JPG to AVIF Converter

1. 1Add a JPG.
2. 2Pick a quality; AVIF holds up well far lower than JPG does, so 50 to 60 is a sensible start.
3. 3Convert — encoding takes a moment longer than other formats.
4. 4Compare the saving shown, then download.

AVIF comes from the AV1 video codec, which is why it compresses so much better than formats designed decades earlier. It handles gradients and flat colour particularly well, where JPG tends to show banding and blocking.

Encoding is the catch. It is computationally heavy, and not every browser can do it: Chrome and Edge on a desktop can, while Firefox and Safari can display AVIF but not write it. This tool tests that ability before offering anything, and says so plainly rather than producing a broken file.

Because AVIF tolerates lower quality settings gracefully, the same visual result often needs a much lower number than JPG would. Start at 50, look at the picture, and raise it only if you can see the difference.

Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.

• Start at quality 50. AVIF holds up at much lower settings than JPG.
• Use Chrome or Edge on a desktop computer; other browsers can display AVIF but cannot create it.
• Compare at full size, paying attention to fine texture, which AVIF can smooth over.
• On a website, keep a JPG or WebP version as a fallback for very old software.

• JPG, PNG, WebP or AVIF: which image format should you use?
