About this tool
This creates a timed .srt subtitle file from a video or audio recording. SRT is the format almost everything accepts — YouTube, Vimeo, VLC, Premiere, Final Cut, DaVinci Resolve — which makes it the safe default when you are not sure what the destination needs.
How to generate SRT subtitles
- 1.Choose the video or audio file you want captions for.
- 2.Pick the spoken language, or leave it on auto-detect.
- 3.Press Run and wait for the job to finish.
- 4.Download the .srt file and load it alongside your video.
When people use it
Uploading to YouTube
Upload your own .srt instead of relying on the platform's automatic captions, so you control the wording and can fix names before anyone sees them.
Social video
Most people watch with the sound off. Captions are the difference between a video that works in a feed and one that gets scrolled past.
Accessibility
Captions are the baseline requirement for deaf and hard-of-hearing viewers, and a starting point for a compliance obligation you may already have.
Editing workflows
Bring the .srt into your editor as a caption track rather than typing every line by hand, then correct rather than author.
What it will not do
Worth knowing before you upload, rather than after.
- Timings follow the speech the model detects; expect to nudge a few of them in an editor for broadcast-grade work.
- There is no speaker labelling, so a multi-person conversation comes back as one voice.
- Punctuation and casing are the model's best guess, not an editor's decision.
- Captions are generated in the spoken language; this does not translate subtitles.
Questions
What is an SRT file?
A plain text file listing numbered caption blocks, each with a start time, an end time and the words spoken. It sits next to your video rather than being burned into the picture, so viewers can turn captions on and off.
Is the subtitle generator free?
Yes, free with no account and no watermark, for files up to 100MB.
Does this burn the subtitles into the video?
No. You get a separate .srt file, which is what YouTube and most editors want. The picture is untouched.
SRT or VTT — which do I need?
Use SRT for YouTube, editors and desktop players; it is the most widely accepted. Use VTT for HTML5 video on a web page. The only real difference is a header line and whether milliseconds use a comma or a dot.
Can I edit the captions afterwards?
Yes. An .srt is plain text — open it in any text editor, fix a name or a timing, and save. That is usually faster than re-running the job.
Do I need to extract the audio first?
No. Upload the video directly and the audio is pulled out automatically.
What happens to my file?
Your upload goes to private storage that is never public and never listed, and only the anonymous session that created the job can read it. The original file is deleted as soon as processing succeeds. The result stays available for about 90 minutes, and you can delete everything immediately with the Delete now button.
Do I need an account?
No. There is no sign-up, no email box and no watermark on anything you download. A short-lived anonymous session identifies your job so nobody else can fetch it, and that is the only thing stored about you.
