Free Online Subtitle Editor
Open an SRT or VTT file, fix the words and timing against your video, and download it again. Nothing is uploaded.
Fix Subtitles Without an Editing App
Auto-generated subtitles are almost right: a misheard name here, a line that shows up half a second late there. Open the file, play your video next to it, and fix each line in place.
Shift every line at once when the whole file is out of sync, fix overlapping lines in one click, and spot lines that flash by too fast to read. Then download SRT for YouTube and editors, or VTT for the web.
Want Captions Burned Into 50 Videos at Once?
Skip the subtitle files: BatchEdits transcribes, styles and burns captions into every video, removes silences and crops to 9:16, for up to 50 videos in one go.

Got Questions? We've Got Answers.
Is this subtitle editor free?
Yes, completely, with no signup and no limits. It runs in your browser, so your subtitle file and video never leave your device.
Which subtitle formats can I edit?
SRT and WebVTT (.vtt). You can open either and download either, so it also converts SRT to VTT and back.
How do I fix subtitles that are out of sync?
Use Shift all: enter the number of seconds and press Earlier or Later to move every line at once. For single lines, play your video and use the clock buttons to set a line's start or end to the current moment.
Can I preview subtitles on my video?
Yes. Add your video and the current line shows on top of it while it plays. Click any line to jump to it. The video stays on your device.
What do the warnings mean?
Overlaps next means the line ends after the next one starts; Fix overlaps corrects them all. Too fast to read means more than about 20 characters a second. Too long means more than two lines of 42 characters.
I don't have a subtitle file yet. What do I do?
Make one from your video with the free video transcript generator, which downloads an SRT. Or let BatchEdits caption up to 50 videos at once and burn the captions in.
How do I edit an SRT file online for free?
Open it in the BatchEdits free subtitle editor: fix the text and times line by line, preview against your video, shift all timings, fix overlaps, then download SRT or VTT. It runs in your browser with no signup.
How do I convert SRT to VTT?
Open the SRT in the BatchEdits free subtitle editor and download it as VTT, or the other way around.
How do I fix subtitles that are out of sync?
Shift every line earlier or later by a set number of seconds, then fine-tune single lines against the video. The BatchEdits subtitle editor does both in the browser.
