Pixel Art Grid Maker

A pixel grid describes an image as rows and columns of colored cells. The converter samples the source image, assigns a color to each cell, and displays the result as a block-based version that can be edited. Each square is a position in the design; it is not automatically a physical bead, stitch, brick, or Minecraft block unless you use a tool built for that material.

The grid is useful because it makes detail measurable. Instead of asking only whether an image looks pixelated, you can decide how many cells define its silhouette, how many colors are available, and whether each cell should remain a clean solid block.

• Grid width controls the number of columns; the image height follows the source proportions.
• Color count limits the palette used to approximate the source.
• Cell edits let you correct the generated result without redrawing the whole image.

A good source has one main subject, enough contrast to distinguish its outline, and a background that does not compete with it. A close crop of an object often gives the converter more useful pixels to work with than a wide scene where the subject occupies only a small part of the frame. Simple illustrations and logos can also work when their outlines and color regions are distinct.

A detailed photograph may still be a useful starting point, but small textures and subtle color changes will be grouped or removed as the grid gets smaller. If the result loses the feature that makes the subject recognizable, try a larger grid, simplify the source before loading it, or use cell edits to restore the essential shape.

Grid width is the number of cells from the left edge to the right edge. Fewer columns mean each cell covers more of the source and creates larger visible blocks. More columns preserve narrow edges and small features, but they also create a busier grid that may be harder to follow when printed or recreated by hand.

The height is calculated from the source image proportions. A square source remains close to square, while a wide or tall source keeps its shape. For a design intended for a physical project, decide the desired width first and review the resulting height before you count materials or choose a print size.

A maximum color count sets how many different colors the converter may use. Fewer colors can make the result easier to read and reproduce, while more colors can preserve additional shading. The best setting depends on the subject and destination: a simple icon may need only a few clear tones, while a shaded object may rely on more colors to keep its volume.

Dithering places neighboring palette colors in a pattern to approximate a color between them. It can make a gradient feel less abrupt, but it adds texture and more visual variation to neighboring cells. Compare the preview with dithering off and with the available algorithms; keep the version whose shapes are easiest to recognize at the size where you will use it.

Generated grids are a starting point. A single misplaced cell can interrupt an outline, merge two shapes, or make a small feature disappear. Paint a cell when you need a precise color correction; use Fill for a connected area; pick a color from the existing grid when you want consistency; and erase a cell when the pattern should have an empty position.

Review the design at both its working size and the size at which it will be viewed. A zoomed-in grid makes it easier to place cells, while a full-image preview reveals whether the overall silhouette still reads. Undo and redo are available while you work, but save useful exports before leaving the page because projects are not stored for a later session.

A clean PNG is suited to sharing or placing the pixel artwork in another design because it omits the chart markings. The pattern PNG can include visible grid lines and optional cell labels, which help when you need to locate a specific row and column. If transparency is enabled, inspect the exported edges against the background where the artwork will appear.

A printable PDF includes a grid and color key for following the design away from the editor. Print scale and paper layout affect how large the cells appear on paper; large grids may span multiple pages. Treat the PDF as a reference and check that the labels and key are readable before beginning a long craft or build.

The image is processed locally in the browser rather than sent to the converter. This describes how the current tool handles conversion; it does not mean the page saves your project automatically. The editor does not provide an account-backed library or a way to reopen an unfinished grid after the session ends.

Download the version you want to keep before refreshing or closing the tab. If the source is private or sensitive, you can also check your browser extensions and device environment, which are outside the editor’s control. For very large images, resizing a copy before loading it can make the editing process easier on the device.
