Features

• Inspect SRT, ASS, SSA and WebVTT subtitle files
• Preview selectable subtitle repairs before saving
• Split and wrap balanced formatting without breaking tags
• Refuse merges with incompatible timing, metadata or formatting
• Adjust offsets, two-point synchronization and FPS
• Export new subtitle copies and JSON/CSV reports

Limitations and safety

Cross-format conversion can lose advanced styling, positioning, karaoke, CSS and regions. No translation, video preview or waveform. Splits use word boundaries and timing midpoint, not speech recognition. Undo is session-only. Unreadable blocks and invalid timing block export. Originals are preserved by default; optional replacement requires confirmation and a backup. Encoding detection beyond UTF-8/BOM UTF-16 assumes Windows-1252 with a warning.
