Upload any image, adjust the threshold to keep the details you want, then invert colors if needed. Export a clean black and white PNG and use it as the starting image in the Deltarune Prophecy Maker.
A monochrome image consists of only two colors - typically black and white. Each pixel in the image is converted to either black or white based on its brightness and the threshold value you set.
The threshold (0-255) determines which pixels become black or white. Pixels brighter than the threshold become white, while darker pixels become black. Adjust it to find the best balance for your image.
The invert option switches black and white in your image. This is useful when you want to reverse the colors of your monochrome result.
The converter supports common image formats including PNG, JPEG, GIF (first frame only), and BMP. For best results, use high-contrast images with clear details.
Monochrome images are perfect for pixel art, retro-style graphics, logos, and creating dramatic visual effects. They're also ideal for the Deltarune Prophecy Maker's art style.
Upload your source image, move the threshold until its main shapes are clear, and use invert colors if the light and dark areas are backwards. Export the PNG, then upload it to the Deltarune Prophecy Maker to build a custom prophecy panel.
Yes! You can freely adjust the threshold and invert colors even after uploading your image. Experiment with these settings to achieve the perfect look for your prophecy panels.
