Why Convert WebP to AVIF?
AVIF is built on the AV1 codec and targets superior efficiency:
- Smaller Files: Frequently 15–30% smaller than comparable WebP at similar quality.
- High Quality: Better detail retention at lower bitrates.
- Modern & Future-proof: Broad and growing browser support.
- Transparency: Full alpha channel support like WebP.
How to Convert WebP to AVIF Online
- Click Upload WebP and select your file.
- Wait for processing and optimization.
- Click Download AVIF to save the result.
Defaults balance fidelity and size for the modern web.
AVIF vs WebP Comparison
- Compression: AVIF generally achieves smaller files at similar quality.
- Transparency: Both support alpha channels.
- Animation: This tool outputs static AVIF (first frame only).
- Browser Support: AVIF is supported by current versions of major browsers.
Supported Limits & Formats
- Accepted input: WebP (
image/webp) - Maximum file size: 16 MB per file
- Output: AVIF (
.avif,image/avif) - Animation: First frame only
Troubleshooting
- Colors look different: Output is converted to sRGB for web consistency.
- File still large: Try a higher cqLevel (e.g., 34–36) or downscale before converting.
- Upload fails: Ensure
image/webpand ≤ 16 MB.
- Yes, it’s completely free with no watermarks or hidden charges.
- AVIF is supported by modern browsers (Chrome, Firefox, Safari, Edge). Provide WebP or JPG fallbacks for older versions.
- Results vary by image, but AVIF is often 15–30% smaller at similar visual quality.
- Yes. If your WebP has an alpha channel, the AVIF output preserves it.
- Animated WebP is converted as a static image using the first frame.
- You can upload images up to 16 MB per file.
AVIF is highly efficient but may render a bit slower on very old devices. For maximum compatibility, keep your original WebP as a fallback.
