# HuggingFace Tokenizers - Fast Tokenization for NLP
Fast, production-ready tokenizers with Rust performance and Python ease-of-use.
## When to use HuggingFace Tokenizers
**Use HuggingFace Tokenizers when:**
- Need extremely fast tokenization (<20s per GB of text)
- Training custom tokenizers from scratch
- Want alignment tracking (token → original text position)
- Building production NLP pipelines
- Need to tokenize large corpora efficiently
**Performance**:
- **Speed**: <20 seconds to tokenize 1GB on CPU… load the full skill through Skill Me
