ASF is a Microsoft streaming container that modern browsers and phones ignore completely. Re-encoding to MP4 keeps the footage but gives it a container that plays anywhere without extra codecs.
Drop your ASF file above and Morphix decodes it locally, then re-encodes it as MP4 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.
