Arnis online (unofficial), with nothing to install

Map2Minecraft runs the free, open-source Arnis engine on our servers. Pick a real place on a map in any browser — phone, tablet, Chromebook or PC — and get a playable Minecraft world for Java or Bedrock, with a free preview of the actual result before you pay.

We're not the Arnis project.

Arnis is created by Louis Erbkamm and released free under the Apache 2.0 license. Its only official sites are github.com/louis-e/arnis and arnismc.com, and its official online version is MapSmith. Map2Minecraft is an independent service built on that open-source engine — not affiliated with or endorsed by the Arnis project.

What Arnis is

Arnis is a free, open-source program by Louis Erbkamm that turns OpenStreetMap data and real elevation into Minecraft worlds — Java Edition (1.17+), Bedrock Edition and Luanti. You download it from its GitHub releases, run it on Windows, macOS or Linux, draw a rectangle on its map, and it builds the world on your own computer.

Because it's open source, other services can build on it — that's what we do. If you want the official online version from the same creator, that's MapSmith on arnismc.com. The Arnis team's own guide to the official downloads lists which sites are theirs.

What Map2Minecraft adds on top

The world-building engine is Arnis. The service around it is ours.

Nothing to install

Generation runs on our servers, so it works from any browser — phones, tablets, Chromebooks and PCs, including ones where you can't install software.

A free preview of your actual world

Before you pay anything, you see the world that was really generated: a side-by-side slider of the real map against your Minecraft world, plus a 3D flyover and, on desktop, a street-level walk-around.

Instant download

Most worlds are ready in 1–5 minutes and download the moment you pay, up to 25 km².

Java and Bedrock, straight to your phone

Choose a Java world (.zip) or a Bedrock world (.mcworld). On a phone or tablet you can generate a Bedrock world and open it on the same device, with no computer in between.

Places already scouted

100 city pages with a suggested area for each, from New York to Tokyo, plus guides for small towns, classrooms and servers.

Pay only for what you keep

Generating and previewing are free. Downloading is a one-time price per world, shown before you pay.

Prices to download

Small · under 1 km²$5
Medium · 1–5 km²$10
Large · 5–25 km²$20
Pro · worlds up to 100 km²$39/month or $299/yearunlimited generations, no per-map charge

Generating and previewing are always free. The price for your world is shown on its preview screen before you pay.

See it before you pay

This is what the preview looks like: the real map on one side, the world that was generated on the other. Drag to compare. You get the same view of your own place, free.

Questions

Is Map2Minecraft the official Arnis website?+

No. Arnis is made by Louis Erbkamm, and the project's only official sites are github.com/louis-e/arnis and arnismc.com. Map2Minecraft is an independent service that runs the open-source Arnis engine. We are not affiliated with or endorsed by the Arnis project.

Can I use Arnis online without installing it?+

Yes, two ways. MapSmith (arnismc.com/mapsmith) is the official online version, made by Arnis's creator: you pay first and your world is emailed to you. Map2Minecraft also runs the Arnis engine in the cloud: you generate first, preview the result free, and download straight away if you like it.

Is Arnis free?+

Yes. The Arnis desktop app is free and open source under the Apache 2.0 license — download it from the official GitHub. What you pay for on Map2Minecraft is the hosted service: the servers that build your world, the preview, and the instant download.

Does Map2Minecraft use the real Arnis engine?+

Yes. Our generator is a fork of the open-source Arnis code, adapted to run as a web service, so results can differ a little from the latest desktop release. Credit for the engine goes to Louis Erbkamm and the Arnis contributors.

How much does Map2Minecraft cost?+

Generating and previewing a world is free. To download it: Small (under 1 km²) $5; Medium (1–5 km²) $10; Large (5–25 km²) $20. Pro is $39/month or $299/year: worlds up to 100 km² and unlimited generations.

Does it work on phones and for Bedrock?+

Yes. Everything runs in the browser, and you choose Bedrock (.mcworld) or Java (.zip) before generating. The free Arnis app makes Bedrock worlds too, but it needs a Windows, Mac or Linux computer to run.
