Why convert AVIF to BMP?

Because AVIF files use lossy/lossless compression and 12-bit HDR, they are not ideal for Uncompressed images on Windows. Converting them to BMP (uncompressed, 24-bit) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. For most practical purposes, BMP simply removes a recurring headache.
