SRT vs VTT vs TXT: Which subtitle or transcript format should you use?
SRT vs VTT vs TXT: Which subtitle or transcript format should you use?
SRT = simple time‑coded subtitles; VTT = web‑friendly captions with styling and metadata; TXT = plain transcript without timing. For most creators who publish video online, VTT is the best default for web captions because it supports styling and modern players, SRT is the safest fallback for editors and broad compatibility, and TXT is the right choice when you only need the text for search, repurposing, or sharing. Use VTT for web-first deliveries, pick SRT when a platform or editor explicitly asks for it, and export TXT when you need a clean, editable transcript.
Why format choice matters
Choosing the right caption or transcript format changes how your audience experiences content, how easy it is to edit, and whether your files meet accessibility or platform requirements. A timed caption file (SRT or VTT) makes video accessible to deaf or hard‑of‑hearing viewers, improves search discoverability, and lets platforms display subtitles inline or burned into video. A plain TXT helps editors and writers repurpose content quickly but does not provide timing for on‑screen captions or meet most captioning compliance needs.
Format differences also affect styling, speaker labels, and metadata. VTT supports simple on‑screen styling and extra metadata cues that some web players read, while SRT focuses on timing and broad compatibility. TXT strips everything down to the words, which speeds translation and SEO work but loses timing and speaker cues unless you add them manually. Your delivery target, YouTube, social platforms, an LMS, an editor, should drive the choice more than personal preference.

| Format | Timing support | Styling / appearance | Metadata & speaker labels | Common use cases | Typical platform compatibility | Wisprs export availability | | ---------------------------------------------- | ------------------------------: | ---------------------------------------------------------- | -------------------------------------------------------------- | --------------------------------------------------- | --------------------------------------------------------------------------- | -------------------------- | | SRT | Yes, per cue start/end times | Minimal (text only; no CSS) | Basic sequence numbers; limited metadata | Broad compatibility for editors and legacy players | Accepted by YouTube, most NLEs, many players | Free: SRT export available | | VTT (WebVTT) | Yes, per cue plus position/line | Supports simple styling and positioning (WebVTT/CSS hints) | More flexible: comments, cues, chapter markers; better for web | Web captions, styled overlays, advanced web players | Preferred by many modern web players and browsers; also accepted by YouTube | Pro+: VTT export available | | TXT (plain transcript) | No, no timing by default | None | None by default (plain text) | Blog post repurposing, SEO, show notes, quick edits | Universally readable; not a caption format | Free: TXT export available |
Summary: choose VTT for web captions and any time you want styling or richer metadata; choose SRT when compatibility with editors, legacy players, or platforms matters; choose TXT when you only need the text for repurposing or proofreading.
Detailed breakdown: SRT, VTT, and TXT
SRT, what it is, pros and cons, and when to choose it
SRT (SubRip Subtitle) is a plain text format that contains numbered subtitle cues with start and end timestamps and the subtitle text. Its simplicity makes it the most widely supported caption file for video editors, broadcasters, and many platforms. Editors appreciate SRT because it translates easily into timeline subtitle tracks and most NLEs import it without fuss.
SRT pros and cons are straightforward. It works virtually everywhere that accepts timed captions, keeps files small, and is human‑readable. The tradeoffs are a lack of styling control and limited metadata support; you cannot reliably position text with CSS-like hints and speaker labels are not standardized in the SRT spec. Use SRT when you need maximum compatibility with editors, when a client or platform explicitly requests SRT, or when you want a compact timed caption file without styling overhead.
Common platforms that accept SRT (examples)
- YouTube (upload captions or use as fallback)
- Most non‑linear editors (Premiere, Final Cut, DaVinci Resolve)
- Many subtitle importers for broadcast and video hosting
VTT (WebVTT), what it is, pros and cons, and when to choose it
WebVTT (VTT) is a timed text format created for the web that adds optional styling, positioning hints, and richer metadata inside cues. VTT files can include simple styling tokens and cue settings that modern browsers and HTML5 players can interpret, allowing captions to appear in specific screen positions and with minimal markup control. That makes VTT preferable when you need captions to match a responsive website layout or to preserve emphasis and speaker labeling for viewers.
VTT's advantages include web compatibility, styling hooks, and expanded metadata (comments, regions, chapters). The downsides are that some legacy players ignore VTT styling or interpret cue settings inconsistently, and not every publishing tool exposes VTT features. Use VTT for web‑first publishing, when you want on‑screen positioning, or when your playback environment supports WebVTT.
Common platforms that accept VTT (examples)
- Modern HTML5 players and web platforms
- Browser‑native caption rendering in web pages
- Many video hosting platforms that prefer VTT for web playback
TXT (plain transcript), what it is, pros and cons, and when to choose it
A TXT transcript is an untimed, plain text file that contains the spoken words with optional speaker labels or paragraph breaks. It is the fastest file for repurposing content into show notes, blog articles, or social copy. Since TXT lacks timing, it does not work as a caption file to display text in sync with video; instead, it’s for editorial and SEO use.
TXT files are universally readable and editable in any text editor. Their limitations are obvious: they don’t meet captioning or accessibility requirements for timed captions, and they require additional work if you later need to convert words into timed cues. Choose TXT when your priority is text editing, translation, or creating derivative content rather than delivering captions to a player.
Common platforms and uses for TXT (examples)
- Blog CMSs and content repurposing workflows
- Translation and copyediting workflows
- Internal show notes, email summaries, and SEO content
How to export SRT, VTT, and TXT from Wisprs
Wisprs provides direct export options and a simple workflow to get the format you need for publishing or editing. The exact exports available depend on your plan: Free accounts can export TXT and SRT, while Pro and higher plans add VTT, DOCX, and JSON outputs. Follow these basic steps to export from Wisprs.
