Local-only video conversion requires running the separate vertd daemon alongside the main app.

In plain English

VERT is a file conversion utility that runs in the browser. The README describes it as a tool that uses WebAssembly to convert files on the user's own device rather than sending them off to a cloud service. There is a live hosted version at vert.sh, but the same code can be run locally. The project is written in Svelte and TypeScript. The README lists the main features. Conversion happens directly on the device using WebAssembly, with no file or file size limits. The tool handles images, audio, documents, and video, and the project claims support for more than 250 file formats. There are settings for each conversion, and the interface is described as user-friendly. There is one caveat about video. Non-local video conversion is offered through the official hosted instance, because video conversion is heavier than the browser can comfortably handle. For people who want to keep everything on their own machine, the README points at a separate companion project called vertd, which is the daemon that does the video work and is described as easy to self-host. The README links to a small set of docs: an FAQ, a getting-started guide, instructions for running with Docker, and a video-conversion page. The project is licensed under the AGPL-3.0 license. Screenshots of the upload page and the conversion page are included.
