Why Trust ToolOnWeb for Image Compression?
Unlike many other online converters that upload your files to a remote server, ToolOnWeb operates entirely in your browser.
100% Private & Secure. Your photos never leave your device. The compression happens locally using your computer’s processing power. This means we cannot see, store, or share your images. It is the safest way to compress sensitive or personal photos.

Why You Should Optimize WebP Files
WebP is already a modern, efficient format developed by Google, but raw WebP files can still be large. Compressing them offers significant benefits:
- Improve Core Web Vitals: Smaller images load faster, improving your Largest Contentful Paint (LCP) score, a key Google ranking factor.
- Save Bandwidth: If you host a website, serving smaller images reduces your bandwidth costs and saves data for your mobile visitors.
- Better User Experience: Users are likely to bounce from a site that takes more than 3 seconds to load. Optimized images keep them engaged.
