Files saved with the long .jpeg extension are ordinary photos, yet plenty of uploaders, scripts and CMS validators only whitelist the short form. AVIF is the most efficient still-image codec in wide use and routinely halves the file size of a JPEG at matching quality, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole JPEG → AVIF conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your JPEG 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.
