guide · WebP vs AVIF vs JPEG
Choose the right image format before you compress. WebP is a strong default, AVIF can be smaller, and JPEG remains useful for broad compatibility.
Quick answer
| Format | Best for | Transparency | Typical size | Main limit |
|---|---|---|---|---|
| JPEG | Photos and broad uploads | No | Medium | Larger than modern formats at similar visible quality |
| WebP | Modern web photos and mixed graphics | Yes | Small | Some older systems may reject uploads |
| AVIF | High compression for supported browsers | Yes | Smallest | Encoding and platform support vary more |
WebP usually gives a smaller result than JPEG while keeping good visual quality. It also supports transparency, so it can replace many PNG assets when your CMS or storefront accepts it.
For everyday web publishing, start with WebP at a balanced quality setting, then compare the result against the original image at the displayed size.
AVIF can produce very small files, especially for photographic or high-detail images. It is a good candidate for performance-sensitive pages, but output support and encoding speed can vary by browser.
Use AVIF when you control the delivery environment or have a fallback strategy. Do not assume every upload form or third-party platform will accept it.
JPEG is old, but it remains widely accepted. It is useful for email attachments, forms, product feeds and systems that do not yet accept WebP or AVIF.
If compatibility is more important than maximum compression, compress JPEG carefully and avoid repeated re-export cycles.
No. WebP is often smaller, but JPEG can still be better when an upload system requires it or when older compatibility matters.
No. AVIF is worth testing for size-sensitive pages, but support and export behavior vary. Keep fallbacks for important images.
