About mcworld.app
mcworld.app is an independent, third-party iOS tool that spans the whole lifecycle of Minecraft world files: creating, repairing, converting, protecting, and deploying. Create worlds from real-world maps, repair saves that won't open, convert across editions (Java Edition → Bedrock), protect worlds with snapshots, and deploy them safely to a server — or even spin one up in a single tap.
The product principles we hold to
- Diagnose before you pay. File diagnosis is free and runs on your device by default. See the quality score and a 3D preview before you generate, and check the compatibility rating before you convert.
- Never overwrite your source files. Repairs, conversions, optimizations, restores, and deployments all produce a new version; the original file is preserved alongside its hash, so everything stays traceable.
- Verifiable results. Every step comes with structural validation and a readable report, and any paid task that fails is refunded automatically.
- Honest about the limits. We never promise "100% lossless" conversion — we list, item by item, what might change.
Who it's for
Creators who want to turn their city, neighborhood, or favorite landmark into a Minecraft world; players wrestling with corrupted saves, edition mismatches, or worlds that just won't import; and server owners who need to update live worlds safely and get a server running fast.
