Why convert ARW to AVIF?
AVIF is the most efficient mainstream image format there is. Converting ARW to AVIF runs the full RAW pipeline and encodes the result down to the smallest possible file at excellent quality — ideal when a Sony RAW photo is headed for the web. Both the RAW decode and the AVIF encode run in your browser; nothing is uploaded.
ARW vs AVIF at a glance
ARW is Sony's RAW format — every photographic detail the sensor captured, before any in-camera processing, editable but unreadable by most everyday software. AVIF is the newest mainstream image format — outstanding compression, but support outside browsers is still patchy.

ARW to AVIF — frequently asked questions
Is this ARW to AVIF converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Are my ARW files uploaded to a server?
No. The conversion happens entirely on your device using your browser's built-in image engine. Your ARW files never leave your computer or phone — which is also why the conversion is nearly instant.
Will I lose quality converting to AVIF?
AVIF uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Why convert ARW to AVIF instead of JPG?
AVIF produces dramatically smaller files than JPG at the same visual quality — the best choice when the photo is headed for a website rather than printing.
Is the conversion private?
Yes — your ARW is decoded and converted entirely inside your browser via a WebAssembly build of LibRaw; nothing is uploaded to a server.
