About this tool
WebVTT is what browsers use, but desktop players, television media players, and most video editing software expect SubRip .srt files. This tool converts WebVTT subtitles to SRT.
The WEBVTT header, NOTE comments, STYLE blocks, and REGION definitions are removed, timestamps are rewritten with a comma before the milliseconds, and cues are renumbered from one.
Supported formats and limits
- Input
- .vtt
- Output
- .srt (application/x-subrip)
- Output name
- The original name with the new extension, for example data.vtt becomes data.srt.
- File size limit
- 25 MB
- Processing
- In your browser. The file is not uploaded.

How to use it
- Choose a .vtt file, or switch to Paste text and paste the subtitles directly.
- Select Convert, then download the .srt file.
Limitations
- Cue settings such as line, position, size, and align are dropped, because SRT has nowhere to put them.
- STYLE blocks and any CSS they contain are removed. SRT has no styling model.
- Cue identifiers are replaced with sequential numbers.
- WebVTT allows timestamps without an hours component; these are expanded to the full hours:minutes:seconds form SRT requires.
- Inline tags such as <v Speaker> voice spans are passed through as written and may show as literal text in some players.
Common problems
The file was refused before anything started.
VTT to SRT converter checks the extension before it reads a byte, and it accepts .vtt. Browsers report file types inconsistently enough that the extension is what decides.
Rename the file if the extension is simply wrong, or convert it to one of those first. A file whose extension does not match its contents is refused for the same reason, and that one needs converting rather than renaming.
It said the file was too large.
The limit here is 25 MB. It is not a policy but a measurement: everything runs on your own device, and past that size a phone runs out of memory rather than finishing slowly.
Split the file, reduce it before converting, or use a desktop program for that one. A machine with more memory will manage more, but the limit does not know which machine it is on.
I selected several files and only one converted.
This tool takes one file at a time. Doing several at once would multiply the memory in use, which is the thing most likely to fail on a phone.
Convert them one after another. Nothing is kept between them, so there is no state to reset.
The tab reloaded itself part-way through.
The browser ran out of memory and restarted the page. At sizes approaching 25 MB this is the failure a phone hits first, and it looks like a crash rather than an error.
Try a smaller file, close other tabs, or run it on a computer. Nothing was uploaded or lost — the original file is untouched on your device.
The result opened in the wrong program.
The output is a .srt file, and your system opens that extension with whatever it was told to. Nothing about the conversion decides it.
Open it from inside the program you want, or change the default for .srt in your system settings. The file itself is correct.
Frequently asked questions
- Is my file uploaded?
- No. The conversion runs entirely in your browser. The file never leaves your device and no request carrying its contents is made.
- Why was my file rejected?
- A WebVTT file must begin with the word WEBVTT. If it does not, it is not a valid WebVTT file, and it is more likely an SRT file with the wrong extension.
- Do I lose anything?
- Positioning, styling, and cue identifiers, none of which SRT can represent. The text and the timings are preserved exactly.
- Can I convert back?
- Yes, with the SRT to VTT tool, but the settings and styling removed here will not come back.
- Do I need to install anything or create an account to use VTT to SRT converter?
- No, to all of it. VTT to SRT converter runs inside the browser you already have, with no sign-up, no download, no watermark on the result, and no cap on how many files you convert. There is nothing to uninstall afterwards either, because nothing was installed.
- Does VTT to SRT converter work offline?
- Once the page has loaded, yes. The conversion runs on your device, so it needs no connection to do the work. The first visit fetches the page and the code that does the converting; after that a lost connection stops nothing, and a converted file appears exactly as it would online.
- How large a file can VTT to SRT converter handle?
- The limit is 25 MB. It is a deliberate one rather than a technical ceiling: the real constraint is memory, and a file that decodes to more than the device can hold fails in a way that is hard to explain. Phones run out well before laptops do, which is why the limit is set where it is.
- Can I convert several files at once with VTT to SRT converter?
- Not here: this tool takes one file at a time, because what it does depends on choices you make about that particular file. Convert them one after another, or look at the batch converters in the same category, which are built for a folder at a time.
