Why convert JFIF to GIF?
- GIF is supported far more widely than JFIF, so the file is easier to open, share and upload.
- GIF is made for short animations, stickers and flat-colour graphics.
What to expect when converting JFIF to GIF
- GIF shows at most 256 colours per frame, so photos and gradients are dithered and may show banding.
- Your original JFIF file isn’t changed: you download a new GIF copy.

- 品質スライダーレンジ: 20–100 · デフォルト: 90
- 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.
- ロスレスモードオン/オフ
- 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).
