Free LEGO Mosaic Maker
Photo to LEGO Art · 40 Brick Colors · BrickLink Export

A LEGO mosaic maker converts a photo into a pixel grid where each cell equals one 1×1 LEGO brick. The tool maps your image to the closest in-production LEGO brick colors and outputs a mosaic plan plus a brick count list. BeadPattern's tool also generates a BrickLink Wanted List XML so you can source every brick without manual counting.

Yes. You can upload a photo and generate a full LEGO mosaic brick plan for free. No account required to get started. Premium features like high-resolution export and AI pattern generation are available on paid plans.

You can create portraits, pet photos, logos, landscape pixel art, or any image-based design. Flat mosaics built from 1×1 plates or tiles on a baseplate are the most common type. More advanced builders create framed hanging mosaics or multi-baseplate murals — all of which you can plan with this tool by adjusting the grid size.

A 48×48 mosaic has 2,304 studs. At a relaxed pace of roughly 150–200 bricks per hour, expect 12–15 hours of building time. Sorting bricks by color beforehand dramatically speeds up assembly. Many builders finish a single-baseplate mosaic in a weekend.

The best photos have a clear subject, good contrast, and a relatively simple background. Portraits with a plain backdrop, bold logos, and high-contrast landscapes convert exceptionally well. Very detailed images with many similar colors may lose fine details because the LEGO palette has only ~40 colors — simplifying or cropping tightly before uploading gives better results.

The most common choice is the 1×1 Plate (Part #3024), which is widely available on BrickLink in all standard colors and gives a clean, flat surface. Alternatives include the 1×1 Tile (Part #3070b) for a completely smooth surface, and the 1×1 Round Plate (Part #4073) for a circular-stud look. This tool's BrickLink XML supports all three part types.

The LEGO standard baseplates come in 32×32 and 48×48 stud sizes. A 48×48 grid gives good detail for portrait mosaics and fits onto one standard large baseplate. For bigger projects, tile multiple baseplates together — adjust the grid size in this tool to match (e.g., 96×96 for a 2×2 baseplate arrangement).

LEGO mosaics use rigid plastic interlocking bricks (~8mm per stud) while Perler bead art uses small iron-meltable beads (~5mm). LEGO mosaics are more durable, can be disassembled and rebuilt, and the pieces are widely resalable on BrickLink. Perler art is typically cheaper to source but is fused permanently once ironed. Both use a similar pixel-grid approach for design.

You can upload JPG, PNG, GIF, and WebP images up to 10 MB. For best mosaic quality, upload a square or portrait-oriented photo. The tool automatically resizes the image to fit the selected grid (default 48×48). Higher resolution source images are recommended to capture more detail during the color-mapping step.

The tool includes ~40 in-production LEGO brick colors — covering all standard LEGO hues from the current BrickLink Color Guide. You can use the color merge slider to reduce the number of distinct colors in your design (fewer colors = cheaper and simpler to source). Most builders aim for 8–15 colors for an affordable mosaic.

Yes. After generation you can use the built-in color picker to repaint individual cells, adjust the number of colors using the merge slider, and change the grid size. This lets you simplify difficult areas (like faces) and reduce brick variety before downloading the final plan.

A 32×32 single baseplate mosaic (1,024 bricks) is ideal for beginners. It is fast to build (4–6 hours), affordable (around 1,000–2,000 bricks total), and gives a clear result. Once comfortable, 48×48 is the most popular size, offering better detail with a manageable brick count.

After generating your mosaic, click the download button and choose 'Export Brick List'. The tool outputs a complete brick count table sorted by LEGO color — showing the color name, BrickLink Color ID, and quantity needed. This list is also embedded in the BrickLink Wanted List XML export.

Yes — that is one of the main features. Click 'Export BrickLink XML' to download a Wanted List file. Log in to BrickLink, go to My Wanted List → Upload, and import the file. BrickLink will automatically find sellers for all the brick colors and quantities your mosaic requires.

A 48×48 mosaic requires 2,304 bricks (1×1). A 32×32 mosaic needs 1,024 bricks. Actual numbers per color depend on your image. The brick list shows exact quantities per color. On BrickLink, 1×1 plates typically cost USD 0.02–0.08 each depending on color and seller, so a 48×48 mosaic usually costs USD 50–150 in parts.

Once you have your brick list, the easiest method is to import the BrickLink XML Wanted List and use BrickLink's 'Easy Buy' feature to see the total cost across all sellers. On average, 1×1 white and gray bricks are cheapest; specialty colors like Coral or Copper cost more. Budget USD 50–200 for a 48×48 mosaic depending on colors used.

Yes. After generating your mosaic, use the 'Export PNG' option to download a printable grid. The exported chart includes color-coded cells and a color legend. Print it at A4 or Letter size for a comfortable building reference. The chart also shows each color's name and BrickLink Color ID for easy cross-referencing while sorting bricks.

1) Log in to your BrickLink account (free to create). 2) Go to My Wanted List. 3) Click 'Upload Wanted List' and select the XML file exported from this tool. 4) BrickLink parses the list and shows you all the lots matching your needed bricks. 5) Use 'Easy Buy' to automatically select the cheapest combination of sellers that fulfills your entire list.

Popular display options include: mounting the baseplate directly on a wall with LEGO plate hangers, framing the mosaic inside a shadow box frame, or using official LEGO frame systems. For larger multi-baseplate mosaics, securing the baseplates together with a thin backing board before framing keeps everything flat. Adding a glass front protects the bricks from dust.

Yes. This tool includes an AI pattern generation mode — describe your desired image and the AI creates a pixel art pattern mapped to LEGO brick colors. You can then download the brick list and BrickLink XML just as you would for a photo-based mosaic. AI patterns are especially useful for abstract designs, geometric art, or when you want full control over the color palette.

All three parts are 1×1 in size and fit standard LEGO baseplates. The 1×1 Plate (Part #3024) has a stud on top — most common and inexpensive. The 1×1 Tile (Part #3070b) is flat with no stud — gives a smooth, tile-like surface preferred for framed mosaics. The 1×1 Round Plate (Part #4073) has a circular footprint — creates a cool dot-matrix look. This tool's BrickLink XML export supports all three; choose your preferred part type before exporting.
