Convert JPG to AVIF
Free online JPG to AVIF converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert JPG to AVIF?
AVIF often beats JPG by 30–50% at similar visual quality, which is why performance-minded sites ship AVIF with fallbacks. Convert JPG to AVIF in the browser when preparing assets for modern CDNs and next-gen img srcsets.
Tips
- Encoding uses Squoosh/libavif in your browser (quality default 50 for size wins).
- Keep a JPG or WebP fallback for older clients that cannot display AVIF.
- Quality 40–55 shrinks photos; 70+ is for near-archival and often larger than a good JPG.
Frequently asked questions
How do I convert JPG to AVIF?
Drop your JPG file into the converter above, adjust the quality if needed, and click "Convert to AVIF". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the JPG to AVIF conversion lossless?
AVIF is a lossy format. Quality is controllable from 1–100% (default 50%); at recommended settings the result is visually close to the source for most photos.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my JPG files uploaded to your servers?
No. All JPG to AVIF conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
