VTT to HTM — Private In-Browser Converter

Why convert VTT to HTM?

Converting VTT captions to HTM keeps the timings intact while matching the syntax your player, platform or browser actually parses. HTM (HTML document) earns its place here: universally viewable structured text with live links. WebVTT is the subtitle format the HTML5 video element expects, adding styling, positioning and metadata cues on top of SRT's structure.

When VTT → HTM is the right move

Your player or platform expects HTM 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 HTM supports them and are dropped when it does not, and timestamp precision is preserved to the millisecond.

What you gain with HTM: Universally viewable structured text with live links.

How it works

Drop your VTT file above and Morphio decodes it locally, then re-encodes it as HTM using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Free supports batches of 5 files; Pro supports batches of 250, subject to your device's memory. See exactly how in-browser conversion works.

VTT to HTM — frequently asked questions

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

Open the VTT to HTM 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 HTM lose quality?

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

Is the VTT to HTM 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 HTM lose quality?

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

Can I convert several VTT files to HTM at once?

Yes — Free supports batches of 5 files and 10 conversions per day; Pro supports batches of 250 with no daily conversion cap. Your device's memory can impose a lower practical limit. Only usage counts reach the server, never files.

Are my VTT files uploaded anywhere?

No. The conversion runs entirely inside your browser, so the file never leaves your device. The page and the required decoder must load first; free usage-limit checks may require a connection.
