Convert uncompressed BMP files to optimized JPG — reduce file size by 90%+.
Open Image CompressorBMP (Bitmap) is one of the oldest image formats — it stores pixel data with zero compression, resulting in massive file sizes. A single 12-megapixel photo as BMP is over 36 MB. BMP has no place on the modern web or in email. Converting BMP to JPG reduces file size by 90–95 % while maintaining excellent visual quality, making your images practical to share, upload, and store.
BMP is uncompressed and JPG is lossy, but at quality 85–90 the visual difference is invisible for photographs. Since BMP stores raw pixel data, the conversion to JPG at high quality produces an excellent result with no visible artefacts. The file size reduction is dramatic.
| Format | File Size | Quality | Compatibility | Use Case |
|---|---|---|---|---|
| BMP | Enormous (uncompressed) | Perfect (no compression) | Universal (legacy) | Legacy Windows apps, raw pixel data |
| JPG | Small–Medium | High (lossy) | Universal | Photos, web, email, social media |
| PNG | Large | Lossless | Universal | Graphics, screenshots, editing |
| WebP | Smallest | High (lossy or lossless) | Modern browsers | Web performance |

Why are BMP files so large?
BMP stores every pixel's colour data without any compression. A 4000x3000 image at 24-bit colour requires 36 MB of raw data. Modern formats like JPG and WebP use compression algorithms that reduce this by 90 % or more with minimal visual quality loss.
Does converting BMP to JPG lose quality?
Technically yes, because JPG is lossy. However, since BMP is uncompressed, the source quality is perfect — meaning the first JPG compression at quality 85–90 produces an excellent result with no visible artefacts in photographs.
Is BMP still used anywhere?
BMP is still used in some legacy Windows applications, embedded systems, and industrial imaging equipment. For everyday use (web, email, social media), BMP has been completely replaced by JPG, PNG, and WebP.
Should I convert BMP to JPG or PNG?
For photographs, choose JPG — it produces much smaller files. For images with text, sharp edges, or transparency needs, choose PNG. For web delivery, WebP is the best option for both types.
