Minecraft Skins (Parquet)

19,973,824 Minecraft player skins converted from nyuuzyou/Minecraft-Skins-20M (JSONL + zstd with base64-encoded PNGs) to Parquet, with the images decoded to PNG bytes so they load directly as an Image feature.

Structure

80 Parquet files in data/, 250,000 rows each (the last one has 223,824).

Column	Type	Description
id	string	UUID from the source dataset
image	image	PNG bytes (RGBA)
width	int16	Image width in pixels (always 64)
height	int16	Image height in pixels
type	string	64x64 (modern format) or 64x32 (legacy, pre-1.8 format)

type	Rows
64x64	17,001,398
64x32	2,972,426

Processing

• Base64 is decoded to the original PNG bytes; images that were already 64 px wide are stored unchanged (no re-encoding).
• HD skins (wider than 64 px) are downscaled to 64 px wide with nearest-neighbour resampling, keeping the aspect ratio.
• 104 rows with invalid base64 or undecodable images were dropped.
• Row order follows the source files.

Usage

from datasets import load_dataset

ds = load_dataset("javi22/minecraft-skins", split="train", streaming=True)
modern = ds.filter(lambda x: x["type"] == "64x64")
