What is a BMP file?
BMP (Bitmap Image File) is an uncompressed raster image format originally developed by Microsoft for Windows. Introduced in the early 1990s, BMP stores pixel data with little to no compression, resulting in very large file sizes — a 1920x1080 image at 24-bit color depth produces a roughly 6MB BMP file. BMP supports various color depths (1-bit monochrome, 4-bit, 8-bit, 16-bit, 24-bit, and 32-bit with alpha). While BMP files preserve perfect image quality since there is no compression, their enormous file sizes make them impractical for web use, email, or modern workflows.
BMP vs JPG — What's the difference?
BMP stores raw, uncompressed pixel data, preserving every detail at the cost of enormous file sizes. JPG uses lossy compression to reduce file sizes by 90-95% compared to BMP, with only minor visual quality reduction. A 6MB BMP photograph typically compresses to 200-500KB as a JPG. BMP is essentially a raw pixel dump, while JPG intelligently discards imperceptible visual details. BMP has no practical advantages over JPG for photographs — it is a legacy format from an era when disk space was measured differently.
When should you convert BMP to JPG?
Convert BMP to JPG whenever you need to share, upload, or store bitmap images more efficiently. BMP files are typically 10-50x larger than equivalent JPGs, making them impractical for email attachments, web uploads, or cloud storage. If you have BMP files from older Windows applications, screenshots from legacy software, or exports from older scanners, converting to JPG will dramatically reduce file size while maintaining excellent visual quality.

Frequently Asked Questions
Is this converter really free?
Yes, completely free with no limits on file count or file size (up to 100MB per file).
Are my files safe?
Files are processed on secure servers and automatically deleted after 15 minutes.
How much smaller will the JPG be compared to BMP?
Typically 90-95% smaller. A 6MB BMP photograph usually converts to a 200-500KB JPG with no visible quality difference at our 85% quality setting.
Is there quality loss when converting BMP to JPG?
BMP is uncompressed, so converting to JPG introduces the first generation of lossy compression. At our 85% quality setting, the difference is virtually invisible to the human eye for photographic content.
Why are BMP files so large?
BMP stores every pixel's color value individually with no compression. Each pixel in a 24-bit BMP uses 3 bytes. A 1920x1080 image has over 2 million pixels, requiring roughly 6MB of raw data plus a small header.
