A larger image file does not always look better. Oversized sources slow loading, while excessive compression harms detail; assess quality and dimensions together.
Practical steps
- Prepare images for their rendered display size.
- Choose WebP and alternatives after visually checking quality.
- Declare dimensions and lazy-load images below the fold.
Define the scope
Improve technology while preserving working functionality. Document configuration and rollback first, considering files, databases and external connections together.
How to check the result
Check changes in a separate environment. Try critical pages and forms on real devices, inspect logs and publish only after successful validation.
A common mistake
Do not damage content or functionality to raise a score. Local success does not prove hosting and email providers behave identically.
Example application
For example, smaller images can load faster, but unreadable product detail requires rebalancing dimensions and compression. Assess both technical and visual results.
