AVIF is a next-generation image format developed by the Alliance for Open Media that leverages AV1 intra-frame coding to achieve roughly 50% better compression than JPEG at equivalent visual quality. BMP is one of the earliest raster image formats, storing uncompressed pixel data in a straightforward header-plus-bitmap structure that every Windows application has understood since the early 1990s.
Converting AVIF to BMP decodes the AV1-compressed pixel data, applies any embedded ICC color profile transforms, and writes the result as an uncompressed 24-bit or 32-bit raster. The output preserves every decoded pixel without recompression, making this conversion useful when downstream applications or hardware require raw, uncompressed bitmap input.
Despite AVIF's impressive compression efficiency, many legacy and industrial systems cannot decode AV1-based image data. Machine vision cameras, embedded medical imaging viewers, older label printers, and scientific instruments frequently require uncompressed BMP as their input format because their firmware predates modern codec libraries.
BMP also serves as a neutral interchange format in workflows where you want to guarantee that no additional compression has been applied. If you receive AVIF images from a web pipeline and need to feed them into a quality-assurance system that expects raw pixel data, converting to BMP ensures the analysis operates on uncompressed bitmap information.
Sharp decodes the AVIF file by invoking its built-in libvips AV1 decoder, which reconstructs the full-resolution pixel grid from the compressed bitstream. Any embedded ICC profile is applied during decoding to produce sRGB output. The decoded pixel buffer is then written as a Windows BMP file at 24 bits per pixel (no alpha) or 32 bits per pixel when the source AVIF contains transparency. No dithering or color quantization is applied.
The AVIF-to-BMP conversion is lossless in the sense that no additional quality is lost during the format change. However, AVIF is a lossy format by default, so the decoded pixels already reflect the compression artifacts present in the source file. The BMP output faithfully reproduces those pixels without introducing new artifacts. If the source was encoded at high AVIF quality (e.g., quality 80+), the BMP output will appear visually identical to the original scene.

Converting AVIF to BMP is a specialized workflow for feeding modern web images into legacy or industrial systems. The output files are large but perfectly compatible with virtually any Windows-based application.
