About this tool
Count characters, non-space characters, words, lines, and UTF-8 bytes. Byte size uses TextEncoder.
How to use: paste text, copy the stats. Surrogate pairs count as two UTF-16 code units in the character total.
Example: a JSON payload shows whether it fits an env var. Related: hash generator if you needed a digest instead of a size.
