Used —

Same seed always produces a byte-identical PNG. Leave it empty and each Generate rolls a fresh one.

Symmetry

Larger scale means bigger shapes; octaves add fine detail. Ridged creases the noise into veins, billow puffs it into clouds. Warp bends the sampling with a second noise field for marble and wood grain — it disables tiling. Symmetry folds the image into a motif.

Edges & texture

Edges

Levels 5

Seamless tiling

Dither

Contour lines only

Sharp quantizes the field into flat regions; levels sets how many. Dither trades banding for a fine stipple. Contour draws only the band boundaries, turning any field into a topographic map.

Color

Harmony

Hue 0–360

Sat % 0–100

Light % 0–100

Hue shift 0°

Curve

Strength 1.00

Ramp

Grayscale only

Harmony picks hues by color-wheel angle, so the palette looks chosen rather than sampled; it overrides the hue sliders. Hue shift rotates hue with lightness — the heatmap trick.

Pixel bias

Mode

Strength 0.50

Weighted makes a few colors dominate instead of every color appearing equally often.

Animation

Frames 12

Delay ms 80

Drift 0.06

Frames travel a closed circle through the noise, so the GIF loops with no visible jump. Perlin and cells only. Past about 0.15 drift the motion stops reading as one moving field.

Export

Save at

Save-at upscales with hard pixel edges, so the file stays PNG-8 and blocky rather than blurred.

Palette import

An imported palette replaces the generated colors and is used in the order given.

Presets

Presets carry every setting except the seed, so a shared preset reproduces the style, not one exact image.

Randomize

Click 🔓 beside any setting to keep it fixed while randomizing.

Press Generate to make an image.

Most frequent — click a swatch to lock it

Most different

Added colors lock into the strip, so they survive Generate and are included when you save the palette.
