What is Convert PNG to AVIF?
AVIF (AV1 Image File Format) is the newest entrant in the image compression landscape, leveraging the AV1 video codec to achieve unprecedented compression efficiency. Converting PNG to AVIF can reduce file sizes by 50% or more compared to PNG while maintaining equivalent visual quality and full transparency support.
AVIF is royalty-free and backed by the Alliance for Open Media, whose members include Google, Apple, Netflix, Amazon, and Meta. While browser support is rapidly growing (currently ~92% of browsers), AVIF represents the future of web image delivery with its HDR support, wide color gamut, and superior compression.
How to Calculate
- Drop your PNG file(s) into the converter or click to select them
- Adjust the quality slider (50-70% recommended for web use — AVIF is efficient even at lower settings)
- Click Convert to process — conversion happens instantly in your browser
- Download your AVIF file(s)
Key Benefits
- Files up to 50% smaller than PNG at the same visual quality — industry-leading compression
- Full alpha transparency support just like PNG
- HDR and wide color gamut support for future-proof image delivery
- Royalty-free format backed by Google, Apple, Netflix, Amazon, and Meta
- 100% private with client-side processing
Common Use Cases
- Maximizing website performance by using the most efficient image format available
- Preparing images for platforms and browsers that support next-generation formats
- Reducing bandwidth costs for image-heavy applications and content delivery networks
- Future-proofing image assets with a format designed for the next decade of web standards
- Delivering HDR images with wide color gamut for compatible displays
Key Terms Explained
- AVIF (AV1 Image File Format)
- A next-generation image format using AV1 video compression intra-frame encoding for superior efficiency.
- AV1 Codec
- A royalty-free video codec developed by the Alliance for Open Media that AVIF leverages for still-image compression.
- HDR (High Dynamic Range)
- A technology that expands the range of brightness and color an image can display, supported by AVIF but not PNG.
Pro Tips
- AVIF offers excellent quality even at lower quality settings — try quality 60-70% first for significant file savings
- Test AVIF compatibility with your target audience — approximately 92% of browsers currently support it
- Use the <picture> element with AVIF as the primary source and WebP or PNG as fallback for maximum compatibility
- AVIF encoding is more computationally intensive than other formats, but decoding is fast — ideal for delivered content
What is PNG?
PNG is a lossless image format supporting alpha transparency and millions of colors. It is widely supported but has less efficient compression than modern alternatives.
What is AVIF?
AVIF is a next-generation image format offering industry-leading compression efficiency, HDR support, wide color gamut, and alpha transparency. Founded by the Alliance for Open Media.
Frequently Asked Questions
How does AVIF compare to WebP?↓
AVIF typically achieves 30-50% better compression than WebP at the same quality level. It also supports HDR and wider color gamuts that WebP does not.
Is AVIF supported in all browsers?↓
AVIF is supported in approximately 92% of browsers including Chrome, Firefox, Safari 16.4+, and Edge. Legacy browsers require a fallback format.
Does AVIF support transparency?↓
Yes. AVIF supports full alpha channel transparency, identical to PNG and WebP.
Is AVIF slower to encode?↓
AVIF encoding requires more computation than JPEG or PNG. However, your browser handles this efficiently, and the decoded images display just as fast as other formats.
Should I convert all my PNGs to AVIF?↓
For web distribution, yes — AVIF provides the best compression available. For editing workflows, keep originals in PNG or a lossless format.
Is this free and secure?↓
Yes, completely free. All processing happens in your browser — files never leave your device.
