Architectural FAQs: Client-Side Compression
How does offline compression work?
We utilize the HTML5 Canvas API natively built into your browser's V8 engine. The image is drawn onto an invisible canvas in your local memory. When you adjust the slider, the browser recalculates the compression algorithm and exports a new binary blob without ever communicating with a remote server.
What is "Canvas Bloat"?
If you upload a heavily optimized image (like a 30KB icon) and run it through a standard web canvas, the browser's generic encoder might output an 80KB file. Most web tools hide this. Our transparency engine calculates the final byte-size in real time, alerting you instantly if the math is not in your favor.
