Why Use Image Compressor?
You should try Image Compressor for a quick, private way to re-encode photos as jpg, webp or png at a quality you choose. 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.
