Three simple steps

How to Use a LEGO Mosaic Maker

The whole process happens in your browser. Your source photo never leaves your device.

For the clearest result, start with a well-lit image where the main subject fills most of the frame. A face, pet, logo, or building with distinct edges usually reads better than a dark or heavily blurred photo. Landscape images work well with the landscape grid presets, while portrait images can use the portrait preset or a custom height.

  1. 1

    Upload

    Choose a portrait, pet photo, artwork, or any clear image.

  2. 2

    Customize

    Set the grid size, palette, and brightness for your build.

  3. 3

    Build

    Download the pattern and use the color quantities as your parts list.

Made for real builds

Private photo processing

Conversion runs locally in your browser. Your image stays on this device while the pattern is generated.

Downloadable brick pattern

Save a high-resolution PNG or print the pattern and parts list as a PDF.

Plan before you build

Choose the right brick mosaic settings

A few simple choices determine how recognizable, large, and easy to build your finished pattern will be.

Crop or fit the whole photo

Crop fills the selected grid and gives the subject the most detail. Use the drag control to move the focal point before generating. Fit keeps the complete image and adds space where the photo and grid have different proportions.

Match the grid to your goal

A 16 x 16 pattern is a quick test or small decoration. A 48 x 48 brick mosaic is a practical starting point for portraits. Choose 64 x 64 or 96 x 96 when viewing distance and fine detail matter more than build time.

Use brightness and palette together

Classic colors give a familiar brick look, soft colors create a gentler illustration, and grayscale emphasizes shape. Adjust brightness when the source photo is unusually dark or washed out, then compare the preview before downloading.

Check the parts list

The generated list counts every color cell in the pattern. Use it to compare what you already own with what you need to buy, and keep the downloaded guide beside your build so each row is easy to follow.

Export for the job

Download a pattern for screens, sharing, or print

Choose Web for a lightweight reference, HD for a sharper zoomable guide, or Print when you want a physical worksheet. Print exports use a selected width and DPI so a 30 cm guide at 300 DPI has enough detail for clear labels and color blocks. Custom pixel width lets you prepare a specific file size for a presentation, craft planner, or archive.

All conversion happens locally in the browser. The original photo, generated grid, crop position, and recent records stay on this device, so you can return to a previous mosaic without creating an account or sending images to a remote service.

From pattern to finished art

Build with a clear, repeatable workflow

The generator is designed to help you move from an idea to a physical mosaic without guessing at colors or dimensions.

Prepare the source image

Use the original file when possible, rather than a screenshot of a compressed image. Keep the subject near the center, remove distracting borders, and choose a photo with enough contrast between the important areas. The preview makes it easy to test several versions before committing to a build.

Preview before you buy bricks

Generate a small grid first to check the crop, brightness, and palette. If the face or logo loses its shape, try a larger grid or move the crop position. This quick check can save time and avoid ordering colors that do not improve the finished design.

Organize pieces by color

Use the parts list as a shopping and sorting checklist. Separate colors into trays, label the downloaded pattern, and build one row or section at a time. For a large wall mosaic, print multiple pages or keep the HD PNG open on a tablet for a zoomed view.

Keep your work on this device

Generation history is stored in browser storage on the device you are using. It is useful for comparing recent attempts, but it is not an online account or cloud backup. Clear the history when you no longer need the records, and download finished patterns you want to keep permanently.

FAQ

Brick mosaic maker questions

Practical answers about image privacy, pattern size, and brick quantities.

How do I make a LEGO mosaic from a photo?

Upload a JPG, PNG, or WEBP image, choose a grid size and palette, then select Generate mosaic. Download the finished pattern and use the parts list to plan your build.

Is this brick mosaic maker free?

Yes. The tool is free to use and does not require an account. You can download your pattern and print the parts list at no cost.

Is my uploaded photo stored?

No. The image is processed locally by your browser and stays on this device.

How many bricks do I need for a 48 x 48 mosaic?

A complete 48 x 48 pattern contains 2,304 cells. The generated parts list shows how many pieces you need for each color.

What is the best size for a brick mosaic portrait?

A 48 x 48 grid balances recognizable facial detail with a manageable build. Choose 64 x 64 or 96 x 96 when you want more detail and a larger finished mosaic.

Should I crop or fit a wide photo?

Choose Crop when the subject matters more than the edges of the photo, then drag the image until the focal point is positioned well. Choose Fit when every part of the wide image matters; the complete photo stays visible inside the grid.

Which download setting should I use?

Web is suitable for quick sharing, HD is best for zooming on a screen, and Print lets you set a physical width and DPI. Use Custom pixels when another app or craft planner requires a specific image size.

Can I use the pattern for a physical LEGO build?

Yes. The color cells are intended as a visual build guide, and the parts list gives the number of cells in each palette color. Confirm the actual brick dimensions and mounting method for your project before ordering pieces.
