What is a Word Counter?
A fast online word counter built for writing, editing, SEO, and publishing
Count Words helps you measure more than just total word count. As you type or paste content, the tool instantly calculates words, characters, characters without spaces, sentences, paragraphs, and estimated reading time. That makes it useful for everything from essays and blog posts to product descriptions, newsletters, and social captions.
Unlike many text analysis tools, Count-Words.com is privacy first. Your text is processed in the browser, not uploaded to a remote server, so you can review drafts, client copy, and sensitive documents without adding another data-sharing step to your workflow.
If you work with files, you can also use our dedicated PDF, DOCX, TXT, Markdown, HTML, and multi-file counters. For quick checks, the main editor remains the fastest way to count words, characters, and sentence totals in real time.
