Compression Artifact
Compression Artifact (Visual Distortion)
Compression artifacts are visible distortions introduced by lossy compression algorithms. Common artifacts include blockiness (JPEG macroblocks), ringing around sharp edges, color banding in gradients, and mosquito noise.
Teknik Detay
JPEG artifacts result from quantization of DCT coefficients, where high-frequency detail is discarded. Artifacts worsen at lower quality settings and accumulate with repeated saves (generation loss).

```javascript
// Image compression via Canvas
canvas.toBlob(
blob => console.log(`Size: ${(blob.size/1024).toFixed(0)} KB`),
'image/jpeg',
0.8 // quality: 0.0 (smallest) to 1.0 (best)
);
// WebP output (25-34% smaller than JPEG)
canvas.toBlob(cb, 'image/webp', 0.8);
```
