Text Encoding Detector & Converter — Fix Garbled Text

Opening a text file created by an older program often shows garbled Korean or Japanese characters. That's usually because the file was saved in a legacy encoding like EUC-KR, CP949, or Shift-JIS, while modern software expects UTF-8 by default.

Upload a file and this tool tries UTF-8, EUC-KR, Shift-JIS, and Windows-1252 in order, automatically finding the encoding that decodes without errors. Check the correctly decoded preview, then download a new file converted to clean UTF-8. Your file is processed entirely in your browser and never uploaded to a server.

It tries UTF-8, EUC-KR, Shift-JIS, and Windows-1252 in order and shows the first one that decodes without errors.

Can it fix garbled files?

Yes — it re-decodes files saved in legacy Korean/Japanese encodings correctly, then lets you download a UTF-8 version.

Is my uploaded file stored?

No. Everything is processed locally in your browser and never sent to a server.
