Free Crochet Graph Maker for Photos and Blank Grids
Your image pixels stay local in your browser. Turn a clear photo into an editable stitch grid or begin with a blank canvas. Set independent stitch and row gauge, simplify the palette, check the finished proportions, repair individual cells, and export a printable pattern.
Your image moves directly into the local Studio. It is not uploaded.
A dependable graph-making tool does more than place square cells over an image. It connects grid dimensions, independent stitch and row gauge, editable cells, and written instructions so you can see the effect of each decision before committing it.
This is not a generic crochet pattern generator for garments, shaped pieces, amigurumi, or decorative symbol charts. It is built specifically for flat, turned-row Single Crochet and Tapestry Crochet colorwork, where one graph cell represents one stitch and every row must add up to the selected width.
Frame the subject before reducing detailUpload a JPG, PNG, or WebP file and crop around the subject. The crochet graph maker processes pixels in your browser and previews brightness, contrast, grid size, and color-count changes. A close crop usually produces cleaner shapes than asking a small stitch grid to describe an entire photograph.
Set the grid around the fabricUse the crochet graph maker to begin with a blank chart or convert the cropped image into editable cells. Stitch gauge controls width while row gauge controls height, so the physical preview may look taller or wider than the square editing view. That difference is intentional: it warns you about distortion before yarn and time are committed.
Repair, orient, and exportPaint individual stitches, merge colors, fill connected areas, and confirm where Row 1 begins. The crochet graph maker derives palette totals and alternating written color runs from the same canonical grid. Export a clean PNG, printable PDF, or project JSON only after the graph passes its consistency checks.
Edit individual stitches, compare physical proportions, and verify Row 1 before export.
Make the source easier to stitch
How to turn a photo into a readable crochet graph
Start with an image that has one clear subject, visible edges, and enough contrast between the important shapes. A tightly framed flower, pet silhouette, letter, icon, or geometric motif usually converts more clearly than a busy room or landscape. Crop away empty background before increasing the number of stitches. More cells can preserve detail, but they also create a larger finished piece and more color changes to manage while crocheting.
Choose a grid width that suits both the image and the project you intend to make. A small coaster needs a simpler silhouette than a wall hanging or cushion panel. If an important feature disappears, try a closer crop, a slightly wider grid, or fewer competing background colors before correcting individual cells. Increasing the color count alone rarely restores a shape that does not have enough stitches to describe it.
Compare the square editing chart with the physical preview after every major size or gauge change. Crochet stitches are not always square, so a motif that looks balanced on graph paper may appear wider or taller in fabric. Measurements from a real swatch show the likely proportions without changing which palette color belongs to each cell.
Two honest starting points
Choose a photo or draw the motif yourself
This crochet graph maker supports both image-led conversion and deliberate drawing. Use a photo when the source already has a clear silhouette and limited visual noise. Start blank when you know the motif, dimensions, or repeating geometry you want. Both paths arrive at the same editable grid, gauge preview, palette counts, row orientation, and export checks.
Neither route locks you into the first result. You can move backward to revise size, gauge, crop, or colors. Preview changes remain provisional until you apply them, while saved projects stay recoverable in local browser storage without requiring an account.
Convert a clear photo
The crochet graph maker works best with one recognizable subject, strong edges, and enough contrast between important regions. Direct cropping removes background detail before color reduction. Unlike an opaque crochet pattern generator, the crochet graph maker keeps the generated cells editable and shows a physically proportioned preview beside the square graph.
Build from a blank grid
The crochet grid maker lets you choose stitches, rows, gauge, and an initial background before painting. It serves as a focused crochet pattern maker for original flat colorwork without claiming to design shaping, joins, construction steps, foundation chains, or exact yarn quantities that the grid cannot prove.
One grid, two honest views
Square to edit. Proportioned to plan.
Square cells make painting predictable. Your finished fabric may not use square stitches, so the physical preview derives width from stitch gauge and height from row gauge independently.

Before yarn meets hook
Check size, colors, and Row 1 before exporting
Review the chart at normal size and at a reduced zoom. The reduced view reveals whether the main silhouette is still recognizable, while the close view makes isolated cells and noisy color changes easier to find. Merge shades that are too similar to distinguish in yarn, then confirm that every remaining palette entry has a useful name, code, or symbol. Palette totals should always equal the total number of cells in the graph.
Check the finished width and height against the object you plan to crochet. Stitch gauge controls horizontal size, while row gauge controls vertical size, so changing one measurement must not silently alter the other. If the physical preview looks distorted, revisit the grid dimensions or swatch measurements instead of stretching the artwork by eye.
Finally, confirm where Row 1 begins and which direction it is worked. Turned-row colorwork alternates direction, so an unclear starting edge can reverse the written instructions even when the grid itself looks correct. The PDF should agree with the on-screen chart, palette counts, row runs, gauge assumptions, and finished dimensions. Save project JSON as well because it preserves the editable cells and settings needed for later revisions.

Supported honestly
Flat, turned-row colorwork
One cell represents one Single/Tapestry Crochet colorwork stitch. The crochet graph maker does not generate true C2C diagonals, shaped garments, amigurumi construction, exact yarn quantities or in-the-round tapestry instructions.
Before you begin
CrochetGraphLab answers the graph questions
What does this crochet graph maker create?
It creates flat, turned-row Single/Tapestry Crochet colorwork graphs and written color runs, not shaped construction.
Why does the physical preview look stretched?
Stitch gauge controls width and row gauge controls height. The preview shows that measured fabric ratio without changing cells.
Where is my uploaded photo stored?
It is decoded in your browser and remains available only in the current tab. Saved projects keep graph settings and cells, not the source file, a preview asset or its filename.
