Subtitle Doctor

Subtitle Doctor is a free MIT-licensed offline Windows utility by ALMARFELD. Inspect SRT, ASS, SSA and WebVTT; preview repairs, edit cues, adjust offsets/FPS, convert formats and export reports. v1.0.1 preserves balanced tags during split/wrap and refuses incompatible merges. No video preview, translation or speech timing detection. Advanced styling can be lost on conversion; review exports. Unreadable blocks and invalid timing block export. Originals are preserved by default; optional replacement needs confirmation and a backup. Undo is session-only. Windows 10/11 x64 portable ZIP: extract fully and run SubtitleDoctor.exe. Separate Microsoft Edge WebView2 Runtime required; nothing installs automatically. No accounts, uploads or telemetry. The executable is not Authenticode signed.
