Crochet Alpha
Pattern Generator
Draw your alpha square by square on a blank grid, or drop in a photo and let the generator build the chart. Either way you get a single crochet colorwork chart with the color counts written out row by row.

Built for Alpha Charts
Alphas are drawn as often as they are converted — both paths land on the same chart.
Start From an Empty Grid
Most alphas start as an idea, not a photo. Open a blank grid at the size you want, then place squares with the pencil, flood-fill regions, and drag straight lines for borders and lettering. Undo and redo the whole way. Nothing is uploaded and no account is needed to draw.
Or Convert Any Image
Have a reference — fan art, an album cover, a photo of your dog? Drop it in and the generator maps it onto the grid, picks the palette, and hands you an editable chart. Fix anything you don't like with the same drawing tools before you export.
Written Row Instructions
Every row is spelled out as color runs — "15 white, 3 black, 12 white" — and the reading direction alternates each row, because you turn your work at the end of every row. Row 1 is the bottom of the chart, so the finished piece isn't upside down.
Clean Color Blocks
A converted photo comes out speckled: single stray squares scattered through a color field. Each one is a color change for exactly one stitch. Confetti reduction merges them into the surrounding color so the chart reads as blocks you can actually crochet.
What Makes a Good Alpha Design
Alphas live on flat, graphic shapes: bold lettering, hearts, stars, checkerboards, cherries, flames, mushrooms, smileys, characters with a heavy outline. Anything that survives being drawn in solid blocks with no shading will read at stitch resolution. Fine gradients and small text will not — a letter needs to be at least 5 squares tall before it stays legible.
Grid width is stitch count, so it sets the size directly. A phone pouch or a small bag panel is around 30–50 stitches across, a crop top panel 50–80, a wall hanging 80–120. At a common worsted-weight gauge of 16 single crochet per 10 cm, a 60-stitch panel finishes about 37 cm wide. The dimensions readout updates while you drag the slider, so you can settle the size before you buy yarn.
Color count is the other decision that matters. Alphas are worked in single crochet with the colors you aren't using carried along inside the row, so every extra color adds thickness to the fabric. Four to six colors is the comfortable range for wearables and bags; a wall hanging can carry more because nobody has to wear it.
Drawing Your Own vs Converting a Photo
Drawing is the better path when the design is already a graphic — lettering, a logo, a symbol, pixel art you're recreating. You control every square, so there is nothing to clean up afterwards, and you can build the design at exactly the stitch count you want to work.
Converting is the better path when you're starting from a picture: fan art, a portrait, a photo. The generator does the hard part — choosing a limited palette that still looks like the original and snapping it to the grid — and then you tidy the result by hand. In practice most people do both: convert, then redraw the parts that matter.
