What is an SRT online editor?
SRT is a timed subtitle format used by players and editors. This free browser tool lets you open common subtitle or text files, edit cue text and timing in a large workspace, then export clean SRT.
Upload accepts text, SRT, VTT, and ASS. Paste tab is for plain transcripts (estimated timing). For timestamps that match real speech, upload audio to SayToWords.
How to edit SRT online
- Upload a .txt / .srt / .vtt / .ass file, or open the Paste tab for plain text
- Cues appear in the right workspace — edit start, end, and text
- Use shift tools on the left if needed
- Download SRT — free, no signup
Estimated timing from plain text is a starting point. Sync cues to your video in the table, or generate subtitles from audio for speech-accurate timestamps.
