The Tools

Five creative tools, zero uploads

Part of ImgScale's suite of free browser-based image tools. Everything runs on your device.

Pixel Art Converter

Turn any photo or animated GIF into authentic, high-resolution pixel art. Uses a proper pipeline: progressive area-average downscaling → median-cut color quantization → optional dithering → nearest-neighbor upscaling. Six built-in retro palettes: Game Boy, PICO-8, NES, CGA, 1-bit, and Auto.

  • Animated GIF support — every frame pixelated with a unified palette
  • 6 retro palettes + Auto (median-cut, 2–64 colors)
  • 3 dithering modes: None, Floyd–Steinberg, Ordered (Bayer)
  • Before/after compare, sprite outline, noise cleanup, pixel grid
  • Export PNG at 1×, 4×, 8× or auto; animated GIF with timing

GIF Speed Changer

Adjust any animated GIF's speed with a live preview that updates instantly. Drop frames (½, ⅓, ¼) to cut file size while keeping total duration identical — dropped frame timing is redistributed to surrounding frames. Reverse the entire animation with one toggle.

  • Live real-time preview at the adjusted speed
  • Speed 0.25× to 4× with one-click presets
  • Frame drop ½, ⅓, ¼ — timing preserved, size dramatically reduced
  • Reverse playback toggle
  • Re-encodes with original transparency intact

Image to ASCII Art

Convert any photo into text art using brightness-to-character mapping. Classic terminal aesthetic or colored ASCII where each character takes its source pixel's color. 4 character sets plus custom ramp input. Exports as text, .txt, or PNG with dark/light/transparent background.

  • 4 character sets: Classic, Detailed (67 levels), Blocks ░▒▓█, Mono10
  • Custom ramp input — type any characters dark-to-light
  • Colored ASCII mode — full color in canvas output
  • Width 40–220 columns, brightness invert, live preview
  • Export: copy text, .txt, PNG (3 background options)

Color Palette Extractor

Extract dominant colors from any image using median-cut quantization. Each color's percentage is a real pixel-count measurement, not an estimate. Export to HEX, CSS custom properties, SCSS, JSON, or Tailwind config. Download a labeled palette strip PNG for mood boards.

  • Extract 3–16 dominant colors with real % measurements
  • Sort by dominance, hue, or luminance
  • Click any swatch to copy HEX instantly
  • 5 export formats: HEX, CSS, SCSS, JSON, Tailwind
  • Palette strip PNG for mood boards

Photo Border & Frame

Add a professional frame to any photo in seconds. Four styles: solid color, two-color gradient, polaroid with optional caption, or soft drop shadow on colored or transparent background. Size and roundness are percentage-based so they scale correctly at any resolution.

  • 4 styles: Solid, Gradient, Polaroid, Drop Shadow
  • Percentage-based size and roundness — scales at any resolution
  • Polaroid captions in Space Mono font
  • Shadow strength + transparent background export
  • High-res lossless PNG export up to 1800 px

Why PixelLab

Creative tools built the ImgScale way

Nothing uploaded

Like all ImgScale tools, PixelLab processes everything in your browser. Your images never leave your device. Open DevTools → Network to verify: it stays empty.

Instant results

No server queue. No upload time. Your own CPU and GPU do the work the moment you drop an image — results in milliseconds to a few seconds.

🆓

Completely free

No watermarks, no usage limits, no account. All five tools are fully featured and free. That's it.

Actually high quality

Real algorithms: median-cut quantization, Floyd–Steinberg dithering, area-average downscaling, perceptual color distance. Not just CSS filters.
