From photo to chart

Upload a photo, get a chart you can edit

Your photo comes back as a grid chart with its stitch count, color key and yarn weight, and every stitch is yours to change before you export.

The problem

The chart is the slow part

You already know the blanket you want: your dog's face, your grandmother's photograph, the view from the cabin. Getting there means squaring the photo onto graph paper by hand and counting rows for an evening or three, or opening a charting tool that was never built to take a photograph at all. Either way the hook sits on the table while you do arithmetic, and what comes out is often something you cannot change once you see it in yarn.

A grid chart with its own color key

Your photo comes back as a grid chart with its stitch count, its color palette and its yarn weight noted beside it, ready to read row by row.

Change stitch count, colors, single stitches

The editor holds the whole chart. Raise the stitch count for more detail, swap the palette, set a different yarn weight, or fix one stitch on its own.

How it works

From sign-up to the first result

  1. Pick the photo

    Choose a photo on your phone and confirm it is yours to use. Good light and one clear subject keep the detail that survives being squared onto a grid.

  2. The subject comes forward

    Background clutter is set aside so your dog, or your grandmother's face, sits on a plain ground instead of competing with a sofa and a lamp.

  3. Read the chart

    The grid arrives with its stitch count, color key and yarn weight, each color shown as a small swatch beside its name and row number.

  4. Change what you want

    Set a higher stitch count if the eyes need more room, swap the colors for yarn already in your stash, and edit single stitches by hand.

  5. Export and start hooking

    Save a PDF to print for craft night, or download the chart file and upload it to your own Ravelry library.

Who it is for

Built for the people who feel the problem

For who it covers, see the pages this site publishes.

Pet portraits

A blanket of your own dog

One phone photo of a golden retriever becomes a grid you can set to throw size, with the color key and yarn weight sitting next to it.

Family tapestry

A family photograph, stitched to hang

Chart a photo of the people in it, then raise the stitch count until the faces read from across the room rather than from arm's length.

Gift makers

A charted gift from their own photo

Work from a photo the recipient sent you, and have the chart printed before the yarn order arrives.

Stash crocheters

Charts matched to the yarn you own

Swap the chart's palette for the colors already in your bins, and set the yarn weight you are actually working with before you count a single row.
