Hi! I’d like to share CRT Retro Filter, a free Aseprite extension that renders your pixel art through the lens of a classic CRT display.

What it does

  • 12 independent filters: Scanlines, Screen Curvature (convex/concave), Chromatic Aberration, Bloom/Glow, Vignette, Noise, Color Temperature, Pixelation, RGB Phosphor Mask (grille/shadow/slot), Horizontal Ripple, Interlacing Jitter, Phosphor Persistence
  • 9 built-in presets: Classic Arcade, 80s Computer, Broadcast TV, Subtle Retro, CRT Monitor, VHS Tape, Trinitron, Pixel Perfect, Heavy Glitch
  • Real-time preview with change detection, plus before/after compare (hold the mouse button to peek at the original)
  • Preset Strength slider — dial the overall effect from 0% to 100%
  • Selection support — apply only inside the current selection
  • Apply to All Frames — process a whole animation in one undo step
  • Duplicate-layer option, custom presets, one-click Randomize, Quick Apply
  • Fully bilingual English / 中文 interface
