FAQ

Is this tool free?

Yes — it is completely free to use, with no account or sign-up required.

What is this tool?

Open a text or CSV file saved in a legacy encoding (like Korean EUC-KR/CP949 or Japanese Shift_JIS) and convert it to UTF-8 — or the other way around. Pick the source encoding (or let it auto-detect), preview the decoded text to confirm it reads correctly, choose a target encoding and download the re-saved file. Choosing “UTF-8 + BOM” makes a CSV open without garbled characters in Excel. Everything is processed in your browser, so your files are never uploaded, and it is free with no install.

Are my uploaded files sent to a server?

No. Everything runs only on your own computer, inside your browser, and your files are never sent to a server or anywhere else. So you can use it with complete peace of mind, without worrying about your file contents leaking.
