String Counter

What is this tool?

This string counter measures text length from several practical angles: total characters, characters excluding whitespace, words, lines, sentences, and UTF-8 byte size.

Different limits count different things. A UI field may limit characters, a database column may limit bytes, an editorial brief may limit words, and an API may care about encoded payload size. Non-ASCII characters can use multiple UTF-8 bytes even when they appear as one visible character.

Use it for metadata, social copy, validation rules, translations, database fields, API payloads, and any workflow where exact text length matters.

How to use

1. Paste or type text into the input area.
2. Read the live statistics for characters, characters without spaces, words, lines, sentences, and UTF-8 bytes.
3. Use byte count when the target limit is storage or API based.
4. Copy the stats summary when you need to record the measurement.
