  • Export to multiple formats: CSS, Tailwind, SCSS, W3C tokens, Android, iOS
  • Wide-gamut Display P3 and CSS Color Level 4 support
  • Grain is rendered into the image at full resolution, not pasted on top, so it survives JPEG compression, scaling and print

  • Pay once, never auto-renews; no subscription required
  • Free tier is genuinely useful with 5 full-resolution 4K exports monthly
