Quality Slider Explained

  • • 1–100% — Controls the quality parameter in canvas.toBlob('image/gif', quality/100)
  • • Higher % → better visual quality + larger file size
  • • Lower % → smaller file, but more color banding / dithering
  • • GIF is always palette-based (256 colors max) — quality affects how aggressively colors are quantized
  • • Live size estimate shown (approximate — final size after real conversion may vary slightly)
