Why convert MKV to AVI?

Set-top boxes, car screens and legacy editing suites often list AVI as the only supported container. This tool re-encodes MKV to MPEG-4 video in AVI so those devices finally play the file.

How it works

Drop your MKV file above and Morphix decodes it locally, then re-encodes it as AVI 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.
