Can this convert every Java resource pack to Bedrock perfectly?

No. The converter handles common resource pack metadata and texture folders, but Java-only systems such as OptiFine CIT, CEM, shaders, and complex item models usually need manual work.

Does the pack converter upload my files?

No. Conversion runs in your browser with JSZip. The selected pack is read locally and the converted output is generated locally.

What file types are supported?

The tool supports Java resource pack .zip files and Bedrock .mcpack or .zip files. Output is either a Java .zip or a Bedrock .mcpack.

What this converter can and cannot do

Minecraft Java and Bedrock packs use different metadata and texture paths. This tool handles the useful baseline conversion: pack metadata, pack icons, and common texture folders. It does not pretend to perfectly translate OptiFine CIT, CEM models, shaders, Java item models, Bedrock render controllers, or behavior-pack logic.

Java -> Bedrock

Creates manifest.json, generates UUIDs, maps assets/minecraft/textures/block and item into Bedrock texture folders, and exports .mcpack.

Bedrock -> Java

Creates pack.mcmeta, maps textures/blocks and textures/items into Java texture folders, and exports a Java-ready .zip.

Java Update

Copies the Java pack and rewrites pack.mcmeta with your selected pack_format for newer Minecraft versions.

Pack Converter FAQ

Can it convert every pack perfectly?

No. It handles common texture and metadata conversion. OptiFine CIT, CEM models, shaders, custom Java models, Bedrock render controllers, and behavior logic usually need manual edits.

Do my files get uploaded?

No. The converter runs locally in your browser using JSZip. It reads your archive, builds a new archive, and downloads it without sending the pack to a server.

Which formats should I upload?

Use .zip for Java packs and .mcpack or .zip for Bedrock packs. The output is .mcpack for Bedrock or .zip for Java.
