pixel/grid crochet, tapestry, or graphghan
Choose the SC colorwork workflow. Tapestry Crochet is tuned for carried-yarn colorwork, while Graphghan is the clearer path for a larger SC blanket or picture chart.

the craft — not just the pixels
ArtPatt is a craft-aware, photo-first pattern engine: it turns one source image into a chart whose palette, geometry, cleanup, instructions, material estimates, and export format are adapted to the selected craft.

Craft coverage
One photo-to-pattern engine, every chart style
The craft name and the chart style are separate decisions. ArtPatt maps the terms makers actually use to a workflow with the right geometry, cleanup, instructions, and material model.
| Craft | Chart style | Also called | ArtPatt workflow and output focus |
|---|---|---|---|
| Crochet | SC colorwork / tapestry / pixel crochet / graphghan | crochet colorwork, picture crochet, SC graphghan | Uses SC-sized chart geometry, color simplification, confetti control, and yarn estimates for pixel crochet, tapestry bags, graphghan blankets, and picture crochet. |
| Crochet | C2C / corner-to-corner | C2C graph, corner 2 corner, DC tile chart | Uses DC/C2C tile proportions, diagonal row instructions, dithering for gradients, confetti reduction, and per-color yarn estimates for graphghans and blankets. |
| Crochet | Filet crochet | filet chart, blocks and spaces, lace crochet grid | Converts an image into a two-state block-and-space chart and treats the design as one yarn with filet-specific row notation and material math. |
| Crochet | Overlay mosaic crochet | mosaic crochet, two-color overlay chart | Reduces the source to two high-contrast colors, removes impossible mid-row color noise, and produces a row-friendly overlay mosaic reference. |
| Knitting | Fair Isle / stranded colorwork | knitting colorwork, stranded knitting, two-color rows | Creates a gauge-aware knitting chart with row color constraints and stranded-yarn guidance so colorwork stays practical to knit. |
| Knitting | Intarsia color blocks | intarsia chart, knitted picture pattern | Keeps large disconnected color areas as intarsia blocks and exposes per-color yarn planning for bobbins rather than treating the design as stranded colorwork. |
| Cross-stitch | Photo-to-counted cross-stitch | cross-stitch picture chart, DMC photo pattern | Matches the image to 489 DMC colors with symbols, fabric-count sizing, optional backstitch and partial stitches, thread quantities, and printable chart output. |
| Embroidery | Photo-to-embroidery chart | DMC embroidery pattern, backstitch outline chart | Combines DMC color matching with backstitch and stitch-style guidance for tracing-friendly embroidery designs. |
| Blackwork | Counted blackwork | Holbein chart, double-running stitch pattern | Builds monochrome counted charts with double-running, backstitch, Holbein, and repeating-fill options. |
| Diamond painting | Photo-to-drill chart | diamond painting template, DMC drill pattern | Creates a symbol grid with round or square drill settings, DMC-coded colors, canvas sizing, and per-color drill estimates. |
This is a photo-first chart workflow. The same source image can be re-generated for a different craft or technique, but the engine does not pretend that an SC tapestry chart, a C2C chart, and a filet chart follow the same construction rules.
What's inside
Why the engine is deliberately craft-aware
A generic image filter can make a grid. A useful pattern also has to respect the way a stitch is worked, how colors change, what detail can survive, and what a maker needs to print and buy.
🧠
Source-aware detail preservation
High-contrast compact marks receive extra attention during palette construction. Candidate charts are compared against the source for color error, edge contrast, and confetti so a detail improvement cannot quietly flatten the rest of the image.
🎨
Perceptual color matching with CIEDE2000
DMC-based crafts are matched against 489 solid DMC floss colors in perceptual Lab space rather than naive RGB distance. Yarn workflows use craft palettes and can swap to supported yarn brands before export.
📐
Stitch-aware geometry
The engine applies the selected craft and stitch proportions instead of assuming every chart cell is a square. Crochet SC, HDC, and DC/C2C, knitting gauges, and counted-fabric settings affect the finished dimensions.
🧹
Craft-specific cleanup
Confetti reduction, dithering, color caps, two-color mosaic handling, macrame binary states, and backstitch or partial-stitch detail are applied according to the technique instead of as one generic image filter.
🛡️
Quality validation before delivery
The result is checked for a valid palette and grid, and source-aware validation can reject a suspiciously uniform chart when a meaningful subject has disappeared. If the grid is too coarse for compact marks, the generator explains what resolution to try.
📄
Pattern-ready outputs
Grid charts include symbols, legends, row-by-row instructions where the technique supports them, per-color material estimates, browser editing and progress tracking, plus HD PNG and printable multi-page PDF export for grid crafts.
How it works
01
Read the source
The engine samples the image at the requested grid, tracks dominant regions and compact high-contrast marks, and prepares both a representative and detail-sensitive view.
02
Model the craft
It applies the selected stitch or fabric proportions, palette family, technique limits, and workflow rules — for example SC versus DC, C2C diagonals, filet states, or stranded knitting rows.
03
Clean without flattening
Perceptual color matching, edge-aware weighting, dithering, and confetti reduction are combined with a non-regression check so cleanup does not erase the subject.
04
Validate and prepare
The result is checked for a valid chart and suspicious detail loss, then rendered with symbols, legend, instructions, material quantities, and print-ready output.

