AVIF (AV1 Image File Format) is based on AV1 video encoding technology, offering the highest compression efficiency currently available. It significantly reduces file size compared to traditional formats, with compression effectiveness notably superior to JPEG and WebP. This tool uses the browser's native API for encoding; please ensure you're using the latest browser version. Supports professional features like 10-bit color depth, HDR, and wide color gamut.
AVIF encoding support:
• Chrome 85+: Full support
• Firefox 93+: Full support
• Edge 90+: Full support
• Safari 16+: Supported on macOS 12+ and iOS 16+
Note: While mainstream modern browsers support AVIF, some older versions and systems may not. Providing fallback formats like JPEG or WebP is recommended for compatibility.
AVIF encoding characteristics:
• Speed: 5-10 times slower than JPEG/WebP
• Quality: Smallest file size at equivalent visual quality
• Quality parameter: 0-100, higher is better
• Recommendation: Quality 60-80 suits most purposes
Due to local processing, large images may take longer; please be patient. The browser may display "Page not responding," which is normal.
Professional features of AVIF:
• 10/12-bit color depth: smoother color transitions
• HDR support: preserves high dynamic range information
• Wide color gamut: Display P3, Rec.2020
• Color profile: automatically retains original color space
Note: These advanced features require the source image to support them; converting from a regular JPEG won't add color information.
Due to the high complexity of AVIF encoding:
• Large images (>4000px) may fail
• Test with small images on mobile devices
• Batch processing may cause out of memory
• Some browsers may crash
• Test parameters with small images first
• Save the original image in case conversion fails
These are browser technology limitations, not tool issues.
Q: When to use AVIF over WebP?
A: When targeting users with new browsers who prioritize file size.
Q: Why is conversion so slow?
A: AVIF uses complex video encoding technology, requiring significant computation.
Q: How to speed up conversion?
A: Reduce resolution, use lower quality values, avoid batch processing.
Q: Does it support transparency?
A: Yes, automatically preserves Alpha channel from PNG/WebP.
Q: What if it fails?
A: Try smaller images or use other formats.
