Tokenizer

Tokenizer — see how your text becomes tokens

A free tokenizer that shows how your text gets split into tokens — the small chunks of 1-4 characters that LLMs process. Paste any text to get the exact token count for GPT, Claude, Gemini, and Llama. Tokens drive both API cost and context window usage. Free, instant, in your browser.

Why tokens matter

Every LLM processes text in tokens. More tokens = higher cost (on per-token APIs) and faster context window usage. A typical 1,000-word article is about 1,300 tokens. The tokenizer shows you exactly how your text breaks down so you can optimize your prompts and reduce costs.

Frequently asked questions

How many tokens is my text?

A rough rule: 1 word ≈ 1.3 tokens, 1 English page ≈ 300-400 tokens. Use this tokenizer for the exact count.

How many words per token?

Approximately 0.75 words per token for English. This varies by language and content type.
