About this tool
Editing a resource pack normally means unzipping it, hunting through hundreds of folders, editing PNGs in an image program, and zipping it back with the right structure. This tool does the plumbing: drop the zip and every texture appears in a filterable list; click one and it opens in the pixel editor at its true size, with a part guide-free 16 × 16 grid, palettes, mirror, layers, and noise brushes; switching textures saves the previous one into the pack. Add new textures at any path (the list suggests common block, item, entity, and GUI paths), update the description and pack_format for your game version, and download a zip that Minecraft accepts as is.
It also works from scratch: start a new pack, add the textures you want to override, and download. The zip keeps every non-texture file from the original (models, sounds, language files, and animation .mcmeta files) untouched.
How to use it
- Drop an existing resource pack zip, or start a new pack.
- Pick a texture from the list to open it in the editor; draw with the pencil, fill, layers, and noise brushes, then switch to the next one. Changes are kept in the pack.
- Add missing textures by path, set the game version, and download the zip. Drop it in .minecraft/resourcepacks.
Questions
Which pack_format do I need?
It depends on the game version; the version list sets it for you. Packs with an older format still load with a warning; a newer format than the game knows is rejected.
Can it edit textures bigger than 256 pixels?
The editor handles up to 256 × 256, which covers blocks, items, most mobs, and GUI elements. Larger ones (title screens, some 512 × 512 HD packs) can be exported, edited elsewhere, and re-added.
Does it keep animation and model files?
Yes. Everything that is not a PNG passes through untouched, including .mcmeta animation files next to textures, models, sounds, and fonts.
Where does the pack go?
Put the downloaded zip in .minecraft/resourcepacks (the game's Resource Packs screen has an Open Pack Folder button), then enable it in the list.
