Why Use Image Optimization Scanner?

You should try Image Optimization Scanner for a quick, private way to find optimization opportunities in html. Processing happens in your browser and files are never uploaded; the few tools that need an outside service say so on the page.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
