What is the difference between characters and bytes?
Characters are individual text units (letters, digits, symbols), while bytes measure the storage size. A single character can use 1 to 4 bytes depending on its encoding.

Frequently Asked Questions
How does this tool count Unicode characters?
This tool uses Intl.Segmenter to count grapheme clusters, which means emoji, combined characters, and CJK characters are each counted as one character regardless of their byte size.
Is my text private?
Yes. All processing happens entirely in your browser. Your text is never transmitted or stored on any server.
What encoding information is shown?
The tool displays UTF-8 byte count, UTF-16 code unit count, URL-encoded length, and the number of unique code points in your text.
Can I use this for social media character limits?
Yes. The tool includes built-in platform limits for Twitter, Instagram, Facebook, YouTube, and more, showing how many characters remain or are over the limit.
