Why convert BMP to AVIF?
BMP is an uncompressed raster format that stores raw pixel data, yielding large but universally readable files. AVIF is a next-generation format built on the AV1 codec, producing the smallest files of any mainstream format at a given quality.
AVIF supports an alpha channel, so you get a transparency-capable file to layer or edit — though the conversion cannot invent transparency the BMP never had. Moving from BMP to AVIF usually shrinks the file significantly, often by half or more, thanks to AVIF's efficient compression — great for websites, email, and saving storage. AVIF is supported across all modern browsers and is one of the best choices for website performance and Core Web Vitals.
Pixohub converts BMP to AVIF entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many BMP files into AVIF as you like. Reach for AVIF whenever you need cutting-edge web delivery where the very smallest file size wins.
BMP vs AVIF: what to expect
BMP is best for maximum compatibility with legacy Windows software and raw, lossless pixels, while AVIF shines for cutting-edge web delivery where the very smallest file size wins. Keep your original BMP if you may later need the source file, and export a AVIF copy for sharing and the web.
