  • image/webp: animation supported (*)
  • image/svg+xml: scaling supported (*)
  • image/bmp, image/jpeg, image/x-icon
  • image/png: all other image formats will be saved as PNG base-64
    (*) - when copy the base64 content and open in browser - Chrome
• Conversion from base-64 format to image formats (png/bmp/gif/...):
  • TIFF / GIF: Only first frame/page
