP to JPG

1. Choose a .bmp file.
2. Optionally adjust JPEG quality.
3. Select Convert & download.
4. Save the .jpg file from your browser downloads.

Dimensions and compatibility

The output JPG keeps the same pixel dimensions as the source BMP. Decoding uses your browser's native image support, so no BMP-specific library is downloaded.

Compatibility and quality

JPG is lossy. Raising quality keeps more detail and usually increases file size. Transparent or partially transparent pixels are flattened onto white because JPEG has no alpha channel — the same convention used by every other JPEG output tool on Looty Tools.

Privacy and local processing

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

Limits and known issues

• Inputs: BMP (.bmp) only, up to 25.0 MB and 8,192 px per side.
• Decoding uses your browser's built-in image support. Unusual or corrupted BMP variants may fail to decode.
• Metadata is not preserved in the downloaded JPG.

BMP to JPG FAQ

Are my files uploaded?

No. Conversion runs locally in your browser using native browser image decoding. Your file is not uploaded to Looty Tools servers for this workflow.

What happens to transparency?

Transparent or partially transparent pixels are flattened onto a white background, because JPEG has no alpha channel. This matches the white-background convention used by every other JPEG output tool on Looty Tools.

Will image quality change?

JPEG uses lossy compression. The default quality is high (90%), and you can adjust the JPEG quality slider before converting.

What BMP files are accepted?

Files with a .bmp extension and a valid BMP header ("BM" signature) are accepted. Renamed or corrupted files are rejected before decoding.

Are image dimensions preserved?

Yes. The output JPG keeps the same pixel dimensions as the source BMP.

Why did conversion fail?

Unusual or corrupted BMP variants may not decode in every browser. Try re-exporting the file, or use a current version of Chrome, Edge, Firefox, or Safari.
