❓ FAQ

Why are multiple candidates shown?
Mojibake can arise from multiple paths and cannot always be uniquely identified. We score candidates by Japanese character frequency and rank them.
Is my input sent to a server?
No. We load encoding.js from a CDN and decode entirely in your browser. Text is never transmitted.
Can I load a Shift_JIS or EUC-JP file directly?
Currently only text paste is supported. For full file encoding conversion use the Line Endings & Encoding tool.
