Why convert TIFF to AVIF?

  • AVIF files are usually smaller than TIFF for the same picture, so pages load faster and uploads finish sooner.
  • Transparent areas stay transparent: AVIF supports smooth, partial transparency just like TIFF.
  • AVIF is made for the smallest high-quality images for websites and apps.

What to expect when converting TIFF to AVIF

  • AVIF uses lossy compression by default; raise the quality or switch on lossless in Settings for a closer copy.
  • 複数ページのTIFFは最初のページのみが変換され、CMYKの印刷色は標準のRGBになります。

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.
