About this tool
Turn a photo into a buildable LEGO mosaic. Every colour in your image is matched to the nearest real LEGO brick colour from the current production range, so the parts list this produces is something you can actually order and build.
How to use this tool
- Upload reference photoChoose an image with clear lighting and subject separation.
- Set mosaic sizePick stud width/height based on available baseplates and desired detail.
- Tune palette and ditheringAdjust color mapping for smoother shading or cleaner flat regions.
- Export plan and parts listDownload build grid plus required LEGO color counts for shopping.
Key features
- Produces real-world buildable mosaic plans, not abstract art only.
- Maps colors to actual available LEGO palette constraints.
- Includes practical brick count output for project planning.
- Useful for hobbyists, classrooms, and maker events.
Common uses
- Creating custom LEGO portraits and wall mosaics.
- Planning school STEM or maker-lab build activities.
- Generating gift projects from family or pet photos.
- Producing fan-art build guides for communities.
Tips for better results
- Start with medium size first to estimate parts budget realistically.
- Use dithering for portraits, disable for logo-style artwork.
- Prefer high-contrast source images for clearer brick patterns.
- Print or zoom the grid while building to avoid row mistakes.
Mistakes to avoid
- Choosing very large mosaic size without checking part cost.
- Using cluttered background photos that create noisy brick maps.
- Skipping color legend and buying incomplete thread/brick sets.
- Expecting photo-realism from a limited physical color palette.
Frequently asked questions
Yes. The palette uses official LEGO colour names and IDs from bricks currently in production, so every colour in the parts list can be bought. Retired colours are deliberately excluded - matching to a brick you cannot obtain would make the plan useless.
LEGO has a limited palette, so smooth gradients would otherwise turn into flat bands of colour. Dithering scatters the rounding error into neighbouring studs, which the eye blends back into shading. It makes skin tones and skies look far more natural, at the cost of a slightly busier pattern.
A 48-stud width is a good balance and fits a standard baseplate. Larger sizes capture more detail but the part count grows quickly - doubling the width roughly quadruples the number of bricks needed.
Download the PNG for the visual plan and use 'Copy list' for the part counts. Build row by row from the top of the image. 1x1 plates on a baseplate are the usual approach for mosaics.
Yes. Lego Art is free for normal use with no account required, and ToolBox does not add a watermark to your result.
