What is Subtitle & SRT Editor?

Subtitle & SRT Editor is an interactive caption studio for creating, editing, synchronizing, and converting `.SRT` (SubRip) and `.VTT` (WebVTT) subtitle files alongside a live video preview. You can upload an existing SRT/VTT file or start from scratch, stamp start/end times directly from the video playhead, shift all subtitle timings forward or backward by milliseconds to fix sync drift, and download clean SRT or VTT files.

How to Use Subtitle & SRT Editor

Load a video and/or subtitle file

Upload a video to preview captions on screen, and import an existing .srt or .vtt file (or load our sample project).

Add or edit caption cues

Edit start times, end times, and caption text in the timeline list, or click '+ Add Cue at Current Time' while watching.

Fix sync drift if needed

Use the Global Time Shift controls (e.g. +0.5s or -0.5s) to nudge all subtitles earlier or later at once.

Export as SRT or WebVTT

Tips & Best Practices
