- For JPG, WebP, AVIF and image-to-PDF output: higher keeps more detail but makes a bigger file; 60–80 suits most photos. Documents (Publisher, XPS, EPS…) become PDFs with every page and sharp text, with no quality setting.

- For WebP and AVIF output: keeps every pixel exactly (best for logos, graphics and transparency) at the cost of a larger file.
- 背景の塗りつぶしカラーピッカー
- For JPG, BMP and image-to-PDF output, which can’t store transparency: the colour that fills transparent areas (white by default).
