Image to CSS Grid Layout - Online Pixel‑Based Generator

This tool converts any raster image into a pixel art representation built entirely with CSS Grid Layout. Each pixel becomes a <div> grid cell with an inline background color — no canvas, no JavaScript rendering on the output side. The result is a pure HTML+CSS artifact you can embed anywhere.

Adjust the Columns slider. Fewer columns produce larger, chunkier pixels (more pixelated). More columns preserve finer detail but increase the number of grid cells. Common values range from 16 (heavy pixelation) to 64 (detailed). The row count is automatically calculated from your image's aspect ratio.

PNG, JPG, GIF, WebP, and SVG are all supported. PNG is recommended if your image contains transparency — the tool preserves alpha channels and renders them as transparent cells over a checkerboard background in the preview.

This is likely a CORS (Cross-Origin Resource Sharing) issue. Browsers block canvas pixel reading from cross-origin images for security. Use same-origin URLs, or ensure the remote server sends the Access-Control-Allow-Origin header. Alternatively, download the image and upload it directly via drag-and-drop — that always works.

When enabled, the image is resampled using nearest-neighbor interpolation — this preserves hard edges and creates the crisp, blocky look of classic pixel art. When disabled, bilinear smoothing is applied, producing softer transitions between pixel blocks. Toggle it to see which style you prefer.

Yes. The output is standard HTML with inline CSS — no dependencies, no JavaScript. It works in all modern browsers. For very large grids (100+ columns), consider the DOM weight: a 64×64 grid creates 4,096 elements. For production use cases requiring thousands of pixels, a box-shadow or SVG-based approach may be more performant.

Fully transparent pixels are output as background-color: transparent. Semi-transparent pixels use rgba() notation. The preview shows a checkerboard pattern behind transparent areas so you can see exactly what will render. To replace transparency with a solid color, edit the image before uploading.

For icons and small decorative elements, 4–8px per cell works well. For hero images or larger displays, 10–20px creates a bold pixel art statement. The total grid width = columns × pixelSize + (columns−1) × gap. Keep this under ~800px for comfortable viewing on most screens.

The generated code uses inline background-color on each grid cell. You can manually tweak any cell's color by editing its style attribute in the HTML. For more complex editing, consider using a dedicated pixel art editor and then re-importing the image here.

The tool handles images up to 10MB. The maximum grid is 128 columns (≈16,000+ cells for square images). Beyond that, DOM rendering may become sluggish. For reference, a 64×64 grid (4,096 cells) renders smoothly on all modern devices. The tool warns if the total cell count exceeds 12,000.
