Frequently Asked Questions
Is the Brickapic LEGO mosaic generator free to use?
Yes, Brickapic is 100% free with zero catch. There are no paywalls, hidden feature micro-transactions, or account registrations required to convert pictures into custom LEGO mosaic blueprints or download your printable manuals.
Is my uploaded picture secure and private?
Absolutely. Your privacy is protected because all image processing, pixelation, and Euclidean color-distance quantization happen locally inside your active web browser window. Your images are never uploaded, stored on external servers, or tracked.
Why did my LEGO Pick a Brick (PAB) export split into multiple files?
The official LEGO Pick a Brick system limits a single upload list to a maximum of 999 parts. If your custom mosaic requires more than 999 bricks, Bricksly automatically splits your order into sequential, optimized JSON lists. Simply upload these files to the LEGO Pick a Brick tool one by one to complete your full parts list.
Why is my browser asking for permission to download multiple files from Bricksly?
When your mosaic exceeds 999 parts, our tool generates multiple numbered JSON lists simultaneously to accommodate LEGO's upload limits. To protect you, web browsers require you to manually approve bulk file downloads. Click "Allow" or "Yes" when prompted, and your files will download in the exact chronological order needed for your upload.
How do I import the generated XML file into a BrickLink Wanted List?
- Log into your BrickLink account and click your profile icon in the top right corner.
- Navigate to My Wanted List > Upload and choose Upload BrickLink XML format.
- Open your downloaded
bricksly-wanted-list.xmlfile and copy all text contents starting directly with the<INVENTORY>tag. - Paste the clipboard data into the entry box, then click the blue Proceed to verify items button.
How do I fix the BrickLink error 'Invalid File Format: Content is not allowed in prolog'?
This common XML troubleshooting error happens when extra browser styling text is accidentally copied alongside the raw data. To fix it, ensure your pasted clipboard text starts immediately with the opening <INVENTORY> tag, deleting any introductory text lines about 'style information associated with it' before hitting verify.
What type of image works best for the mosaic generator?
High-contrast images with strong lines and minimal background clutter yield the best physical results. Portraits, graphic logos, and pixel art scale exceptionally well into 1x1 studs. Complex, highly detailed landscape photos may require the maximum 128-stud canvas width to render legibly.
The Mosaic Designer’s Field Manual
Brickapic is a custom brick mosaic engine built for the community. We turn standard digital photos into clean, physical 1x1 brick blueprints without the commercial guesswork.
01 How to Build Your Mosaic Blueprint
Upload a High-Contrast Picture
Select a high-resolution file directly from your device. For the cleanest downsampling results, pick images with bold lines, strong shadows, and minimal background clutter. Portraits, retro pixel art, and graphic logos perform the best.
Balance the Resolution Slider
Adjust your grid dimension to fit your physical wall layout. The slider increments on a strict base-16 configuration to align perfectly with standard elements. A lower width creates retro pixel vibes, while a max width captures intricate details at the cost of a higher brick count.
Choose Molds & Baseplates
Toggle between classic square tiles, rounded studs, or SNOT mosaic alignments. Select either standard 32x32 plates or large 48x48 backings. The preview will immediately re-render a grid overlay showing you exactly where the seams will sit on your physical workbench.
Export Your Build Sheet
Hit the download button to generate a clean, multi-page layout manual. The generator bundles a complete inventory checklist showing exactly how many 1x1 pieces you need to source from your local parts bins, BrickLink, or Pick a Brick.
Color Quantization: Turning Pixels into Physical Bricks
Most generic internet pixelators just blow up your image and throw basic web colors at the screen. Brickapic is a true color design tool calibrated to actual factory palettes. When you select a specific stud style, the internal script filters out every single paint option that does not exist for that physical part mold.
The engine scans the raw RGB data of your picture pixel by pixel and runs a three-dimensional Euclidean color distance calculation. It maps the red, green, and blue values of your photo against the exact light absorption signatures of physical ABS plastics. The pixel instantly snaps to the closest structural match. If a specific color variation was never manufactured as a 1x1 round tile, the math drops it completely, saving you from drafting unbuildable designs.
When you download the instruction manual, the system slices your design into separate modular quadrants. Each plate page overlays a high-contrast alphanumeric marker onto the layout grids. The code automatically measures the optical brightness of the chosen background tone. Dark elements get clear white numbers, and light elements get dark ink, keeping the grid readable under warm room lighting on your building table.
Absolute Local Privacy
Your pictures never leave your personal computer. Every single line of color mapping, resolution sampling, and map calculation runs inside your active browser window.
We do not upload your content, store personal uploads on remote servers, or run analytical image scraping trackers. It is your art, your workspace, and your hardware doing the heavy lifting.
Zero Paywalls. No Catch.
Brickapic is entirely free to use. There are no locked resolution options, no hidden feature micro-transactions, and no account registrations required to download your printable manuals.
This tool is built out of pure fan passion to make custom mosaic design accessible to casual builders and master collectors alike. If you have the storage bins and the baseplates, you are ready to create.

Instant BrickLink Sourcing
Sourcing hundreds of tiny 1x1 elements manually is the most tedious part of any custom build. The BrickLink XML export solves this instantly by formatting your exact inventory into an industry-standard upload file.
Simply drop that downloaded file directly into the Mass Upload page on BrickLink. It will automatically populate a private Wanted List with the precise part IDs, factory color codes, and exact quantities required—no manual data entry or scrolling through store catalogs required.
