What is Convert JPEG to AVIF?
JPEG has served the web faithfully for three decades, but its compression technology is far from optimal by modern standards. AVIF delivers 50% better compression than JPEG at equivalent visual quality, supports HDR and wide color gamut, and adds transparency capabilities that JPEG cannot provide.
Converting JPEG to AVIF is one of the highest-impact optimizations available for image-heavy websites. The format's efficiency means faster page loads, lower bandwidth costs, and better user experiences — particularly on mobile networks where every kilobyte counts. AVIF achieves this by leveraging the AV1 video codec's intra-frame compression techniques.
How to Calculate
- Drop your JPG file(s) into the converter or click to select them
- Adjust the quality slider (50-70% recommended — AVIF maintains quality 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 JPEG at the same visual quality — the best compression available
- Transparency support that JPEG cannot provide — for overlays, logos, and design elements
- HDR and wide color gamut support for compatibility with modern displays
- Royalty-free format backed by major technology companies
- 100% private with client-side processing
Common Use Cases
- Optimizing product images, photographs, and media assets for maximum web performance
- Reducing CDN bandwidth costs by 40-50% without sacrificing image quality
- Preparing images for modern web platforms and content delivery networks
- Future-proofing image collections with the next-generation format standard
- Improving Core Web Vitals scores through dramatic reductions in Largest Contentful Paint times
Key Terms Explained
- AVIF
- The AV1 Image File Format uses intra-frame encoding from the AV1 video codec to achieve superior still-image compression.
- Compression Efficiency
- Measured as the file size achieved at a given quality level. AVIF is the most efficient widely-supported image format as of 2025-2026.
- Alliance for Open Media
- The consortium behind AV1 and AVIF, including Google, Apple, Netflix, Amazon, Meta, Microsoft, and Mozilla.
Pro Tips
- AVIF quality 60-70% frequently matches or exceeds the visual quality of JPEG at 85-90% while being half the size
- Always test with your specific images — transparent areas, fine text, and sharp edges behave differently at various quality levels
- AVIF's compression advantage is most dramatic for photographic content, less so for graphics with large uniform areas
What is JPEG / JPG?
JPEG has been the web's standard photographic format since the 1990s, using lossy compression optimized for smooth tonal variations in photographs.
What is AVIF?
AVIF is a next-generation image format that delivers 50% better compression than JPEG, supports HDR and transparency, and is backed by the major browser vendors.
Frequently Asked Questions
How much will AVIF reduce my file sizes?↓
Compared to JPEG at the same quality, AVIF reduces file sizes by 40-50%. A 500KB JPEG photograph can become a 250-300KB AVIF with no visible difference.
Does AVIF support lossless compression?↓
Yes, AVIF supports lossless mode. For maximum compatibility, lossy AVIF at a high quality setting is usually the best approach.
Is AVIF compatible with my CMS or CDN?↓
Most modern CMS platforms and CDNs support AVIF. Check your provider's documentation for specific support details.
What is the browser support for AVIF?↓
Approximately 92% of browsers support AVIF as of 2026. Provide JPEG fallbacks for complete coverage.
Can AVIF be used for print?↓
AVIF is primarily designed for web use. For print, TIFF or high-quality JPEG are the standard choices.
Is this free and secure?↓
Yes, completely free. All processing happens client-side — files never leave your device.
