How do I turn a photo into a crochet pattern?

Upload any photo (JPG, PNG, or WebP) to the AeternaCraft Studio. The AI quantises the image to between 2 and 32 colours drawn from a real yarn palette, maps each pixel to a single crochet stitch, and generates a pixel-perfect grid with row-by-row written instructions and a corner-to-corner (C2C) tutorial. Your first pattern is free; no signup is required for the first generation.

What image formats and sizes can I upload?

The Studio accepts JPG, PNG, and WebP files up to 10 MB. Square or near-square images work best because crochet grids are typically rectangular. The tool automatically resizes your image to the grid width you choose (20 to 200 stitches), preserving the aspect ratio.

How many colours can I use in one crochet pattern?

You can choose any number of colours between 2 and 32. Fewer colours (4 to 8) produce a bold, graphic look and are easier to follow for beginners. More colours (16 to 32) capture photo-realistic detail but require more yarn colours and more frequent colour changes. The AI selects the optimal palette from a real yarn library so every colour is something you can actually buy.

What is the difference between single crochet (sc) and corner-to-corner (C2C)?

Single crochet (sc) pixel grid is the default mode: each pixel becomes one single crochet stitch, worked in rows from bottom to top. Corner-to-corner (C2C) mode maps each pixel to a small diagonal block (typically 3 chains + 3 dc), worked diagonally from one corner to the opposite. C2C is faster for large pieces and produces a distinctive diagonal texture; sc produces a tighter, more pixel-accurate grid.

What file formats can I export my crochet pattern to?

Every pattern exports to three formats: PDF (printable pattern with colour grid, legend, and row-by-row instructions), PNG (the colour grid image for screen use or social sharing), and CSV (stitch counts per colour, for advanced makers who want to plan yarn math). The PDF also includes a recommended yarn kit with brand, weight, and approximate yardage.

Is AeternaCraft Studio free to use?

Your first pattern is completely free — no signup required. After that, you can pay per pattern or subscribe for unlimited generations. The free first pattern includes all export formats (PDF, PNG, CSV) and the recommended yarn kit. Subsequent patterns require an account so we can save your project history and yarn kit recommendations.
