Subtitle Formats: SRT, VTT, and TXT Explained
DownSub focuses on three practical outputs: timed subtitle files for playback and editing, plus a clean text transcript for reading and research.
What is SRT?
SRT, short for SubRip Subtitle, is one of the most widely supported subtitle formats. It stores caption order, start/end times, and text — the safe pick for editors, desktop players, course platforms, and broad compatibility.
What is VTT?
VTT, or WebVTT, is built for web video. It works well with HTML5 video tracks and web-friendly cue metadata — the right pick when captions will live on a site, product, lesson page, or browser-based player.
What is TXT?
TXT is a plain transcript. It drops most timing and formatting so the text is easier to scan, quote with permission, search, annotate, or summarize — the right pick when readability beats playback timing.

| Question | SRT | VTT | TXT |
|---|---|---|---|
| Best for | Editing, media players, course uploads | Web players and HTML5 track elements | Reading, notes, search, summaries |
| Timing | Yes | Yes | Usually removed |
| Typical users | Editors, teachers, accessibility reviewers | Developers, publishers, product teams | Students, researchers, writers |
| File style | Numbered caption blocks | Cue-based web caption format | Plain text transcript |
Which format should you actually use?
- Use SRT when you need subtitles in a video editor, player, LMS, or upload workflow.
- Use VTT when the captions will live in a web video player or HTML5 track element.
- Use TXT when you need a readable transcript for study, notes, research, or planning.
- Review auto-generated captions before publishing — they can miss names, punctuation, and technical terms.
Responsible format use
File format doesn't change copyright responsibility. Use captions only for videos you own, have permission to use, or where the law and platform terms allow it.
Choosing the right subtitle file starts with a simple subtitle format comparison: SRT, VTT, and TXT all carry the same captions, but each one is built for a different job. This subtitle format comparison walks through where SRT, VTT, and TXT are strongest so you know exactly which one to pick after your download finishes.
Subtitle Format Comparison: SRT vs VTT vs TXT
Every subtitle format comparison comes down to three questions: where will the file be used, does it need timestamps, and who else needs to open it. SRT and VTT are both timed formats, so playback software can sync each line to the video. TXT drops the timing entirely and keeps only the words, which makes it easier to read and search but useless for actual caption playback.
SRT: The Safest Default for Editors and Players
SRT (SubRip) is the most widely supported subtitle format in this comparison. Nearly every video editor, media player, and course upload system accepts SRT without conversion, which is why it’s usually the safest first choice when you’re not sure what a tool expects.
VTT: Built for Web Video and HTML5 Captions
WebVTT (VTT) is the format web browsers and HTML5 <track> elements expect natively. If you’re publishing captions on a website or a self-hosted video player, VTT saves you a conversion step that SRT would otherwise require.
TXT: Best for Reading, Research, and Search
TXT strips out timestamps and cue numbers, leaving a plain transcript that’s fast to read, easy to search, and simple to paste into notes. It’s the right pick for students, researchers, and language learners who care about the words, not when each line appears on screen.
- Editing or uploading to a course platform: choose SRT.
- Publishing captions on your own website: choose VTT.
- Studying, searching, or quoting a transcript: choose TXT.

Subtitle format FAQ
SRT for editing software and broad player support, VTT for a web video player, and TXT when you just want readable transcript text for notes or research.
You can download any available caption track as SRT, VTT, or TXT. If you move a file between tools afterward, double-check the timing and cue order still line up.
No — TXT drops timestamps on purpose so the transcript reads cleanly. Use SRT or VTT when timing matters.
