Editing features
A practical subtitle editor for common fixes
This tool focuses on the subtitle editing jobs creators do before publishing, reviewing, or moving captions into another workflow.
Edit SRT and VTT cues
Work with subtitle rows instead of hunting through raw text blocks.

Shift every cue forward or backward when captions are early or late.
Validate subtitle files
Catch malformed timestamps, empty cues, reversed timing, and overlaps before export.
Clean export formats
Download edited captions as SRT, VTT, TXT transcript text, or a simple ASS subtitle file.
Format notes
Edit subtitles without changing your workflow
Use the editor for lightweight subtitle corrections, then export the format your video platform, player, or editing app expects.
SRT editing
SRT is widely accepted by social platforms, video editors, and review workflows.
VTT editing
VTT works well for web video, HTML5 players, course platforms, and documentation sites.
TXT and ASS export
TXT gives readable transcript text, while ASS provides a simple styled subtitle file for compatible editors.
