  • Daltonize accepts most common image formats. However, we recommend that you use PNG or JPEG format for uploading large images as these tend to transfer faster.
  • For PowerPoint slides, you can save all your slides as PNG images with "Save As..." and run Daltonize on each slide.
  • Uploading a large file may take a while - please be patient!
