Requires macOS 11+ or Windows 10+.
Nine categories of algorithms, each with adjustable sliders. Every change previews instantly. Processing runs in a background thread so the UI never freezes.
- Error Diffusion /18 algorithms including Floyd-Steinberg, Atkinson, Jarvis-Judice-Ninke, Stucki, Burkes, Sierra variants, and more
- Ordered / Bitmap /13 algorithms including Bayer matrices (2x2 through 16x16), clustered dot, dispersed dot, and diagonal ordered
- Halftone /4 styles: circle, line, diamond, and ellipse
- Modulation /15 algorithms including blue noise, FM screening, PWM, Riemersma, wave dither, spiral, and moiré
- Pattern /9 algorithms: crosshatch, lines (horizontal/vertical/diagonal), diamond, hex grid, brick, zigzag, triangle grid
- Glitch /8 algorithms: data corruption, pixel sort, displacement, scan line glitch, bit shift, channel shift, block glitch, VHS tracking
- Waveform / CRT /4 modes including RGB waveform glitch and CRT scanline
- JPEG Glitch / Chromatic /4 effects: JPEG glitch, chromatic aberration, scan line offset, artifact modulation
- Basic /Black & White, grayscale (4-shade, 8-shade)
- Retro /Game Boy, CGA, Commodore 64, NES, Apple II, ZX Spectrum, PICO-8, MSX, Teletext
- Handheld /GBA, Virtual Boy, Nokia 3310, Game Gear, WonderSwan, Atari Lynx
- Contrasts /Amber monitor, green phosphor, blue terminal, sepia, neon, vaporwave, cyberpunk, pastel, earth tones, and more
- Seasonal /Halloween, ghost, pumpkin, blood moon
- Thermal /FLIR Iron, rainbow, white/black hot, arctic, lava, medical
- Custom /build your own palette with a visual color editor
Full-scene simulations that transform your image into something entirely different:
- Thermal / FLIR /heat-map visualization with multiple palettes, temperature readouts, crosshair targeting (free)
- Night Vision /phosphor green with noise, vignette, and HUD overlay (Pro)
- Ultrasound /medical imaging simulation with scan modes and artifacts (Pro)
- Oscilloscope /CRT phosphor display with 5 modes, 7 phosphor types, beam physics, graticule, and HUD (Pro)
- Satellite /orbital imagery with map overlays and coordinate grids (Pro)
- Blueprint /technical drawing style with grid lines and annotations (Pro)
- Forensic Camera /evidence documentation with 8 scene profiles, markers, date stamps, and body cam overlays (Pro)
- Redacted Document /classified document simulation with redaction bars, stamps, and paper aging (Pro)
- Datamosh /frame corruption and glitch effects (Pro)
Special effect: Blueprint
Dial in the look before dithering: brightness, contrast, blur, sharpen, gamma, noise, denoise, invert. Small adjustments here produce dramatically different results.
- Epsilon Glow /CRT-style bloom on dithered dots
- Star Effect /4/6/8-point directional light spikes
- Glow threshold + color tint control
Dither entire videos frame-by-frame with real-time preview. Export to MP4 with audio preserved.
- PNG export with transparency support
- JPG and SVG vector export (Pro)
- Video export /MP4 with preserved audio (Pro)
- Batch processing /dither entire folders at once (Pro)
- Copy to clipboard (Pro)
- Compare view /before/after split slider
- Presets /save, load, and share your settings
- Undo/Redo with 50-step history
- 7 UI themes /Dark, CRT Green, Amber, Game Boy, Pink, Vaporwave, Light
- Keyboard shortcuts for everything
