orHow Client-Side Image Compression Works
Compressing images locally in the web client avoids uploading files to remote servers:
- Canvas Resizing: The browser reads the image file and draws its dimensions onto an HTML5 `
- Quantization Compression: Exporting the canvas context using `.toDataURL('image/jpeg', quality)` triggers the browser's native JPEG compression encoder. This drops high-frequency pixel variations to shrink byte weights.
