BMP to AVIF Conversion
BMP (Bitmap) is an uncompressed raster image format. It stores color data for every pixel without any compression, resulting in very large file sizes. While it offers high quality, its large size makes it impractical for web use.
AVIF is a modern image format derived from the AV1 video codec. It offers excellent compression efficiency and high image quality, often outperforming WebP and JPEG. It supports HDR and wide color gamut, making it a future-proof choice for web images.

BMP represents the absolute worst file size efficiency possible - zero compression, raw pixel data, enormous files. Converting to AVIF applies the absolute best compression available today - next-generation AV1 codec technology. This combination achieves the most dramatic file size reduction possible between any two image formats.
Converting BMP to AVIF reduces file sizes by 96-99% while maintaining remarkable visual quality. A 60MB BMP becomes 600KB-2MB as AVIF depending on quality settings - truly staggering compression from removing BMP's wasteful uncompressed structure and applying cutting-edge algorithms. AVIF supports transparency, HDR, wide color gamut, and all modern features BMP completely lacks. Essential for extreme file size reduction while preserving quality, modernizing legacy BMP archives, or achieving maximum web performance. Browser support growing (Chrome 85+, Firefox 93+, Safari 16+) - cutting-edge compression for modern applications.
