Question 1

How do I convert text to tokens?

Accepted Answer

Use our Token Converter to analyze your text and estimate token counts. Tokens are pieces of text - roughly 4 characters or 0.75 words per token. Simply paste your text and the calculator shows token count, word count, character count, sentences, and lines.

Question 2

What is a token in LLM context?

Accepted Answer

A token is a piece of text that LLMs process. It's roughly 4 characters or 0.75 words on average. Different models use different tokenization methods, so actual counts may vary. GPT-4 and Claude use different tokenizers, but our calculator provides a good estimate.

Question 3

How many tokens fit in GPT-4 context window?

Accepted Answer

GPT-4 has a 128K token context window, meaning it can process up to 128,000 tokens in a single request. Claude 3.5 Sonnet supports 200K tokens. GPT-3.5-turbo supports 16K tokens. Use our calculator to check if your text fits within these limits.

Question 4

Why is token count important?

Accepted Answer

Token count determines API costs and context limits. LLM APIs charge per token, so knowing token counts helps you budget. Also, models have maximum context windows - if your text exceeds the limit, you'll need to truncate or split it. Our calculator helps you plan accordingly.

Question 5

Can I upload files to count tokens?

Accepted Answer

Yes! Our Token Converter supports file uploads including .txt, .docx, .json, and .csv files. Upload your document and the calculator will analyze it to show token counts, word counts, and other text metrics. This is perfect for estimating API costs before sending requests.
