SRT vs VTT vs TXT: Choose the Right Subtitle Format

Published on November 12, 2026

SRT, VTT and TXT can contain the same words, but only two of them are true timed-subtitle formats. The best choice depends on where the file will be used after download.

The decision in one minute

• Pick SRT for editors, desktop players and the safest general compatibility.
• Pick VTT for HTML5 video and browser-native captions.
• Pick TXT for reading, searching or notes when synchronized playback is unnecessary.

What an SRT file stores

SRT separates captions into numbered blocks. Each block contains a start time, an end time and one or more text lines:

text 1 00:00:04,200 --> 00:00:07,100 This line appears for 2.9 seconds.

The comma in the milliseconds field is part of SRT syntax. Most video editors and media players recognize this structure immediately, which makes SRT the dependable default.

What makes WebVTT different

A VTT file starts with WEBVTT, uses a period for milliseconds and can support web-oriented cue settings:

```text WEBVTT

00:00:04.200 --> 00:00:07.100 This cue belongs in a web player. ```

VTT is the natural match for an HTML <track> element. It can also carry cue positioning and metadata that plain SRT does not standardize.

What TXT leaves out

TXT removes the subtitle container and presents the caption words as ordinary text. That is useful for proofreading or notes, but a player cannot know when to display each line. Renaming a .txt file to .srt will not add timing.

Compatibility comparison

Can you convert between them?

SRT and VTT can be converted reliably because both include time ranges. Check the milliseconds separator, remove or add the WEBVTT header, and preserve blank lines between cues.

Converting TXT is different. Without source timestamps, a converter must guess the timing or align the text against audio. That is subtitle generation, not a simple format change.

Editing without breaking the file

Keep cue order chronological, use valid timecode punctuation and leave a blank line between cues. Avoid overlapping time ranges unless the target player supports them. Our SRT editing guide covers safe changes in detail.

FAQ

Is VTT better quality than SRT?

No. Caption accuracy comes from the underlying track. The formats mainly differ in syntax and supported presentation features.

Which format should I upload to YouTube?

SRT is usually the simplest choice. YouTube accepts several caption formats, but SRT is easy to inspect and broadly reusable.

Can TXT be used as subtitles?

Not directly. A subtitle player needs timed cues, which ordinary TXT does not contain.

What this guide uniquely answers

Choose a subtitle export by what must remain after download: timing, browser features, or words only.

Worked example

A course owner needs captions in an editor, on an HTML5 lesson page, and in study notes. Keep SRT as the interchange master, create VTT for the web player, and generate TXT only for reading.

Expected result: Three purpose-specific files without discarding the timed master.

If it fails: If a platform rejects the file, check its supported format rather than renaming the extension.

Verification checklist

• Destination identified
• Timed master retained
• Timestamp punctuation validated
• Final file tested in its target
