HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your SRT file
Drag and drop a .srt file or select it from your device. Its text encoding is detected automatically.
02
Convert to VTT
Keep VTT as the output format and start. Bold, italic and underline are kept, and common SRT formatting mistakes are repaired along the way.
03
Download the VTT
Download the UTF-8 .vtt file and add it to your video player or web page as a caption track.
SRT
SRT (SubRip) is the most common subtitle format: a plain-text list of numbered subtitles, each with a start and end time and one or more lines of text. Video editors, media players, TVs and YouTube read it, and it supports only simple tags such as bold, italic, underline and font color.
VTT
WebVTT (.vtt) is the W3C caption format behind the HTML5 <track> element. Browsers show it with a <video>, and web video players, YouTube and many course platforms accept it. Each cue holds its timing and text, with optional simple styling and an on-screen position.
FILE FORMATS
SOURCE
SubRip Text began with the SubRip ripping tool in the early 2000s. Each subtitle is a number, a start and end time with a comma before the milliseconds, and one or more lines of text. Premiere Pro, DaVinci Resolve, VLC, smart TVs, YouTube, Facebook and LinkedIn all accept SRT.
TARGET
Web Video Text Tracks is the W3C caption format for the <track> element in HTML5 video. Each cue has a start and end time with a dot before the milliseconds, and optional settings place the text on screen. Video platforms, lecture recordings and meeting tools such as Zoom and Teams export captions as VTT.
| Feature | SRT | VTT |
|---|---|---|
| Developed by | SubRip (community) | W3C |
| File extension | .srt | .vtt |
| Styling | Basic bold, italic, underline | Bold, italic, classes via CSS |
| Positioning | No (some players read {\an8}) | Yes, cue settings |
| Best for | Editors, TVs, uploads | Web and HTML5 players |
| Works in | Almost every player and site | Browsers, web players |
USE CASES
Practical workflows where SRT to VTT conversion is useful.
Add captions to an HTML5 video
Web developers can attach the .vtt to a <video> element as a <track>. Browsers read WebVTT captions there, not SRT.
Load captions into a web video player
Players such as Video.js and Plyr load WebVTT caption tracks. Convert the SRT your editor exported and point the player at the .vtt.
Package subtitles for HLS streaming
HLS streams carry subtitles as WebVTT. Convert the SRT delivered with a film or series before packaging it with your streaming tools.
Caption lessons on a course platform
Course platforms that ask for WebVTT captions get a file with the same text and timings as the SRT from your captioning service.
Fix garbled accents in an old SRT
SRTs saved in old Windows or Asian code pages often show broken letters on the web. The conversion detects the encoding and writes UTF-8, so accents, £ and € signs and non-Latin text display correctly.
Repair a badly formed SRT
Hand-edited SRTs with missing blank lines or numbers, dots instead of commas or cues out of order are repaired while converting, so the VTT plays cleanly.
Keep top-of-screen subtitles in place
Subtitles marked {\an8} so they don't cover on-screen text stay at the top of the screen in the WebVTT file.
Clean up SRTs made from ASS scripts
SRTs exported from fansub scripts often contain \N and \h codes. In the VTT they become real line breaks and hard spaces instead of showing as text.
Publish captions in several languages
Translators often deliver one SRT per language. Add them all to one job to get a WebVTT caption track for each language.
Convert a mislabeled subtitle download
Some subtitle sites serve MicroDVD files with an .srt name, and the converter recognizes the real format and converts it. A MicroDVD file that does not state its frame rate is timed at 23.976 fps, so one made for 25 fps video drifts out of sync.
SUPPORTED FILES
SRT files, even badly formatted ones, are supported.
From editors, downloads and rips.
Missing numbers, dots instead of commas and joined files are repaired.
Keep their position in the VTT.
Recognized and converted.
Upload several SRTs and download the VTT files as a ZIP.
TROUBLESHOOTING
Most issues come from features one format has and the other doesn't.
01
WebVTT has no inline color without a separate stylesheet, so <font> colors are removed.
02
MicroDVD files without a stated frame rate are timed at 23.976 fps. A file made for 25 fps video will drift.
03
Plain text without timings can't be converted.
04
A single subtitle with more than 1,000 lines is treated as damaged.
05
The encoding is detected automatically. A very short file whose only accented letters fit several code pages can be misread; re-save it as UTF-8 and convert again.
06
Video files, picture-based subtitles and other binary files renamed as subtitles are refused with a message saying what they are.
