Why convert VTT to YAML?

Converting VTT captions to YAML keeps the timings intact while matching the syntax your player, platform or browser actually parses. YAML (YAML Ain't Markup Language) earns its place here: human-friendly structured configuration with comments allowed. WebVTT is the subtitle format the HTML5 video element expects, adding styling, positioning and metadata cues on top of SRT's structure.

When VTT → YAML is the right move

  • Your player or platform expects YAML captions and ignores the VTT file.
  • You are embedding video on a web page, where caption format matters.
  • You want one subtitle format across a whole series instead of a mix.

Quality, size and what changes

Timings and caption text transfer exactly; only the syntax around them changes. Styling and positioning cues survive when YAML supports them and are dropped when it does not, and timestamp precision is preserved to the millisecond.

What you gain with YAML: Human-friendly structured configuration with comments allowed.

How it works

Drop your VTT file above and Morphio decodes it locally, then re-encodes it as YAML using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

VTT to YAML — frequently asked questions

How do I convert VTT to YAML without uploading the file?

Open the VTT to YAML page, drop your document on the drop zone and press convert. Morphio runs local parsers such as pdf.js that execute in your own tab, so the VTT data never leaves your device and no server ever receives a copy.

Does converting VTT to YAML lose quality?

Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting VTT to YAML only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the VTT to YAML converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Does converting VTT to YAML lose quality?

No. The content is remapped from VTT into YAML structurally, so nothing is re-compressed. Only features YAML has no way to express are left behind.

Can I convert several VTT files to YAML at once?

Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.

Are my VTT files uploaded anywhere?

No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
