Most online gif optimizer utilities require uploading your files to remote servers, exposing sensitive business or personal data to leakage, and throttle speeds with download queues. Toolchi is different. All scaling, cropping, and compression operations run strictly inside your browser tab utilizing canvas and CPU threads. Our workspace integrates a dynamic Web Speed Readiness Score to analyze page load suitability, and offers custom presets tailored for blog heroes (1200px), SEO previews, and social headers with 100% file privacy.
Toolchi offers high-performance Developer APIs for this tool's pipeline. Integrate image compression, PDF merge/split, SEO audits, and AI generation programmatically.
