Six common build types that come out of BlockForge, with the palette and size that work best for each. Use these as starting points, not rules.
The most popular use of BlockForge. Crop the source photo tight to the face, drop background out if you can, set the output to 128 by 128 or 256 by 256. The wool and concrete palettes give you the cleanest skin tones. Terracotta works for warmer, painterly results. Build it on a flat wall with at least one block of air behind you so you can step back and verify the proportions as you go.
Logos convert best from a high-contrast source: an SVG export or a PNG with a transparent background and clean edges. Use the wool or concrete palette for sharp, flat color output. 64x64 works for small logos; go to 128x128 if the logo has fine detail or multiple colors that need separation.
Logos with gradients or anti-aliased edges lose that detail at block resolution. The cleaner the source, the crisper the result. If the original logo has a drop shadow or glow effect, remove it before uploading. Solid fills with clear outlines convert almost perfectly. This makes BlockForge a good fit for server spawn lobbies and esports team banners, where a clean logo reads from a distance.
Use the official Minecraft mob textures as the source so the output looks intentional, not like a bad photo conversion. The original mob textures are already pixelated and high-contrast, which means they convert at a 1:1 ratio without any information loss. 32x32 or 64x64 is plenty for mob faces.
Stick to the wool-only palette for mob art. The flat colors in the original textures match wool colors well, and the result looks clean and recognizable. Classic mob faces, Creeper, Enderman, Pig, Zombie, work especially well because the original 64x64 textures have very few distinct colors and strong outlines. These make great wall decorations in mob-themed builds or adventure map dungeons.
Landscapes need room to breathe. Use 256x256 or larger to preserve detail across the whole scene. The full block palette works best here because the variety of textures helps create a painterly, layered look that a single material category cannot replicate.
Landscape photos with a clear sky, horizon, and ground plane convert especially well. The sky becomes a field of light blue and white wool or concrete, the midground picks up greens and browns from terracotta and leaves, and the foreground gets the richest variety. Reduce the output size slightly below what the detail suggests, forcing a bit of block-level abstraction rather than trying to faithfully replicate every pixel. This is one case where the conversion imperfection becomes part of the style. Aim for about 70-80% of the pixel dimensions of the source for the best balance between fidelity and blocky character.
Existing pixel art from games converts at its best when the output dimensions match the source pixel dimensions exactly. A 16x16 sprite should output at 16x16 blocks. A 32x32 sprite at 32x32. This 1:1 mapping means every pixel in the source becomes exactly one block, with no interpolation or blending.
Use wool-only or concrete-only palette for pixel sprites to keep colors crisp and avoid the matcher introducing unrelated blocks from other categories. Small sprites like 16x16 to 64x64 are fast to build and look sharp at those exact sizes. Classic retro game characters, indie game sprites, and icon-style art all work well. These are popular for decorating the walls of a game room build or recreating iconic characters in a fan-tribute world.
Map art in Minecraft lives on the in-game map item, which renders a 128x128 block area at ground level. Set your BlockForge output to exactly 128x128 and use the full block palette for the best color accuracy. The Minecraft map renderer has its own color palette based on block types, so using more block types gives the map more distinct colors to work with.
Place the schematic flat on the ground, not on a wall. The map item renders XZ plane blocks, not vertical walls. Build at least 64 blocks below the world's build height and in a flat open area so the map renders cleanly without neighboring structures bleeding into the image. Once placed, hold a filled map over the area to see the rendered result. Litematica's floor placement and the 128x128 output dimension together make this the most precise use case BlockForge supports.
