WorldSwitch

Overview

WorldSwitch accepts Bedrock and Java worlds and supports edition, version and format conversion in either direction. It aims to carry over terrain, blocks, inventories, player data, mobs, supported block entities, maps, biomes and commands. That is substantial coverage for a standard world, but not a full migration: mods, data packs, behavior packs, resource packs, statistics, advancements and terrain that has never been explored do not transfer.

The conversion runs on the service’s server after you upload a world through your browser, so there is no software to install. The limit is 10 GB for an unpacked world, and the uploaded file itself must also be no larger than 10 GB. The maker says files travel over HTTPS encrypted in transit; access ends 24 hours after conversion, when deletion is triggered. That offers a defined retention window, though it still means uploading a world to a remote service.

Key features

Broad built-in content coverage

The detailed reference spans 152 entity types, 42 enchantments and 45 potion variants. That breadth should matter to players whose worlds contain more than basic terrain and blocks. It does not remove the need to check the exclusions: custom content from mods or packs is outside the conversion scope.

Commands handled with a fallback

Vanilla command syntax is translated between editions. Commands with no equivalent are disarmed and reported rather than silently treated as supported. This is a sensible safeguard, but players who rely on edition-specific command behavior should expect to review the result.

Pricing

WorldSwitch charges once per conversion according to uploaded file size, rather than requiring a recurring subscription. The free Mini plan costs €0.00 per conversion for files up to 70 MB and requires no sign-up, making it a practical first choice for small worlds.

Small costs €1.99 per conversion for files from 71 MB to 300 MB. Medium costs €3.99 per conversion for files from 301 MB to 1 GB. Large costs €7.99 per conversion for files above 1 GB, up to the 10 GB world ceiling. Each paid tier buys capacity for a larger file, not a different conversion feature set. The one-time charges suit occasional migrations better than a subscription, but repeated conversions can add up. The paid service is intended for consumers converting worlds for private purposes, not professional use. Payments go through Stripe, with payment methods shown at checkout.

Platforms

WorldSwitch is a web service. The browser workflow avoids installing a desktop tool, while server-side processing means the world must be uploaded and stay within the file limit.

Who it's for

Choose WorldSwitch for a private Bedrock-to-Java or Java-to-Bedrock migration when the world is within the size cap and its important content is part of the supported conversion scope. It is less suitable when a world depends on mods or packs, when statistics and advancements must be preserved, or when unexplored terrain needs to move over.

Pros and cons

• Pros: Converts between Bedrock and Java, including versions and formats, through a browser without installation.
• Pros: Covers a wide range of built-in world content, with command handling that reports commands lacking an equivalent.
• Pros: The free tier covers files up to 70 MB, and larger-file fees are one-time rather than recurring.
• Cons: Mods, packs, statistics, advancements and never-explored terrain are excluded, which can leave a converted world incomplete.
• Cons: Every upload is capped at 10 GB, including the uploaded file itself; larger worlds cannot use the service.
• Cons: Paid conversion is limited to private consumer use, and repeated conversions incur another charge each time.

Verdict

WorldSwitch is a strong fit for players converting a private, conventional Minecraft world who value a browser workflow and broad support for built-in content. The free small-file tier and transparent one-time size bands make occasional use straightforward. Look elsewhere if the world relies on excluded packs or progress data, exceeds 10 GB, or the conversion is for professional use.
