Use the right format
Modern formats such as WebP and AVIF are much smaller than JPEG or PNG at the same visual quality.
Most hosting setups and plugins can convert images automatically.
A useful starting point
Sort your media library by file size. The ten largest images are often responsible for most of the weight.
Serve the right size
Uploading a 4000-pixel photo for a 600-pixel space wastes bandwidth on every visit. Resize images to the largest size they will actually display.
Responsive image settings let browsers pick the best version for each screen.
Load images only when needed
Lazy loading delays images further down the page until the visitor scrolls near them, so the first screen appears faster.
Keep your main hero image loading immediately so it does not delay the first impression.
Your practical checklist
- Convert images to WebP or AVIF.
- Resize images to their display size.
- Turn on lazy loading below the fold.
- Compress images before uploading.
- Check page weight after the changes.
