§ Docs How to Use
Enter or Paste Text
Type your content or paste a block of text into the input area. The counter updates immediately as you type.
Select Text Encoding
Choose between UTF-8, UTF-16, ASCII, and UTF-32. The tool recalculates the total byte size dynamically based on the byte layout of the selected encoding standard.
Inspect Metrics & Breakdown
Review the dashboard to see precise word, sentence, line, character, and byte counts. The character breakdown shows exactly what your text is made of (alphabetic, numeric, whitespace, or special/emoji symbols).
? FAQ Frequently Asked Questions
Characters do not always equal bytes. In modern encodings like UTF-8, basic English letters and numbers use 1 byte, accented letters use 2 bytes, symbols like the Euro sign (€) use 3 bytes, and emojis (e.g. 💩) use 4 bytes. This tool accurately encodes your text in binary buffers using standard Javascript APIs to count the exact bytes.
UTF-8 uses a variable layout (1 to 4 bytes per character) and is optimized for ASCII compatibility. UTF-16 represents characters in 16-bit code units (2 or 4 bytes). In UTF-16, standard English characters take 2 bytes instead of 1, which nearly doubles the size of English text.
ASCII is a 7-bit character standard where each character is exactly 1 byte. In ASCII mode, any characters outside the standard 128-character set (like emojis or non-English alphabets) cannot be represented. The tool highlights non-ASCII characters or treats them as invalid (1 byte replacements) depending on standard fallbacks.
