FX — dither, ASCII and LED tools for images and video

FX renders images and video in your browser using one of three modes: blue noise dithering, ASCII art, or an LED dot matrix. Processing runs entirely on your device — nothing is uploaded. Export stills as PNG and video as MP4.

• Blue Noise: Grainless blue-noise dithering
• ASCII: Glyph-based ASCII art
• LED: Red-to-white LED dot matrix
