SRT/VTT Subtitle Editor

Note: NOTE/STYLE/REGION blocks in VTT files are skipped on import — counted and reported, not preserved.

⚠ Some cues overlap in time — check the highlighted rows.

How to edit subtitles

1. Import — drop a .srt or .vtt file above. The format is detected automatically.
2. Edit — change text directly in each cue; click a timestamp to fix timing (HH:MM:SS,mmm).
3. Adjust — shift all cues by milliseconds, merge, split, renumber, or search & replace.
4. Export — download as .srt or .vtt. VTT exports include the WEBVTT header.

Features

• SRT and VTT import with automatic format detection
• Per-cue text and timestamp editing with validation
• Overlap detection, start-before-end enforcement
• Shift all timestamps ±ms, renumber, merge, split, search & replace
• Malformed files: clear per-line errors, good cues still load
• Export to clean .srt and .vtt
• Works on phones — touch-friendly, no horizontal scroll at 375px

Honest limits

• No auto-transcription, no translation, no automatic audio/video sync.
• VTT STYLE, REGION and NOTE blocks are skipped on import (the count is reported).
• Styling tags like <i> are kept as plain text, not rendered.
• Very large files (10,000+ cues) will load but may feel slow on low-end phones.
• Files over 5MB are refused.
