⚡ByteBack⚡is a browser-based PWA for recovering text damaged by encoding errors. Paste mojibake, a wrong keyboard layout, transliteration, HTML entities, escape sequences, URL encoding, or Base64. ByteBack tests possible repair chains, ranks readable results, and shows each transformation step plus before-and-after changes. Processing happens on your device: pasted text is not uploaded, stored, or used for tracking. Install it for offline use in multiple languages.
