AVIF delivers stunning quality at tiny file sizes — but should you actually use it? Here's the complete, honest 2026 breakdown.
AVIF is the newest major image format of the modern web. On paper, the numbers are extraordinary — up to 50% smaller than JPG with better quality, and 20-30% smaller than WebP. In practice, the situation is more nuanced. Here's everything you need to know.
AVIF stands for AV1 Image File Format. It was developed by the Alliance for Open Media (AOM) — a coalition that includes Google, Netflix, Apple, Microsoft, Mozilla, Amazon, and others — and officially released in 2019. AVIF uses the AV1 video codec's compression technology applied to still images.
The AV1 codec was specifically designed to surpass the compression efficiency of older standards like VP9 (used by WebP) and HEVC (used by HEIC). The result is an image format with genuinely exceptional compression — the best available in 2026 for most use cases.
| Image (Same Quality) | JPG | WebP | AVIF |
|---|---|---|---|
| Portrait photo (2000×3000) | 2.4 MB | 1.7 MB | 1.1 MB |
| Product photo (800×800) | 145 KB | 98 KB | 68 KB |
| Landscape hero (1920×1080) | 890 KB | 620 KB | 410 KB |
| Text-heavy screenshot | 320 KB | 195 KB | 140 KB |
AVIF consistently delivers 40-55% smaller files than JPG and 25-35% smaller than WebP at equivalent visual quality. These aren't theoretical numbers — they're from independent benchmarks run on thousands of real-world images.
AVIF's compression is particularly impressive in specific areas where older formats struggle:
| Browser / Platform | AVIF Support |
|---|---|
| Chrome 85+ | ✓ Full support |
| Firefox 93+ | ✓ Full support |
| Safari 16+ | ✓ Full support (since 2022) |
| Edge 121+ | ✓ Full support |
| iOS 16+ | ✓ Full support |
| Android Chrome | ✓ Full support |
| Windows Photo Viewer | ✗ Not supported |
| Older browsers (pre-2022) | ✗ No support |
As of 2026, AVIF has broad modern browser support. However, if you're serving images to users who might have older devices or browsers (enterprise users on locked-down Windows systems, for example), you should provide a JPG fallback.
AVIF has one significant practical problem: it's extremely slow to encode. Compressing an image to AVIF can take 10-100x longer than JPG or WebP. For a single photo this might mean 2-3 seconds instead of 0.05 seconds. For a website with 10,000 product images, this becomes a serious infrastructure challenge.
AVIF decoding (displaying the image) is fast — comparable to JPG and WebP. The slowness is only in the encoding/compression step, which happens once when you prepare images for your website.
In 2026, AVIF is worth using if:
Stick with WebP if:
AVIF files can't be opened by most older software — they'll just show an error. If you receive an AVIF file and need to use it in Photoshop, email it, or print it, you need to convert it to JPG first.
PNGtoJPG supports AVIF to JPG conversion entirely in your browser — no software installation, no upload, completely free. Simply drop your AVIF file in and download the JPG.

The trajectory is clear — AVIF is the technically superior format and adoption is growing rapidly. Major platforms including Netflix (for thumbnails), YouTube, and Amazon already serve AVIF to supported browsers. As encoding hardware acceleration improves and encoding speed increases, AVIF's remaining weakness is being eliminated.
Prediction: by 2027-2028, AVIF will be the standard web format for new content, with WebP remaining common for older content and compatibility scenarios, and JPG remaining universal for sharing and archiving.
AVIF is the most impressive image format available in 2026 — smallest files, best quality, and growing support. For cutting-edge websites targeting modern browsers, it's the right choice. For compatibility-first scenarios, WebP remains the practical middle ground. For universal sharing and printing, JPG remains king.
