JPG to AVIF Features
• Modern compression algorithm for better efficiency
• Small file size saves storage space
• Quality control for optimized file size
• Perfect for website optimization
A single JPG photo can shrink by 50% or more when re-encoded as AVIF — often without any visible quality difference. Image Machine runs the entire AV1 encoding process locally in your browser, so you get web-ready AVIF files instantly without sending photos to a cloud server. Faster page loads start here.

Frequently Asked Questions
Is AVIF significantly smaller than JPG at the same visual quality?
Yes — independent benchmarks consistently show AVIF files are 40–55% smaller than JPEG at equivalent perceptual quality. A 200 KB product photo can often drop below 100 KB as AVIF, directly cutting page load times and reducing bandwidth costs for image-heavy websites.
Do all browsers support AVIF images?
AVIF is supported in Chrome, Firefox, Edge, Opera, and Safari 16.4+. It is not supported in Internet Explorer or very old browser versions. If you serve images to a broad audience, the HTML picture element lets you offer AVIF to capable browsers with a JPG fallback for others.
Does AVIF support HDR and wide color gamut?
Yes. AVIF is built on the AV1 codec and supports HDR and wide color gamuts including Display P3 and Rec. 2020. For web display, this matters only when your source photo contains HDR data and the viewer's browser and display hardware both support it.
Will converting JPG to AVIF improve image quality?
Converting does not recover lost detail — JPG is already lossy, and that information is gone. AVIF can encode the remaining pixel data more efficiently, yielding a smaller file at similar quality, not a sharper image. Start from lossless source files to get the best AVIF results.
Is there a free tool to convert JPG to AVIF without uploading to a server?
Image Machine converts JPG to AVIF entirely in your browser — no file is ever sent to a server. It is completely free, requires no account, and adds no watermark. Upload your photo, run the conversion, and download the AVIF file in seconds.
