Convert BMP to AVIF - Free Online Image Converter
An uncompressed BMP carries far more data than a web page needs. Converting to AVIF produces one of the smallest possible files using the AV1 codec, ideal for shrinking a heavy bitmap on performance-focused sites. Provide a JPG or WEBP fallback for the few browsers that do not read AVIF yet.
Typical result: among the smallest possible, well below the BMP size.
