Contrast comes first
The default palette is intentionally limited to two sampled colors, preserving motif logic instead of photographic noise.
Mosaic crochet pattern generator
Reduce an image to a bold two-color chart.
Find the structure inside a photo or motif. The default two-color palette keeps the graph aligned with the high-contrast logic of mosaic crochet.

Yarn color & cell list
Clarity through reduction
Find the rhythm inside the picture.
Two colors and deliberate cleanup turn photographic information into a motif that can survive row-by-row crochet logic.
See the motif as cells
A square chart makes repeats, symmetry, and negative space easier to inspect before translating them to stitches.
Remove accidental single cells
Confetti cleanup closes tiny specks that are unlikely to produce a useful mosaic-crochet mark.
Designed for contrast
Turn the subject into a motif, not a noisy photograph.
Mosaic crochet works through graphic separation, rhythm, and row logic rather than continuous tone.
Begin with two colors
Two yarns make the chart easier to interpret and fit many overlay mosaic techniques. Add a third only when it represents a deliberate structural layer.
Crop for a recognizable silhouette
Faces and scenery need aggressive simplification at two colors. A tight crop, clean lighting, and a distinct subject-background boundary give the best starting graph.
Treat the output as a design grid
The tool does not infer drop stitches or technique-specific symbols. Use the grid to author the final row instructions for your chosen mosaic method.
Good to know
Clear answers,
before you start.
Why does the generator default to two colors?
Many mosaic crochet designs rely on a strong two-color relationship. It produces a clearer motif and fewer ambiguous stitch decisions.
Can I use more than two yarn colors?
Yes, up to six on this page, but extra colors can complicate the row logic and reduce the bold mosaic effect.
Does the PNG contain overlay mosaic symbols?
No. It is a clean color-cell graph, not technique-specific written or symbol instructions.
What type of image works best?
Logos, silhouettes, line art, and subjects with a simple background work better than low-contrast photographs.
Should I turn dithering on?
No for most mosaic crochet. Dithering creates alternating cells that are difficult to interpret as a clean motif.
Will my motif be stored online?
No. Your image and generated chart stay in the browser.
