The nexter/update-image-optimization ability updates the image optimization settings in Nexter Extension. You can configure the output format, quality mode, maximum dimensions, EXIF data handling, and processing behavior. Changes apply to future optimization runs. Existing images are not re-optimized automatically.

Key Takeaways

All parameters are optional. Only the fields you pass are updated.

Changing settings does not trigger re-optimization of already-processed images.

Use nexter/bulk-optimize-images after updating settings to apply the new config to existing images.

Use nexter/get-image-optimization to read current settings before making changes.

This ability ships with Nexter Extension (Free). If you do not have it installed, follow the guide on how to install and activate Nexter Extension first.
