Calculate the exact size of any text in characters, words, sentences, paragraphs, and bytes. This tool provides comprehensive text metrics including UTF-8 byte size, character count (with and without spaces), word count, line count, and reading time estimates. Essential for SEO content optimization, character limit compliance, and API payload sizing.
