Turning a RTF file into VTT changes what you can do with the document: read it, edit it, sign it, print it or hand it to a system that insists on one format. VTT (WebVTT subtitle) earns its place here: native browser captions with styling and positioning control. RTF is Microsoft's plain-text-with-formatting exchange format from 1987. WordPad, legal templates and older systems still emit it and nearly every word processor can open it.

Text and structure move across from RTF to VTT; how faithfully the layout follows depends on how much layout VTT can express. Fixed-layout targets keep pagination exactly as it looks, while text-oriented targets keep the words and headings and let the reader reflow them. Fonts not embedded in the source are substituted.
What you gain with VTT: Native browser captions with styling and positioning control.
Drop your RTF file above and Morphio decodes it locally, then re-encodes it as VTT 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.
Open the RTF to VTT 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 RTF data never leaves your device and no server ever receives a copy.
Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting RTF to VTT only rewrites the container and encoding you asked for — the source file on your disk is never modified.
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.
No. The content is remapped from RTF into VTT structurally, so nothing is re-compressed. Only features VTT has no way to express are left behind.
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.
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.
