Worked Example
Example: a 5 MB photo from a phone is uploaded to a blog post and slows the page down. Resizing it to 1200 px wide and converting it to WEBP can reduce it to well under 200 KB while it still looks sharp on screen, which makes the page load noticeably faster.
Quick Reference Table
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG | Lossy | No | Photos |
| PNG | Lossless | Yes | Screenshots, logos |
| WEBP | Lossy or lossless | Yes | Websites |
| SVG | Vector | Yes | Logos and icons |
| HEIC | Lossy (efficient) | Yes | iPhone photos |
| AVIF | Lossy (very efficient) | Yes | Modern websites |
