Image to AVIF
Encode JPG, PNG or WebP as AVIF โ with an honest browser-support check.
About this encoder
Encodes ordinary images as AVIF using the browser's own encoder โ with a capability check that runs first and tells you plainly whether this browser can encode AVIF, instead of failing mysteriously at download time. Quality slider, batch drops, live before/after sizes.
Why the capability check exists
Every current browser can READ AVIF; writing it is another matter โ Chrome, Edge and Firefox ship encoders, Safari (at the time of writing) does not, and a tool that discovers this on your behalf beats one that lets the download fail. When the banner shows green, expect real savings: AVIF typically lands 30โ50% smaller than JPG at matching visual quality, which is why image CDNs adopted it first and why converting your site's images pays in load time. Quality 60 is the photographic sweet spot; graphics tolerate lower. Two honest caveats: receivers with older software may not open AVIF (the reverse converter exists for exactly that), and re-encoding an already-compressed JPG can't recover detail the JPG already discarded โ the savings come from AVIF's better compression, not from magic. WebP is the older, more-compatible sibling when AVIF feels too early; How to reduce image file size without wrecking it maps the whole territory.
Frequently asked questions
Why does it say my browser can't encode AVIF?
Decoding and encoding are separate: all browsers read AVIF, but only Chrome, Edge and Firefox currently write it. The check runs a real test encode rather than guessing from the browser's name.
How much smaller will my images get?
Photos typically drop 30โ50% versus JPG at the same visual quality. Already-tiny images and simple graphics save less โ the before/after sizes show the truth per file.
What quality setting should I use?
60 for photos โ visually clean with strong savings. Lower (40โ50) works for screenshots and graphics; above 80 the savings mostly evaporate.
Who can open the AVIF files I make?
Every modern browser, and increasingly the big editors. Older desktop software may refuse them โ the AVIF to JPG converter undoes the trip when someone's software objects.
