BMP to JPG Converter
Convert BMP images to JPG locally — 90-99% size reduction. No upload, no watermark, free. Modernize legacy BMP files instantly.
Recommended export settings
Need to convert BMP to JPG? BMP (Bitmap) is Microsoft's legacy uncompressed image format from Windows 1.0 (1985). BMP files store every pixel exactly without compression — a single 1920×1080 BMP can be 6 MB (vs 200 KB JPEG at quality 85). Despite being obsolete for web use, many legacy systems (old scanners, industrial equipment, scientific instruments, Windows screenshots) still output BMP. This BMP to JPG converter modernizes these files with quality-aware JPEG re-encoding, typically reducing size 90-99%.
- 1BMP files are uncompressed — 10-50× larger than equivalent JPEGs. Modernizing to JPEG saves 90-99% file size.
- 2Many legacy systems still output BMP (old scanners, scientific instruments, industrial equipment).
- 3JPEG is universally supported by every modern software, browser, and device.
- 4Local processing avoids uploading legacy assets to third-party servers.
- 5Free, no account, no watermark — convert as many BMPs as you need.
- 6Quality 85 output is visually identical to source BMP for photos and complex graphics.

Frequently asked questions
Typically 90-99% reduction. BMP is uncompressed — every pixel takes 3 bytes (24-bit color) regardless of content. JPEG uses efficient lossy compression that achieves similar perceived quality at 1-10% of BMP size. A 6 MB 1920×1080 BMP becomes a 100-200 KB JPEG at quality 85.
