How to convert JPEG to AVIF
Drag and drop your JPEG files into the upload zone, or click to browse and select them from your device.
Click Convert to AVIF. The conversion runs in your browser when supported, with secure server fallback if needed.
Download each converted AVIF file individually, or use Download all after multiple files finish.
JPEG and AVIF - what's the difference?
AVIF: Choose AVIF when you want the smallest possible file size at good quality and the destination supports it. WebP: Choose WebP instead if broader compatibility is a priority — WebP has been supported in browsers longer than AVIF.
Why People Convert JPEG to AVIF
Convert JPEG files to AVIF online for free. AVIF is one of the most efficient image formats available, producing files typically 40–60% smaller than JPEG at comparable visual quality.
JPEG compression technology is decades old. AVIF, built on the AV1 codec, uses much more advanced compression and consistently produces smaller files at the same visual quality level. For web publishers with many JPEG images, converting to AVIF is a straightforward way to reduce page weight without changing how images look.
AVIF is now supported in all major modern browsers. Converting JPEG assets to AVIF is a practical web performance step for image-heavy sites, product galleries, and any context where bandwidth and load time matter.
Common situations where this helps
A website with many JPEG photos needs smaller delivery files to improve load times and Core Web Vitals scores.
A product image gallery needs to reduce file sizes for a better mobile experience without visible quality changes.
You are adopting modern image formats for a web project and want to convert existing JPEG assets to AVIF.
A JPEG image needs to be uploaded to a platform that accepts AVIF and benefits from its smaller file size.
Common problems and fixes
The browser or platform does not support AVIF.
AVIF is supported in Chrome, Firefox, Edge, and Safari 16+. For older Safari or legacy platforms, WebP or JPEG are safer choices.
The AVIF output has noticeable artefacts.
AVIF compression can be aggressive at low quality settings. Increase the quality setting to reduce artefacts while still achieving a smaller file than JPEG.
AVIF conversion is slow.
AVIF encoding is computationally intensive. Large files take longer, especially at high quality settings. Resize images before converting if speed is a priority.
