Why Compress to 100KB?
100KB is a common upload limit for job portals, HR systems, and university application forms. It strikes the balance between acceptable visual quality and a small enough file for most online form validators. Images at 100KB also load quickly on mobile networks and reduce bandwidth costs on content-heavy websites.
Our tool runs entirely in your browser using the HTML5 Canvas API. Your images are never sent to any server — compression happens locally on your device, so your files stay 100% private.
