Convert JPG to BMP
Free online JPG to BMP converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert JPG to BMP?
JPG has already thrown away some detail through lossy compression by the time you have the file, and converting to BMP can't bring any of it back. It only unpacks those same compressed-looking pixels into an uncompressed container that older, pre-web software can open: legacy Windows applications, embedded device firmware, or a scientific imaging tool that predates JPG support. Use this pairing only when a specific program refuses anything but .bmp.
Tips
- This won't improve quality. It removes JPG's compression, it doesn't undo any compression artifacts already in the photo.
- Only convert to BMP when the destination software specifically asks for .bmp.
A modern photo format meeting a pre-web format
BMP predates JPG by several years and was built as Windows' internal way of storing a bitmap in memory, not as a format meant for sharing photos. Converting a JPG to BMP takes an already-compressed photo and unpacks it into that older, uncompressed structure. Every pixel gets its own stored color value, with none of JPG's space-saving compression left. The visual result looks the same as the JPG (compression artifacts and all), just packaged in a format almost no photo-sharing tool, website, or messaging app expects to receive today.
Frequently asked questions
How do I convert JPG to BMP?
Drop your JPG file into the converter above, adjust the quality if needed, and click "Convert to BMP". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the JPG to BMP conversion lossless?
Yes. BMP is a lossless format. The conversion preserves all visual information from the source file.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my JPG files uploaded to your servers?
No. All JPG to BMP conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
