BMP vs AVIF: Technical Breakdown
Why convert BMP to AVIF? While BMP excels at windows desktop backgrounds, raw pixel storage with its bmp files store color data for each pixel in the image without any compression (usually). this results in very large file sizes but ensures that the image data is exact and requires no processing to decode., it may not fit every use case. AVIF (AV1 Image File Format) offers distinct advantages in lossy & lossless environments. AVIF utilizes the advanced AV1 video codec for image compression, achieving superior efficiency. It supports 10/12-bit color depth, High Dynamic Range (HDR), and Wide Color Gamut (WCG), technically outperforming legacy JPEG encoders. Make the switch to leverage these specific benefits.
BMP (Bitmap Image File): A raster graphics image file format used to store bitmap digital images, independently of the display device. It is generally uncompressed.
AVIF (AV1 Image File Format): AVIF (AV1 Image File Format) represents a quantum leap in web image compression. Derived from the AV1 video codec, it delivers smaller, higher-quality images than any predecessor.

Expert Insights
Does converting BMP to AVIF reduce quality?
It depends on your target. AVIF utilizes lossy & lossless compression. Our engine is tuned to balance Compression Efficiency and visual fidelity, ensuring the result meets professional standards.
Is this tool truly secure?
Absolutely. We use a Browser-based / Local architecture powered by WebAssembly. Unlike server-side converters, your images never leave your device, guaranteeing 100% privacy.
Why does the file size change?
Different formats handle data differently. AVIF is engineered for next-gen web delivery, hdr photography, often providing better efficiency. For example, converting to AVIF can significantly reduce size while maintaining 10/12-bit Color Depth support.
