Free image tools for the web
Use our online WebP converter to turn JPEG, PNG, or GIF files into smaller WebP images — ideal for faster page loads and better Core Web Vitals. Our free image resizer lets you set width, height, and fit modes (cover, contain, fill) and download the result immediately. Everything runs in your browser; Spronta does not add watermarks or require an account for these tools.
When you are ready to automate format conversion, resizing, and CDN delivery for your app, see how Spronta Images works in production.
