how to convert jpg to avif
Drop your JPG file
Drag your JPG file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs Canvas API on your device to decode the JPEG and encode it as AV1 Image File Format. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the AVIF file
When the conversion finishes, the AVIF file is ready to download. Save it anywhere on your device.
FAQ
common questions
How much smaller will the AVIF be?
Typically about 50% smaller than the JPG, sometimes more. AVIF is based on the AV1 video codec — modern compression that outperforms JPEG by a wide margin at equivalent visible quality. A 2 MB JPG commonly becomes a 600–900 KB AVIF with no visible difference at normal viewing sizes.
Does AVIF have universal browser support yet?
Chrome, Firefox, Safari, and Edge all decode AVIF natively now — coverage is around 94% of modern web traffic. The gap: older mobile browsers, some legacy in-app browsers (older Facebook / Instagram in-app), and many native desktop apps still can't open AVIF. For web use you typically serve AVIF with a JPG fallback via the <picture> element; for arbitrary distribution, stick with JPG.
Will my JPG quality survive the conversion to AVIF?
Mostly. Both formats are lossy, so the converter has to decode your JPG and re-encode through AVIF's compression — a second generation of artefacts gets added on top of whatever your original JPG had. The visible difference is small at normal viewing sizes, but for archival or print use you want to start from a lossless source (PNG, TIFF, or original RAW), not a JPG.
Will the AVIF look identical to my JPG?
Visibly identical at typical web display sizes. AVIF is designed so that good lossy encodes are perceptually indistinguishable from the source. You'd only spot differences if you pixel-peeped at 100% zoom and compared certain edge cases (very smooth gradients, high-contrast text), and even then the AVIF is usually closer to the original than a re-saved JPG would be.
Why is the AVIF conversion slower than other format conversions on this site?
AVIF encoding is computationally heavy — the AV1 codec was designed for the best possible compression, not the fastest. The encoder explores many possibilities per image block to find the smallest representation that still looks good, which takes time. Expect a few seconds per photo. Decoding (going AVIF→JPG) is much faster.
