Compteur de caractères, lignes et octets en temps réel

Whether you are crafting concise copy for advertising headlines, optimizing blog meta tags, or ensuring academic papers adhere to strict editorial guidelines, our free character count tool and letter counter gives you immediate, accurate text telemetry. As you type or paste content into the analyzer, the engine computes full metrics across raw characters, alphabetical letters, whitespace, digits, and punctuation symbols with zero latency.

Understanding the difference between total characters and true letters is crucial for professional publishing. While a standard character counter tallies every keystroke (including spaces, emojis, and punctuation marks), a letter counter isolates only the alphabetical letters (A-Z and a-z). Furthermore, our tool calculates UTF-8 byte sizes, which is vital for database developers, software engineers, and international language translators dealing with multi-byte unicode characters.

Our character count tool also features built-in limit monitors for top digital platforms—including X (formerly Twitter with its 280-character ceiling), LinkedIn posts (3,000 characters), SMS text messages (160 characters), and search engine optimization snippets (60 characters for titles, 160 characters for meta descriptions). All operations occur strictly on the client side, meaning your confidential drafts and notes are never stored or transmitted over the internet.
