Free Browser Subtitle Editor
Open an SRT file as editable cue rows, change text and timing, add or remove captions, then download a renumbered SRT.
Nothing is autosaved—download before closing the tab.
The editor stores working data only in this tab's memory. It does not upload, autosave, or log subtitle content.

What the browser changes
Cue times are edited in decimal seconds for precision. Export rejects non-numeric or reversed ranges, sorts cues by start time, and writes standard SRT timestamps.
- Correct names before importing captions to Premiere.
- Nudge individual cue boundaries after a picture edit.
- Remove unwanted captions from an automated transcript.
- This is a cue editor, not a waveform or video preview.
- Changes are lost when the tab closes unless you download the SRT.
- Overlapping cues are allowed and must be reviewed manually.
Quick answers

No. Download the SRT before closing or reloading the tab.
Can I preview video?
