How to Design Minecraft Pixel Art from Scratch in Blockmatic

Blockmatic is a browser-based Minecraft pixel art editor and image converter. You can design from scratch by starting with a blank canvas, painting pixels with Minecraft block colors, and then saving or exporting the result. This guide covers the canvas workflow, block color selection, editing tools, and how to finish your piece. It assumes you have a browser and can reach blockmatic.trafficlunar.net; no image file is required.

Start with a blank canvas

The editor is built around a pixel grid where each cell represents one block. To design from scratch, you skip the image-upload path and work directly on the grid.

1. Open Blockmatic in your browser.
2. Choose the blank/new canvas option rather than uploading an image.
3. Set the canvas dimensions to match your intended build. Minecraft pixel art is usually planned in blocks, so a 32×32 or 64×64 grid is a common starting point for a wall mural or floor design.
4. Confirm the size to generate the empty grid.

Expected result: an empty pixel grid you can paint on, with each cell standing for one Minecraft block.

Choosing a canvas size

Larger grids give more detail but take longer to fill and are harder to keep consistent. Start smaller than you think you need.

Paint with Minecraft block colors

Each pixel is filled with a block color, so the palette is the core of the tool. Instead of picking arbitrary RGB values, you select from Minecraft block colors so the design maps cleanly onto real blocks in-game.

• Open the color/block palette.
• Pick a block color for the area you want to paint.
• Click or drag on the grid to fill cells with that block.
• Switch colors as you move between regions of the design.

A useful habit is to block in large flat areas first (sky, background, base color) and add detail colors afterward. This keeps the palette manageable and makes the structure readable before you refine it.

Selecting and replacing colors

To change a color you already used, select the new block color and paint over the existing pixels. If you want to swap one block type for another across a whole region, select the region first and then apply the replacement color, rather than repainting pixel by pixel. This is the fastest way to test palette variations without redrawing the art.

Edit, erase, and adjust pixels

Designing from scratch is iterative, so plan to revise.

• Erase: use the eraser tool to clear individual pixels or a dragged area back to empty.
• Undo/redo: step backward and forward through your edits when a change doesn't work.
• Adjust: repaint over pixels to fix colors, or clear and redraw a section that isn't reading well.

A practical check is to zoom out periodically. Pixel art that looks correct up close can lose its shape at a distance, and Minecraft builds are usually viewed from far away.

Save or export your finished art

When the design is complete, use the save or export option to keep the result. Depending on the tool, this produces a file or a shareable output you can reference while building in Minecraft.

• Save your work before closing the tab so you don't lose the grid.
• Export the finished piece to keep a copy or to use as a build reference.
• If you plan to build it in-game, keep the export visible while placing blocks so you can match colors and positions.

Common snags when starting from scratch

• Grid too large: detail becomes hard to manage. Reduce the size and work up.
• Too many colors: the palette gets muddy and the build is harder to source. Limit yourself to a small set of block colors.
• No distance check: zoom out regularly to confirm the design reads at Minecraft viewing distance.
• Losing work: save or export before you close the editor.

If you already have a reference image, converting it is faster than drawing by hand; designing from scratch is the better choice when you want full control over the palette and layout.
