Block Round

Block Round is a browser-based generator for Minecraft-textured circles, ellipses, spheres and ellipsoids. It is a strong fit for builders who want to move from a chosen shape to a PNG or schematic without installing software or creating an account. Its useful range of shapes and export paths comes with one recurring inconvenience: settings return to their defaults after a reload.

Overview

The tool handles both 2D figures and 3D forms, with a 3D preview and exports geared to different tasks: PNG files for flat figures and Sponge schematic v2 files for 3D figures. That makes it practical for builders who want to take a generated shape into another editing tool, rather than stop at a visual preview. Browser access requires no installation, account or backend, and the app can work offline as a PWA.

The session-only settings are the clearest limitation. A one-off user can generate a shape and leave; anyone returning to a recurring project must set preferences again. That trade-off is easier to accept for occasional building than for a workflow built around repeated variations.

Key features

• Three 2D algorithms: Circle and ellipse modes offer Euclidean, Bresenham and Threshold algorithms. Having alternatives gives builders a way to choose among different block layouts instead of being locked to one generation method.
• Minecraft block selection: The picker includes Grass Block, Dirt, Stone, Oak, Diamond, Sand and Gravel, alongside a Random mix and other blocks. This lets users vary the material appearance directly in the generator.
• 3D shapes and cuts: Sphere and ellipsoid modes support X, Y and 45-degree diagonal cuts. These options add flexibility for builders shaping 3D forms, while the 3D preview helps keep the work oriented as a spatial object.
• Two export paths: PNG export suits sharing or keeping a 2D figure as an image. The Sponge schematic v2 export is the more useful choice when the aim is to continue editing a 3D figure; it can be imported by WorldEdit, Litematica and MCEdit.
• Offline-capable browser app: The app works offline as a PWA and has no backend. That suits users who want a lightweight browser workflow, though the settings still do not carry over after reloading.

Pricing

Block Round is free to use for its core job, with a Free plan priced at $0. There is no paid tier required to generate the supported shapes or export PNG and schematic files. That makes it a straightforward choice when a builder needs this focused tool without a subscription; the main compromise is the loss of saved preferences between sessions, not a paid-plan gate.

Platforms

Block Round is available on the web. Its browser-based, no-install setup and offline PWA support suit people who prefer not to install a separate application, while the session-only settings make it less convenient for ongoing projects with repeat configurations.

Who it's for

Block Round is best for Minecraft builders who need circles, ellipses, spheres or ellipsoids made from block textures and want to export the result for further use. It is particularly useful when the next step is an image for a 2D figure or a schematic for a 3D build. Someone who mainly needs a small circle, wants a different platform, or values saved settings may prefer to compare other tools.

Pros and cons

• Pro — Flat and 3D shapes in one tool: Circles and ellipses sit alongside spheres and ellipsoids, covering more than a single shape-making task.
• Pro — Practical export choices: PNG and Sponge schematic v2 exports serve image and editing workflows, and the schematic is compatible with WorldEdit, Litematica and MCEdit.
• Pro — No account or installation: The browser app has no backend and can work offline as a PWA, reducing setup for occasional use.
• Con — Preferences do not persist: Reloading resets settings to defaults, adding repeated setup for builders working across sessions.
• Con — Web-only: The platform choice does not suit users specifically seeking an Android or iOS app.

Alternatives

For other options, see Minecraft Shape Generators. Choose Mcgic Circle Generator instead if a browser, Android or iOS circle tool is a better fit and its 512 × 512-block size ceiling and full-block output meet your needs. Minecraft Plot is another freemium option across web, Android and iOS, with a free tier of basic tools and paid premium membership. Choose Astroworld Circle & Dome Generator if a web tool with no sign-up or ads and a 1–256 block diameter range suits the task. Block Shape Generator offers sphere, cone, dome and cylinder controls in a free web tool. BlockBlend may suit builders seeking unlimited palettes, all blocks, WorldEdit export and community sharing. CartoVoxel Minecraft Shape Maker offers 11 shapes, live 3D and layer views, and JSON, layer guide and Java mcfunction exports. MC Circle is a free web option for circles from 3–128 blocks, with Java and Bedrock support. MC Circle Generator offers circle and oval layouts with PNG and SVG export.

Verdict

Choose Block Round if you want a free browser tool that covers both 2D and 3D Minecraft-textured geometry and can export a schematic for continued editing. Its combination of shape types, material choices and export formats is the main reason to pick it. Look elsewhere if you need persistent settings or a mobile app; returning to defaults is a meaningful nuisance for repeated work.
