✏️ Text Counter

Text counting is essential for any writing that has character limits — college essays, cover letters, social media posts, academic papers, and more. Twitter (X) limits posts to 280 characters, Instagram captions allow 2,200, and most job application forms have strict character limits. This tool shows character count (with and without spaces), word count, and byte count simultaneously, so you can meet any platform requirement.

The built-in spell checker for Korean lets you catch errors while counting. Common Korean spelling mistakes include spacing rules, particle usage, and loanword notation. Running a quick spell check before submitting any formal document — whether a resume, business proposal, or school essay — can significantly improve its professionalism and readability.

Byte counting is particularly useful for technical scenarios like database field limits, SMS messaging, and filename length restrictions. In UTF-8 encoding, Korean characters take 3 bytes while English characters take only 1 byte. This means the same byte limit allows very different character counts depending on the language used. Developers setting input field limits must account for this difference.

Pro tip: Write freely first, then trim to fit the limit. Starting with a tight constraint often leads to underdeveloped content. Instead, write your full thoughts, check the count, then cut unnecessary modifiers, redundant phrases, and overly long sentences. This approach produces denser, higher-quality writing that makes the most of every character.
