Image Optimizer is useful in a variety of scenarios across different workflows:
Optimizing images for web performance and Core Web Vitals
Reducing image file sizes for e-commerce product photos
Preparing images for email campaigns with size limits
Use WebP or AVIF for photos, PNG for graphics with text, and JPEG for broad compatibility. Don't re-encode lossy formats multiple times.
Quality 80-85 is often the sweet spot — visually lossless but significantly smaller than 100% quality.
