Does converting JPG to AVIF reduce image quality?

AVIF uses highly efficient lossy compression. At the default quality setting of 85, visual quality is essentially indistinguishable from the original JPG while achieving significantly smaller file sizes. Increase the quality slider for even less compression.

Why convert JPG to AVIF?

AVIF typically achieves 50% smaller file sizes than JPG at equivalent visual quality. For websites, smaller images mean faster load times and better Core Web Vitals scores. AVIF also supports transparency and HDR color, unlike JPG.

Can I convert multiple JPG files at once?

Yes — this tool supports batch conversion. Drop up to 25+ files at once, monitor per-file status, then download individually or as a single ZIP archive.

Which browsers support AVIF encoding?

Chrome 85+, Edge 85+, and Firefox 93+ all support AVIF encoding via the Canvas API. Safari has decode support (Safari 16.4+) but canvas encoding may vary. Use Chrome or Edge for best results.

Does my data get uploaded to a server?

Never. All JPG decoding and AVIF encoding happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your images never leave your device.

How It Works

Drop your JPG filesDrag multiple .jpg or .jpeg files onto the drop zone, or click Browse Files. Thumbnails generate immediately from the browser's native JPG decoder.

Set quality and click Convert to AVIFThe browser draws each JPG to an HTML Canvas and encodes it as AVIF using the Canvas API's toBlob('image/avif', quality) method.

Download your AVIFsDownload files individually or check "Download as ZIP" for a single timestamped archive containing all converted files.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. JPG files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for confidential photos, client images, or any files you prefer not to upload to third-party services.

Frequently Asked Questions

How much smaller will my AVIF files be?▼

Typically 40–60% smaller than the original JPG at equivalent visual quality. A 3 MB JPG photo might become 1–1.5 MB as AVIF at quality 85. Results vary by image content — photos with complex detail compress differently than simple graphics.

What quality setting should I use?▼

The default of 85 is recommended for most use cases — it produces excellent visual quality at significantly reduced file sizes. For web thumbnails or social media, 70–80 is often sufficient. Use 90–95 for print or archival purposes where maximum fidelity matters.
