About This Tool
Convert images to and from AVIF — the newest major image format, around 50% smaller than JPEG and 20% smaller than WebP at comparable quality. AVIF is supported by Chrome, Firefox and Opera, and partially by Safari; this tool lets you adopt it where it helps and convert AVIF downloads back to JPG or PNG for older software. Encoding happens in your browser via WebAssembly, so large files simply take a few seconds longer instead of being uploaded.
How to Use This Tool
- Drop your images — AVIF input or JPG/PNG/WebP you want to convert to AVIF.
- Choose the target format and, for AVIF output, a quality between 50 (small) and 85 (high fidelity).
- AVIF encoding is slower than JPEG: expect 2-5 seconds per photo; batch progress is shown per file.
- Download the results and test them in your target environment.
- Keep a JPG copy alongside AVIF if your audience includes older Safari versions.
Advantages & Use Cases
Cutting a hero image from 380 KB (JPEG) to 150 KB (AVIF) for a faster landing page, or delivering an image-heavy documentation site where every KB counts on mobile data. Converting AVIF stock assets back to JPG for clients using older design software is the second common flow.
Supported Formats & Recommendations
- JPG → AVIF at quality 60 often matches JPEG quality 85 visually at half the size.
- AVIF → JPG: universal compatibility; expect a size increase.
- AVIF → PNG for lossless editing needs.
- Animation: AVIF supports sequences, but for broad compatibility convert animations to WebP or MP4 instead.
How We Test This Tool
Each release converts a reference photo set and checks that AVIF outputs decode correctly in Chromium and Firefox, that 10-bit input does not posterize, that file size lands within 10% of the libavif reference encoder at the same quality, and that EXIF orientation survives conversion.

Frequently Asked Questions
Is AVIF supported everywhere?
Chrome, Edge, Firefox and Opera yes; Safari supports AVIF since version 16 but not all features. For a public website, serve AVIF with a WebP or JPG fallback — most CMS and CDNs do this automatically via
Why is AVIF encoding so slow compared to JPEG?
AVIF (AV1-based) tries far more compression possibilities per frame. The trade-off is much smaller files; encoding a photo takes seconds, not milliseconds.
Does AVIF support transparency?
Yes, including both full alpha and 10-bit HDR color, which makes it a modern replacement for both JPEG and 8-bit PNG.
