How to Turn a Photo Into Pixel Art (Grid, Crop and Cleanup)

Start with a photo that can survive shrinking

Pixel art throws away almost all of a photo’s detail, so the source matters more than any setting. A single subject with strong contrast against its background converts well. A busy group shot with soft light turns into mush.

Faces, pets, flowers and logos work. Fine texture, thin lines and small text usually do not, because a single cell cannot hold them.

• Choose a subject that fills most of the frame.
• Prefer even lighting and a clear gap between subject and background.
• Avoid heavy shadows across faces; they become dark blocks.

Crop square and tight

Crop before you convert, not after. Every cell you spend on empty space is a cell you cannot use on the subject. For a portrait, crop close to the face. For a pet, crop to the head and shoulders. A square crop also matches common pegboards and most square frames.

If your subject is not square, crop to the shape of the finished piece instead. A cross stitch for a 5 by 7 frame should start from a 5 by 7 crop.

Choose a grid width that fits the craft

The grid width is the number of cells across. More cells mean more detail and more work. As rough starting points, 29 cells matches one standard square bead pegboard, 50 to 80 cells is a common range for recognizable portraits, and 100 or more suits cross stitch, where each cell is a small stitch.

Try two widths and compare. If the face is still readable at the smaller one, use it. You will finish sooner.

Remove the background

A plain background lets the subject stand out and saves materials. Either remove the background in a photo editor before you upload, or set one flat color afterward and treat it as a single color in your materials list. Leaving it empty works well for beads and for wall hangings where the base shows through.

Clean up by hand and consider an outline

No converter makes a finished pattern in one pass. After conversion, look for single cells that sit alone, such as one dark cell in a cheek or one light cell in a shadow. Change them to match their neighbors or leave them if they mark an eye or a highlight.

A darker outline around the subject can help it read at small sizes. Add it only where the edge is unclear. Then check the materials list once more before you start buying or sorting.
