About Resize20KB
Empowering users worldwide with fast, free, and secure client-side image compression.
Our Mission
We believe that simple tasks should not require complex software, subscriptions, or compromising your privacy. Millions of job applicants, students, and citizens worldwide face strict file size limits when uploading documents and photos to portals.
Our mission is to make document preparation stress-free by offering a high-fidelity, instantaneous compressor that matches file size guidelines (like exactly under 20KB) in one click.
Privacy First
Unlike traditional online compression websites, we do not upload your images to any remote servers. All computation, resizing, and optimizations are performed in your local browser using client-side Canvas APIs. Your photos never leave your device.
AI-Optimized Quality
Our binary-search engine analyzes pixels locally to select the optimal JPEG quality scaling ratio. It strikes the perfect balance between compression rates and visual clarity, so text remains legible and faces remain sharp.

- Universal Compatibility: Fully responsive code works flawlessly on iOS Safari, Android Chrome, and modern desktop browsers.
