BMP to JPG Converter

Convert BMP to JPG in your browser

BMP is one of the oldest image formats. It stores every pixel without compression, so a single screenshot or scan can take several megabytes. This BMP to JPG converter shrinks those files into compact JPGs that are easy to email, upload and share, while looking virtually identical.

The work is done by your browser's built-in image decoder and the HTML canvas. Your BMP is read, drawn and re-encoded locally; there is no upload, no account and no waiting on a server, so private images stay private.

Picking the JPG quality

The slider runs from 10 to 100. A value near 90 is a safe default for photos and keeps fine detail. Lower values give even smaller files with visible softening, which is fine for thumbnails. Because JPG cannot hold transparency, pick a background color for any transparent pixels in 32-bit BMP files; white is the default.

BMP vs JPG

BMP is simple and lossless but wasteful. JPG uses lossy compression tuned for photographs, which is why it is accepted by practically every website, form and app. If your image is a screenshot with sharp text or flat colors, consider PNG instead, since JPG can add small artifacts around edges. You can convert many files in one go: a single file downloads directly, while several arrive as one ZIP in which each JPG keeps the original file name.

Files that cannot be decoded, such as damaged bitmaps or rare BMP variants, are skipped and listed under the converter instead of stopping the whole batch, so the rest of your images are still converted. Old Windows bitmaps with the .dib extension are accepted too. If you need a lossless result, convert to PNG with the image converter, and if the JPG must stay under a strict size limit, resize the image or run it through the image compressor afterwards.