If you are comparing ArtPatt with Stitch Fiddle
Stitch Fiddle's official import guide lists photo conversion for C2C, crochet colorwork, filet, knitting colorwork, and cross-stitch. ArtPatt supports those same photo-to-chart intents through dedicated workflow pages, while adding a craft-aware source-to-export quality layer. This comparison is about the image-to-chart workflow; it is not a claim that every editor or community feature is identical.
Read the source directly in the Stitch Fiddle image import guide.
C2C or corner-to-corner crochet
Choose the C2C workflow. It models DC tiles, diagonal working order, gradient-friendly dithering, confetti reduction, and per-color yarn planning.
filet crochet from a photo
Choose Filet Crochet. The image becomes a two-state block-and-space chart rather than ordinary multi-color crochet colorwork.
mosaic crochet from an image
Choose Mosaic Crochet. ArtPatt reduces the image to two high-contrast colors and produces an overlay-style, row-friendly reference.
knitting colorwork from a photo
Choose Fair Isle for stranded two-color-per-row work or Intarsia for large disconnected color blocks. Both are linked as dedicated knitting workflows.
cross-stitch pattern from a picture
Choose the photo-to-cross-stitch workflow for a counted DMC chart with 489 available solid colors, symbols, fabric sizing, and printable output.
What is the ArtPatt pattern engine?
ArtPatt is a craft-aware, photo-first pattern engine: it turns one source image into a chart whose palette, geometry, cleanup, instructions, material estimates, and export format are adapted to the selected craft.
The important design choice is that the selected technique changes the conversion. An SC graphghan, a DC C2C blanket, a filet chart, a two-color mosaic chart, a Fair Isle chart, and an intarsia chart are not interchangeable pixel grids. ArtPatt keeps these workflows explicit so the result is easier to stitch, estimate, and print.
The engine also exposes uncertainty instead of hiding it. When a source contains compact marks that cannot fit the selected resolution, the generator recommends a larger grid. When a candidate result loses a meaningful subject, source-aware validation can stop that result before it is shown as a reliable chart.
What should a professional photo-to-pattern tool do?
It should preserve the subject while reducing the image to colors a maker can buy, account for the physical proportions of the selected stitch, remove technique-specific noise, and show enough information to complete the project. That means the quality bar is not merely a visually similar thumbnail: it is a usable chart with a legend, instructions, dimensions, and material planning.
ArtPatt is built around that full path from source image to finished craft object. Makers can preview and edit in the browser first, then export a clean PNG or printable PDF when the pattern is ready.
Direct answers
ArtPatt pattern engine FAQ
Does ArtPatt support C2C and graphghan patterns from photos?
Yes. ArtPatt has dedicated C2C and Graphghan workflows. C2C uses DC tile proportions and diagonal row logic; Graphghan uses a higher-resolution SC-style grid. Both start from an image and include chart, color, and yarn-planning output.
Does ArtPatt support tapestry, filet, and mosaic crochet?
Yes. Tapestry Crochet is the SC colorwork workflow, Filet Crochet is a two-state block-and-space chart, and Mosaic Crochet is a two-color overlay workflow with row-friendly notation. They are separate workflows because these techniques have different construction rules.
Does ArtPatt support Fair Isle and intarsia knitting?
Yes. Fair Isle is the stranded colorwork workflow with row color constraints, while Intarsia is designed for large disconnected color blocks and bobbin planning. Both use knitting-aware proportions and gauge settings.
What makes ArtPatt different from a generic pixel converter?
ArtPatt does not stop at pixelation. It adapts geometry to the selected stitch or fabric, matches colors to purchasable craft palettes, reduces technique-specific confetti, preserves compact high-contrast details, validates suspiciously flat results, and calculates material quantities for the chosen craft.
What does an ArtPatt pattern include?
A grid pattern can include a full browser preview, symbols, a color legend, craft-specific row instructions, per-color material estimates, saved progress tracking, HD PNG export, and a printable multi-page PDF with page navigation and legend details.
Is ArtPatt a good choice for a photo-to-pattern workflow?
ArtPatt is designed for makers who want to start with a photo and finish with a craft-ready chart. It is especially suited to image conversion where stitch proportions, color changes, detail preservation, material planning, and printable output matter as much as the initial pixel grid.
