Online Subtitle Editor for SRT & VTT
Edit subtitle text and timestamps, find and replace words, and add or remove captions. Export a reviewed SRT or VTT file.
About Subtitle Editor
Use the subtitle editor to proofread captions before publishing. Correct a name across multiple cues, adjust an individual start or end time, or remove a mistaken caption. You can open SRT, VTT, ASS/SSA or SBV and export plain SRT or VTT captions.
What to expect
- Times are edited in seconds, with millisecond precision. Invalid times or empty captions block export.
- Find and replace uses literal, case-sensitive text. It does not run regular expressions or rewrite other words.
- Overlapping captions are preserved; check them in your player. Styles and positioning are not included in edited exports.
- Edits stay in this tab. Download your result before leaving; there is no automatic cloud save.

Frequently asked questions
Can I edit a name everywhere?
Yes. Find and replace applies a literal, case-sensitive replacement to all subtitle text, including captions on other pages. Preview the output before downloading.
Are edits saved automatically?

Does this edit the video itself?
