Step 2 · Stitch type

Step 3 · Grid size

Stitches along the longest side — the other side follows your photo’s shape. 80 is the sweet spot for most photographs.

Step 4 · Number of colors

More colors = richer image, more yarn changes per row.

Step 5 · Yarn brand preference

Step 6 · Chart cleanup

Smooth chart for stitchingRemoves single-stitch specks (“confetti”) so you never change color for one lone stitch. Recommended.

One tool, many names

Graphgan generator, crochet graph maker, photo-to-chart converter.

Crocheters call this tool different things — a graphgan generator, a crochet graph maker, a picture-to-crochet-grid converter, a crochet pattern creator, a C2C pattern generator. They all mean the same job: turn an image into a chart you can actually stitch, square by square. StitchingLab does that for tapestry crochet, corner-to-corner (C2C), filet crochet, cross-stitch, and knit colorwork — and unlike most tools, the written row-by-row instructions, the chart editor, and the row tracker are free. Prefer to start from a blank grid? Use the chart designer, or compare every generator honestly on our tested roundup.
