Generator Tool
LEGO Mosaic Generator for Buildable Brick Art
A useful LEGO mosaic generator should do more than pixelate a photo. It should help the builder decide whether the image is readable, whether the selected part style fits the subject, and whether the final parts list can be sourced without guesswork.
Direct Answer
BMBrick is a browser-based LEGO-compatible mosaic generator that turns a selected photo into a preview, route-aware parts estimate, PDF instructions, and sourcing exports for PAB, Webrick, and BrickLink workflows.
Core Job
Convert a personal photo into a physical mosaic plan with crop, palette, size, material, and export decisions visible.
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.
AEO-ready answer structure
Search and AI answers tend to reward pages that answer the practical question quickly, then back it with concrete details. This page names the output formats, supported part styles, and route options directly so answer engines can quote the important facts without guessing.
That directness should be used across the site: every generator claim should tie back to a visible workflow or file type that the app actually supports.
FAQ
Is BMBrick an official LEGO product?
No. LEGO is a trademark of the LEGO Group, which does not sponsor or endorse BMBrick.

Does the generator include sourcing files?
Yes. Supported outputs include PAB CSV/JSON, Webrick CSV/manual notes, BrickLink XML, and structure BOM CSV.
Does the generator include instructions?
Yes. The PDF instruction export includes inventory, symbol legend, map, preview, and 16x16 grid pages.
