Character Encoding Detector

Detect the character encoding of any text or file, convert between encodings, and fix mojibake — all client-side. Supports UTF-8, UTF-16, ISO-8859, Windows codepages, Shift_JIS, EUC-JP, GBK, Big5, KOI8-R, and more.

How to Use

Paste text or upload a file to detect its encoding. The tool analyzes byte patterns and displays possible encodings ranked by confidence. Switch to Convert mode to re-encode text between character sets, or use the Mojibake Fix mode to repair garbled text by specifying the original and misinterpreted encodings.

Features

  • Multiple encoding support – UTF-8, UTF-16, UTF-32, ISO-8859-1 through 15, Windows-1251/1252, Shift_JIS, EUC-JP, GBK, Big5, KOI8-R, ASCII
  • Encoding conversion – Convert text between any supported encodings with downloadable output
  • Mojibake fix – Repair incorrectly decoded text by specifying source and target encodings
  • File upload – Drag and drop or browse to analyze text files
