HTML5 Canvas Image Pipeline
How image frames are decoded and re-encoded locally:
// 1. Create offline Canvas context in memory
const canvas = document.createElement("canvas");
const ctx = canvas.getContext("2d", { willReadFrequently: true });
// 2. Decode and render image bitmap locally
ctx.drawImage(sourceBitmap, 0, 0, targetWidth, targetHeight);
// 3. Export high-quality blob directly to local disk
canvas.toBlob((blob) => triggerLocalDownload(blob), "image/webp", 0.92);Key Features & Instant Benefits
