.srt. Use SRT to VTT. - Your video editor rejects the file → it’s probably WebVTT. Use VTT to SRT.
- Subtitles appear too early or too late → Shift subtitle timing.
- You want a readable transcript → Remove timestamps.

[Music]and markup → Clean up AI subtitles.
Frequently asked questions
Are these tools really free?
Yes. There is no account, no usage quota and no watermark. The site is supported by advertising, which is why you may see ads on the page.
Do you store my subtitle files?
No. Files are read directly by your browser and processed in memory. Nothing is transmitted to a server, and nothing is written to storage. Closing the tab discards everything.
Is there a file size limit?
No server-side limit, because nothing is uploaded. In practice the limit is your browser’s available memory — files of several megabytes process instantly.
Which formats are supported?
SubRip (
.srt) and WebVTT (.vtt) are fully supported, plus most .sbv-style files that use the HH:MM:SS,mmm --> HH:MM:SS,mmm arrow syntax.Can I use these tools offline?
Yes. Once the page has loaded, the conversion logic runs locally, so it keeps working if you lose your connection.
