Images are still the single biggest contributor to page weight on most sites. A handful of changes usually recover most of the available savings.
1. Resize at the source
Never ship a 4000px photo into a 400px card. Generate the exact dimensions each layout needs.
2. Convert to a modern format
Switching JPEG to WebP or AVIF alone typically saves 25–50% with no visible difference.
3. Set a sane quality ceiling
Quality 100 is rarely necessary. 75–85 is usually indistinguishable on photographic content and meaningfully smaller.
4. Serve responsive sources
Pair correctly-sized images with srcset so phones don't download desktop-sized files.
5. Cache processed output at the edge
Once an image is transformed, it shouldn't be recomputed on every request — cache it close to the reader.
Running all five through a single API call is exactly what pixpoo's transform endpoint is for.
