Generator Tool
LEGO Mosaic Generator for Buildable Brick Art
Try a photo in BMBrick's free LEGO-compatible mosaic generator. Use the preview to compare crop, size, palette, and material before spending on a build. The complete personal PDF and route-specific parts files are paid exports; physical bricks are purchased separately.
Direct Answer
BMBrick generates a free photo mosaic preview in the browser. It supports 3024 square plates and 98138 round tiles, with route estimates and paid PDF, PAB, Webrick, BrickLink XML, and structure BOM exports for a confirmed build plan.
Generate Free
Convert a photo into a free mosaic preview and adjust crop, palette, size, and material. Purchase complete personal build files when the plan works.
Generator Strength
Connects visual preview to route data and build instructions instead of treating the render as the entire product.
Best Next Step
Run one real image through the editor and compare the output before reading more theory.
How the workflow works
01 - Start with the image
Upload a photo and use the workspace to choose a crop that still reads from normal viewing distance.
02 - Set size and material
Pick a preset size and choose between square 3024 plates or round 98138 tiles.
03 - Tune palette and route
Review allowed colors, route availability, and estimated parts total before the blueprint is locked.
04 - Download practical outputs
Export PDF grid instructions, vendor-specific files, and the final image when the build plan is ready.
Generator output matrix
The generator should answer both visual and practical questions.
| Output | Format | Use | Why it matters |
|---|---|---|---|
| Mosaic preview | Browser canvas and HD image | Judge visual quality | Shows whether the crop and palette work |
| Build instructions | PDF with symbol legend and grid pages | Assemble the mosaic | Reduces color confusion during long builds |
| PAB export | CSV and JSON | Official-route planning | Keeps element IDs and quantities structured |
| BrickLink export | XML | Marketplace inventory upload | Speeds up seller route planning |
| Webrick export | CSV and notes | Compatible-part sourcing | Supports broader route comparison |
What to compare when choosing a generator
The right generator is the one that lowers project risk. A glossy preview is not enough if the palette is unrealistic, the parts route is unclear, or the instructions are too tiring to follow.
For BMBrick, the strongest differentiator is the connection between the workspace and exports. The same project state drives the preview, route estimate, PDF, CSV, XML, and BOM outputs.
- Check whether the tool exposes part style, not only image size.
- Check whether the export files match the selected route.
- Check whether the PDF is designed for building, not only documentation.
Inspect an output before buying a blueprint
Download the public sample to check the PDF's overview, legend, grid pages, and matching parts files. A buildable plan should let you trace the same grid, material, and quantities across the preview, instructions, and buying inventory.
For your own photo, generate and adjust the preview free before purchasing the complete exports. Check every required color against the supplier's current cart. Webrick exports can include manual-order notes when a color cannot be uploaded safely; BrickLink purchasing depends on seller stock and shipping.
How route estimates should be read
Catalog scope: BMBrick's data was verified April 6, 2026 and generated April 15, 2026. Prices are USD planning estimates from that snapshot, not live supplier quotes or stock guarantees. Physical bricks, base/support hardware, display hardware, tax, and shipping are separate from the paid digital blueprint.
