Why convert BMP to AVIF?

An uncompressed BMP can be dozens of megabytes for an image that renders identically at a fraction of the size. AVIF applies modern compression and routinely cuts the file by 80–90%, which matters if the image is going on a page you want to load quickly.

How it works

Drop your BMP file above and Morphix decodes it locally, then re-encodes it as AVIF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
