Subtitle Editor
Create and edit SRT subtitles with start/end timings, live preview against your video and .srt export.
Parse a file to start editing.
Parses SRT (comma or dot milliseconds), lets you edit timings/text inline, bulk-shift for sync fixes, then re-serialises a clean 1-based SRT. Your subtitle file never leaves the browser.
About Subtitle Editor
Create and edit SRT subtitles with start/end timings, live preview against your video and .srt export.
Subtitle Editor is a browser based workspace for building and refining timed captions without installing anything. Add each line, set exact start and end times, and watch the live preview over your video to check that every cue lands on the right word. The list keeps entries in order with clear timings, so retiming a late caption or splitting a long one takes seconds. Paste an existing caption file to correct spelling and durations, or start from an empty track for a new recording. When everything looks right, export the finished track and upload it with your video. Subtitle Editor works on desktop and mobile, keeps your footage on your device, and is free for creators, students and trainers who want accessible video.

Frequently Asked Questions
Can I preview subtitles against my video while editing?
Yes. The preview panel plays your video next to the caption list, so every line appears in real time as the file runs. Scrub back over a section, adjust a start or end time, and play it again immediately to confirm the text matches the speech. Because the preview is local, changes show up instantly without exporting just to check your timing.
Is Subtitle Editor free to use?
Yes. Subtitle Editor is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Subtitle Editor runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Subtitle Editor work on mobile?
