Crochet Pattern Maker
Draw a graph, or turn a photo into one. A colored grid you can actually work from — with per-color block counts, built-in yarn palettes and a printable chart. Free, in your browser, no signup.
One grid, most of the graph-worked crochet you'd want
Almost every charted crochet blanket comes down to the same thing: a square grid where one cell is one unit of your work. What that unit is called changes with the technique — a block in C2C, a stitch in tapestry, a square in filet — but the chart is the same object. So the editor makes the chart, and you work it however your technique says to.
C2C / corner to corner
Worked on the diagonal in 3-dc blocks. The full deal: graph and row-by-row written instructions.
C2C pattern maker →Single crochet & tapestry
Straight rows, read across the chart and back. You get the graph, the color key and the counts — not written rows.
Filet & mosaic
Two-color grids where filled and open cells carry the design. Draw them the same way, print the same chart.
Pixel crochet
Sprites and pixel art straight onto the grid, at the exact block dimensions you want.
Where the line is, plainly
Charts: every technique above. Written row-by-row instructions: C2C only. The straight-row techniques are worked from the chart itself, and we haven't built the straight-row instruction writer yet. We'd rather say that here than have you find out forty hours into a blanket.
Turn a photo into a graph
Upload a picture, say how many blocks wide you want the blanket, and it's matched block by block against the yarn colors you chose. It's a color conversion, not a generator that invents something plausible — the same deterministic matching the cross stitch and diamond painting sides have used for years.
You land in the editor with an editable graph, not a finished file. Which matters, because photos never convert perfectly the first time: faces need a hand, backgrounds need simplifying, and one stray block of the wrong color is far easier to fix now than to frog later. Reduce the color count, clean up speckle, redraw whatever you like, then print. Starting from a picture? The photo to crochet pattern page covers what to crop, how many colors a graphghan can stand, and what each technique gets from the graph.
Yarn colors and how much you need
Three worsted-weight palettes are built in, the ones blanket makers actually reach for: Red Heart Super Saver, Caron One Pound and Bernat Super Value. Pick one and the color key names every shade you used, with the block count for each.
One honest caveat: the on-screen colors are close matches sampled from official product photos. No yarn company publishes hex codes, and dye lots shift between production runs, so the screen is a guide and a physical skein is the truth. Check one before you commit to a whole blanket.
Not sure how much to buy? The crochet blanket calculator turns a blanket size into blocks per side and yards and skeins per color, with the 2.5 yards per block assumption printed next to the answer.
How it works
1. Set the size
Blocks wide by blocks tall. Crochet a swatch first and measure one block — that's what turns a block count into inches.
2. Draw or convert
Brush, fill, line, shape and text tools, or drop in a photo and edit what comes back.
3. Pick your yarn
Choose a palette and the key totals blocks per color, with a yardage estimate to shop from.
4. Print it
A PDF with the graph tiled across pages, the color key and readable grid lines. For C2C, the written rows too.

FAQ
What kinds of crochet does this make patterns for?
Anything worked from a square grid: C2C (corner to corner), single crochet and tapestry graphghans, filet, mosaic, and pixel crochet. One block on the grid is one block, stitch or square in your work, whichever your technique calls it. Written row-by-row instructions are generated for C2C only — for the straight-row techniques the graph itself is what you work from.
Is this crochet pattern maker free?
Yes. It runs in your browser with no signup and no download. Draw, convert photos, edit, and export for free. Paid tiers unlock watermark-free PDF exports.
Can I turn a photo into a crochet graph?
Yes. Upload a photo, choose how many blocks wide you want it, and it's matched block by block to your yarn palette. It's a deterministic color conversion, not an AI that invents a pattern — you land in the editor with an editable graph and can fix every block before anything prints. Use images you own or have the right to use.
Does it write out the rows for me?
For C2C, yes — every row in working order with direction, RS/WS, color runs and block counts. For single crochet, tapestry, filet and mosaic graphghans it does not: those are worked in straight rows and the straight-row instruction writer isn't built yet. You get the graph, the color key and the counts for those.
How big will my blanket be?
That depends on your hook, yarn and tension, so crochet a small swatch and measure one block. A worsted C2C block on a 5 mm (H-8) hook runs roughly an inch, which makes a 60 × 60 graph about 60 inches square — but treat that as a starting estimate, not a promise, and check your own gauge.
Which yarn colors are built in?
Three worsted-weight palettes: Red Heart Super Saver (72 colors), Caron One Pound (46), and Bernat Super Value (60). The colors are close matches sampled from official product photos, not official values — no yarn company publishes hex codes, and dye lots vary between runs. Check a physical skein before buying for a whole blanket.
Can I print the chart?
Yes. Export a PDF with the graph tiled across pages, a color key with per-color block counts, and grid lines you can actually follow. Page size, cells per page and grid style are all adjustable before you print.
Do I need to know how to crochet already?
To make the chart, no — it's drawing on a grid. To work it, you need the technique itself, which is what the guides are for: how to read a graph, where C2C increases and decreases turn, and how the techniques compare so you can pick one.
