About this character counter
Count Unicode characters, UTF-16 units, and UTF-8 bytes. Unicode code points are counted individually; whitespace is excluded from the second count. UTF-8 bytes measure encoded size. Work directly with your own text in this browser without signing in or uploading a document. Review the result before copying it into another application, and use Reset to clear the workspace when you are finished. The examples below show the exact behavior to expect, while the limitations explain cases where another workflow may be more suitable.

Inputs and results stay in this browser. Only tool identifiers are stored for your recently used tools. You can clear that history from the directory.
