FORMAT GUIDANCE
When to convert JPG to AVIF
AVIF can reduce the download size of photographic JPG files for modern websites and applications. Because the JPG source is already compressed, the useful goal is a smaller file with no distracting additional artifacts—not an increase in image quality.
Start around 75–82% quality and keep the original dimensions. Compare faces, fine textures, text and gradients before lowering the setting further.
AVIF encoding can take longer, and converting from JPG cannot restore detail previously removed by JPG compression. Keep the original for editing and older software.
JPG vs AVIF
| Consideration | JPG | AVIF |
|---|---|---|
| Compression | Lossy photo compression | Efficient modern compression |
| Transparency | Not supported | Supported by the format |
| Typical web size | Compact | Often smaller at similar visual quality |
| Compatibility | Nearly universal | Modern browsers and applications |
JPG to AVIF questions
What AVIF quality should I use for a JPG?
Start between 75% and 82%. Compare detailed areas at full size and lower the setting only when the extra file-size saving is worth the visual difference.
Will JPG to AVIF improve image quality?
No. AVIF may store the image more efficiently, but it cannot recreate detail that was already removed when the JPG was created.
Why does AVIF conversion take longer?
AVIF uses more complex encoding than JPG or WEBP. The additional processing happens locally in your browser and can produce a smaller download.
