Free Online Character Counter Tool

OptiDrop's Character Counter is a free, browser-based tool that counts characters, words, sentences, paragraphs, and lines in your text. It also estimates reading and speaking time, making it perfect for writers, students, social media managers, and SEO professionals.

Platform Limit Checks

The tool includes built-in character limit bars for Twitter/X (280 characters), Instagram captions (2,200 characters), meta descriptions (160 characters for SEO), and LinkedIn posts (3,000 characters). The bars change color from blue to red as you approach the limit, helping you optimize your content for each platform.

100% Private and Secure

All counting happens directly in your browser. Your text is never sent to any server, ensuring complete privacy. Use this tool for essays, blog posts, tweets, Instagram captions, meta descriptions, or any text where character count matters.

Frequently Asked Questions

A tweet on X (formerly Twitter) has a maximum of 280 characters. This includes letters, numbers, spaces, punctuation, and emojis. URLs are automatically shortened to 23 characters regardless of their actual length. Our character counter shows a real-time progress bar so you can see exactly how close you are to the limit.
Instagram allows captions of up to 2,200 characters. However, only the first 125 characters are visible before the "more" link is shown in the feed. For Instagram bios, the limit is 150 characters. Our character counter includes an Instagram caption limit bar so you can optimize your posts.
A meta description should be between 120 and 160 characters for optimal display in Google search results. Google typically truncates descriptions longer than 155-160 characters. Our tool includes a meta description limit bar to help you write the perfect length for SEO.
Simply paste or type your text into our free character counter tool above. It instantly displays the character count (with and without spaces), word count, sentence count, paragraph count, line count, and estimated reading time. No sign-up or download required — everything runs in your browser.
