WebP and AVIF are both modern image formats, but they should not be used in the same way on every website. The best choice depends on compatibility, file size, visual quality, image type and how much control your publishing workflow gives you.
Use WebP when you need the safest modern default
WebP is usually the best starting point for everyday web images. It works well for product photos, blog images, landing pages, thumbnails and most website assets where you want a smaller file without creating a complicated delivery setup.
For many teams, WebP is the practical balance: it can reduce file size, keep visual quality high and remain easier to support across common browsers, CMS tools and image pipelines.
Use AVIF when compression matters more than simplicity
AVIF can produce excellent compression, especially on large photographic images or content-heavy websites. The trade-off is that AVIF workflows can require more testing, more careful encoder settings and clearer fallback planning.
If your stack already supports AVIF reliably, it can be a strong option for performance-focused pages. If your workflow is simple or you are optimizing client websites, WebP is usually easier to roll out first.
Practical rule for production websites
- Choose WebP for broad, everyday website optimization.
- Choose AVIF when your site stack supports it and you can test output quality.
- Keep JPG or PNG only when compatibility, transparency or editing needs require it.
- Do not convert blindly: JPG to PNG can increase file size, and PNG is not always better for photos.
Recommended TinySharp workflow
Start with the WebP converter for most website images. Use AVIF only when you need advanced compression and know your website delivery path supports it. For existing JPG or PNG files that should remain in the same format, use compression rather than conversion.
