Words ↔ tokens, both directions.
Type in either field and the other updates instantly. Handy when you only have a word count from a brief, or a token budget from a model card (32k, 128k, 1M) — not the final paste yet. For OpenAI, tiktoken, Claude, or ChatGPT length on real text, use the live token counter instead.
Ratios are approximate — about 1 token per ¾ of an English word. Actual counts vary by model and language; paste real text into the token counter for a closer estimate.
Common lengths
How the ratio works
English text averages roughly 4 characters per token, which works out to about 1 token for every ¾ of a word. This converter uses that single ratio, so it's a planning shortcut — not a substitute for a real tokenizer. Code, punctuation-heavy text, and non-English languages can differ substantially.

Good uses for this page
You only have a word count from a doc or brief, not the final paste yet.
A model card lists 32k, 128k, or 1 million tokens and you want a reading-length intuition.
You need a ballpark token budget before drafting, or a word estimate for writers who think in pages.
You want a quick ratio check — then verify with the live counter when you have the string.
