About Squeezy
Part of the runtime-hub.com ecosystem
Squeezy is a high-performance image compression tool that runs entirely inside your browser. No files are ever uploaded to any server. Everything happens locally, on your device, using modern Web APIs.
How it works
Squeezy uses the HTML5 Canvas API to decode, process, and re-encode images. Compression tasks are offloaded to a dedicated Web Worker thread, keeping the main UI thread free and responsive even during heavy batch operations.
For JPEG and WebP, we leverage the browser's native codec at configurable quality levels. For PNG, we offer conversion to smaller formats or canvas-based re-encoding.
Privacy by design
Your images never leave your machine. There are no analytics on image data, no backend processing, and no CDN caching of your files. Once you close the tab, everything is gone.
Technology
- Web Workers for non-blocking compression
- Canvas API + OffscreenCanvas for image processing
- FileReader API for secure local file access
- Blob + Object URLs for zero-copy downloads
- No external dependencies or frameworks