Step-by-step: export a caption or transcript file from Wisprs
- Upload or record your audio or video in the Wisprs workspace and wait for the transcription job to complete. (Paid plans can use ElevenLabs Scribe for diarization; free tier uses a self‑hosted Whisper‑based model.)
- Open the transcription editor and review or correct any errors. Add speaker labels if required; diarization is available on paid plans but may need manual correction in noisy audio.
- Choose Export in the top-right menu and select the desired format (SRT or TXT on Free; add VTT, DOCX, or JSON on Pro+).
- If exporting VTT, set cue length and line breaks in the export dialog so timing matches your desired reading speed.
- Download the file and test it in your player or upload it to your platform.
If you want a free hands-on test, start with Wisprs’ free audio tool or sign up to try a full upload: see /tools/free-audio-to-text and the product export details at /product/transcription#exports.
How to convert between SRT, VTT, and TXT
Converting formats is common when a platform asks for a specific file type or when editors need different formats for different stages. Conversions can preserve timing but might lose styling or speaker metadata depending on the direction.
Quick conversion options
- Simple rename/format change: Some players accept an .srt file renamed to .vtt, but this is unreliable because VTT has different cue formatting and optional headers; always validate after renaming.
- Command-line conversion: Use ffmpeg or subtitle toolchains to convert faithfully. Example ffmpeg command to convert SRT to VTT: ffmpeg -i input.srt output.vtt: this preserves cue timing and outputs WebVTT format.
- Wisprs exports: If you have Pro+ access, export directly as VTT to avoid reformatting. Free users can export SRT and convert externally if needed.
When converting, always open the resulting file to check cue timing, line breaks, and any lost metadata. Converting TXT to a timed format requires automated tooling with speech alignment or manual cue insertion; Wisprs can produce timed files natively, which is faster and less error‑prone than starting from TXT.
Examples and decision scenarios
YouTube upload: best format and how to include captions If you upload a finished video to YouTube, SRT is a safe choice because YouTube accepts SRT and VTT. Use SRT when you want a quick timed upload that editors can import. Use VTT if you rely on web styling later or want more flexible positioning for embedded players. After exporting from Wisprs, upload the file in YouTube Studio under Subtitles → Add. For step details on adding captions, see /blog/how-to-add-captions-to-youtube.
Social short (Instagram, TikTok) captions: burned‑in vs. file import Short social platforms mostly prefer burned‑in captions or platform-native sticker captions rather than sidecar files. Use TXT or SRT to generate the caption text and then create burned‑in captions in your editor or a caption‑burning tool. If the platform supports sidecar import during ad placements or advanced workflows, SRT will usually work; for web embeds, prefer VTT.
Plain transcript for blog repurposing When creating a blog post or article from audio, export TXT for clean copy. Use Wisprs’ TXT or DOCX exports (DOCX on Pro+) to preserve paragraph breaks and speaker annotations for faster editing. For SEO, paste the cleaned transcript into your CMS and add headings, links, and summaries.
Accessibility and legal requirements: when timed captions are required For accessibility or compliance (ADA, accessibility guidelines, or institutional policies), timed captions are generally required when delivering video content with speech. Use SRT or VTT to provide readable, synchronized text. VTT adds extra control for web presentation, which can help meet on‑page accessibility needs, while SRT offers broad compatibility for platform submissions.
Pitfalls and best practices
Watch the timing, chunk length, and cue readability to avoid bad captions that are technically correct but unusable. Too many words per cue or cues that appear too briefly make captions hard to read; aim for 1–2 lines per cue and 1.5–3.5 seconds per short cue where possible. Always preview captions in the target player and check line breaks and reading speed.
Key practical best practices
- Keep cues short and readable; break long sentences into two cues at natural pauses.
- Set a readable on‑screen duration for each cue; viewers need time to scan text.
- Test files in the exact player or platform before final delivery; behavior differs between players.
How Wisprs handles exports, diarization, and plan differences
Wisprs supports the common export formats you need and maps them to plan entitlements: Free accounts can export TXT and SRT; Pro and higher tiers add VTT, DOCX, and JSON exports. For transcription engines, Wisprs routes jobs based on plan and file size: the free tier uses self‑hosted Whisper‑based models, while Pro/Studio/Agency/Enterprise routes use ElevenLabs Scribe for paid STT with native diarization. The router may use OpenAI Whisper as a fallback in special cases.
Speaker identification (diarization) is available via ElevenLabs Scribe on paid plans, but automatic labels may need manual correction in noisy or overlapping speech. Wisprs also offers language auto‑detection across many languages, batch upload on higher tiers, and real‑time WebSocket transcription where applicable. For the most current export details and how to change formats inside the product, check /product/transcription#exports and consider account options at /pricing before you decide which export you need.
How to test and validate your caption files quickly
Always validate exports before final delivery. A quick validation workflow helps catch timing errors, cue overflow, and unsupported styling markers.
Quick validation steps
- Open the exported file in a plain text editor to check cue formatting and timestamps.
- Load the file into your target player or upload it to a staging instance of the platform to preview live behavior.
- Confirm reading speed and line breaks by watching segments with fast dialogue.
- If you used automatic speaker labels, scan for obvious misattributions and fix them in the editor.
Conversion and tooling references (quick list)
If you need third‑party tools or quick commands to convert or manipulate files, these commonly used options work reliably for most creators:
- ffmpeg: command-line multimedia tool that can convert SRT to VTT and rewrap subtitles while preserving timing.
- Subtitle Edit or Aegisub: desktop subtitle editors that let you visually re‑time, style, and export in multiple formats.
- Wisprs exports: export directly from the Wisprs editor in the format you need to avoid conversion steps when possible.
