Resource Pack Converter

Input

Drop a pack here

.zip plugin pack, Java resource pack, or .mcpack Bedrock — max 300MB

Convert between ItemsAdder, Nexo, Oraxen, CraftEngine, MythicCrucible, and vanilla resource packs. Upgrade or downgrade Java packs (1.8.9 through 26.1+), or pick a Bedrock 1.19+ target for a .mcpack plus Geyser mappings v2. Also converts items/blocks/armor 2D+3D, shields, bows, ModelEngine 4, BetterModel, DisplayEntity, and Scoreboard Logo assets.

Result

Load a pack, choose a pack type and target version, then convert.

Supported assets

Source packs are auto-detected. Convert between these layouts (and still retarget Java versions or export Bedrock):

Vanilla Resource Pack — pack.mcmeta + assets/
ItemsAdder — contents/<namespace>/configs + resourcepack
Nexo — items/ YAML + pack/assets
Oraxen — items/ YAML + pack/ textures and models
CraftEngine — resources/<namespace>/configuration + resourcepack
MythicCrucible — pack items YAML + assets/

Java version converts and Bedrock / Geyser exports also cover:

Items, blocks, and armor in 2D and 3D (cube models → Bedrock geometry + attachables)
Shields, bows, crossbows, fishing rods, tridents, elytras, and spears
Animated textures (Java .mcmeta → Bedrock flipbooks)
GUI, fonts, sounds
ITEM_MODEL (assets/*/items, pack format 46+) and legacy custom_model_data
Automatic 3D inventory icons from the model’s primary texture
Geyser mappings v2, including merge of existing mapping JSON
ModelEngine 4, BetterModel, DisplayEntity, and Scoreboard Logo packs

Plugin zips unwrap into the plugin folder (ItemsAdder/contents/…, Nexo/pack/…, and so on). Bedrock exports include geyser_mappings.json to drop into Geyser’s mappings folder. Copy the .mcpack into Geyser’s packs folder.

API usage

Programmatic converts for packs up to ~4MB:

GET  /api/pack-convert
POST /api/pack-convert
Content-Type: application/json

{
  "packBase64": "<base64 zip>",
  "to": "1.21.1",
  "from": "1.8.9",
  "packType": "nexo"
}

packType can be vanilla, itemsadder, nexo, oraxen, craftengine, or mythiccrucible. Bedrock targets use ids such as bedrock-1.19 or bedrock-1.21. Larger packs should use this page — conversion stays on-device.
