Two-color symbol: Pixel-to-Crochet Chart Converter

A directional arrow that reveals mirroring

The thirteen-square source draws a dark right-pointing arrow on white. Its horizontal shaft joins a wider triangular head ending in one tip cell. This original geometry is useful when learning the difference between image coordinates and alternating crochet row order. A reflected arrow is clearly wrong even if its pixel total remains unchanged.

Verify the head and shaft together

The arrow occupies thirty-seven dark pixels and leaves 132 white pixels, totaling 169. Its shaft is three rows high through the central area. The head overlaps the shaft, so the total cannot be found by adding two complete shapes without accounting for their shared cells. Compare the exact native bitmap and locate the single right-hand tip before conversion.

Keep the upload at native resolution first

Use thirteen columns, thirteen rows and two maximum colors. This first trial preserves every source pixel without resampling. A wider or taller conversion asks the browser to scale the picture, potentially creating intermediate shades along an edge before quantization. That can change the final whole-cell outline. Treat a resized result as another design and compare its head width and tip, rather than expecting the original thirty-seven-cell budget to survive every resolution.

Follow the actual working route

The first crochet row begins at the bottom right of the displayed rectangle and later rows alternate direction. That does not mean the arrow should change direction on alternate rows. The generated written sequence already reverses the order in which cells are worked. Keep the source drawing fixed, and compare a marked arrow tip with the complete front-view graph before weaving in the ends.

FAQ and likely mistakes

Can I use the arrow as a freestanding motif?

This saved construction includes all white background cells. A shaped applique needs a separately designed boundary and row structure.

Why did the arrow become blunt?

Check whether the source was resized and whether its single tip cell survived quantization. Restore the native project for comparison.

Does two colors mean each uses half the yarn?

No. The visible regions have unequal cell budgets, and carried strands and tails further affect consumption. Measure the actual intended construction.

Download the source and reproduce the conversion

Download the original PNG input. This code-drawn illustration is shown enlarged with crisp pixels below; it is not documentary photography.

In the Pixel-to-Crochet Chart Converter, set 13 columns, 13 rows and a maximum of 2 colors before choosing the PNG file. Conversion occurs locally. Use Reprocess source image after changing resolution or the color limit. The exact native source uses 2 output palette slots: yarn 1 #ffffff (132 stitches); yarn 2 #202e45 (37 stitches).

Download the exact converted project JSON for restoration and comparison. The saved grid uses the lower-left origin. Preserve it before trying another image or palette; a resized or reduced version is a separate design.

Work the actual counted fabric

Use compatible smooth yarns and a suitable trial hook. Chain 14 and work 13 US single crochets from the second chain. Later rows use one uncounted turning chain and alternate working direction. Change color on the final pull-through before the next yarn. In UK terminology these single crochets are double crochets. Follow every row below, then fasten off and weave ends. Measure a washed sample for physical dimensions and material consumption; the pixel budget excludes carries, tails, seams and any later border. See the chart-reading guide for matching the symbols to the written route.
