BMP3 to AVIF
File Converter

BMP3 (Bitmap Image File V3) is an image file format developed by Microsoft, commonly used for storing two-dimensional digital images in a wide range of color depths. While BMP files are capable of storing detailed images without any compression—preserving the original quality—they often result in large file sizes, making them less ideal for web usage or sharing.

AVIF (AV1 Image File Format) is a cutting-edge image file format developed by the Alliance for Open Media, utilizing the AV1 video codec for highly efficient image compression. It supports a wide range of features including high dynamic range, wide color gamut, and 8-10 bit color depth, all while achieving significantly smaller file sizes compared to traditional formats like JPEG and PNG, though it may not be as widely supported across all platforms and software yet.
