How do I save the highest-resolution images possible?

Current versions of Percolator support vector PDF export. For high-resolution bitmap export to your Photo Library, see the instructions below:

The export settings are available through the Image Settings menu (Tap ♥︎, then under Image, scroll left and select Settings)

  • Small: 1024 px on the longest side
  • Medium: 2048 px on the longest side
  • Large: 3072 px on the longest side
  • Original: The exported image is sized to the same size as the original source image (up to a maximum of 3584 pixels on the longest side, depending on which generation iOS device you have).
