Java mods and Bedrock add-ons are different systems
Java Edition mod loaders such as NeoForge load compiled Java mods with loader-specific metadata and APIs. Bedrock uses add-on packs and scripting systems designed for its own runtime.
Because the platforms are different, matching a game version number does not create cross-edition compatibility.
Avoid fake “Quark Bedrock” downloads
A file advertised as “Quark Bedrock” is not an official Quark Java mod build. It may be a separate add-on inspired by similar ideas, a mislabeled file or something unsafe.
Do not install repacked executables or archives simply because they use a familiar mod name. Evaluate any Bedrock add-on as a separate project.
What Bedrock players can look for instead
Search for Bedrock add-ons that describe the specific feature you want—building blocks, inventory convenience or decorative changes—rather than expecting a direct Quark conversion.
Keep expectations narrow. A collection of small Bedrock add-ons may recreate some goals, but it is not the same codebase or compatibility model as Quark.
Moving between editions
World and mod data do not transfer cleanly between a heavily modded Java profile and Bedrock. If you switch editions, treat it as a separate setup and preserve backups of the original world.
