Convert RW2 to AVIF — Best Compression
RW2 is Panasonic's RAW format and holds far more data than any web page needs. AVIF compresses the result harder than WEBP or JPG, which matters when a 20–25 MP frame has to load quickly.

Why Convert RW2 to AVIF?
AVIF is usually 20–30% smaller than WEBP again, which compounds across a gallery. The trade is encoding time and thinner support outside browsers. Note that Panasonic uses RW2 across two very different sensor sizes, so file dimensions vary far more between Lumix bodies than they do within most makers' ranges.
How to Convert RW2 to AVIF
Upload your RW2 file by dragging it in or clicking to browse.
The RAW is decoded and re-encoded with AV1. This takes longer than JPG because the encoder evaluates far more options.
Download the AVIF — typically the smallest file any of these targets will produce.
Quality Note
AVIF at quality 85 typically beats WEBP by a further 20–30%. Encoding is slower because AV1 evaluates far more options — that search is what produces the smaller file.
