🎬 Video Subtitle Creator & SRT/VTT Editor

What is this tool?

This free subtitle tool lets you create, edit and convert subtitle files (SRT and VTT) right in your browser, and optionally burn them into any video. Import an existing caption file, fix the timing, convert between formats, or build subtitles from scratch against a video preview.

How to use:

• Import: Load an existing .srt or .vtt file to edit it - no video required
• Edit: Add, duplicate or delete cues and adjust each start/end time and text
• Shift & fix: Shift every cue by a set offset, sort & renumber, and validate timing for overlaps
• Convert: Export your subtitles as SRT or VTT in one click
• Preview: Optionally upload a video to position and preview captions in real time
• Burn (optional): Click "Burn Subtitles to Video" to hard-code captions into the video

Features: SRT/VTT import & export, format conversion, timing shift with clamping, overlap validation, sort & renumber, visual timeline editor, real-time preview, and per-subtitle styling. Everything runs in your browser - your files never leave your computer!
