About this tool

Enter a value, choose tokens, words, or characters, and select the language profile that best matches the material. The converter returns an estimated range for rough planning; use Token Counter when you need model-specific tokenization.

Questions & answers

Does this converter use an exact tokenizer?
No. It applies broad language-profile ratios and always presents the result as an estimate.
Why does the result use a range instead of one number?
Tokenization changes with vocabulary, punctuation, scripts, code, and the target model. A range communicates that uncertainty more honestly than a single value.
Which language profile should I choose?
Choose the profile matching most of the content. Use Mixed for multilingual text, prose combined with code, or material with several writing systems.
