What MediaVault does
MediaVault processes video entirely on-device. You can compress a large file for email, convert formats, generate a transcript, and make quick edits without a single byte leaving your machine.
Most free video tools work by uploading your footage to someone else's server and stamping a watermark on the result. MediaVault removes both problems by doing the work locally.
Who should use it
Creators, editors, and anyone handling footage that shouldn't be uploaded — client work, internal recordings, interviews, or anything under an NDA.
Who built it
MediaVault is built and operated by EchoVerse, and shares its offline, nothing-uploaded approach with PDF Vault — also ours.
When it's not the right fit
MediaVault runs entirely in your browser, and that architecture sets its ceiling. Processing is bounded by your device's memory and CPU, so very long files or large batches will be slower than desktop software with native access to your hardware.
That is the deliberate trade: nothing is uploaded, so nothing can leak, but you also cannot hand the work to a server farm and close your laptop.
It is also a utility rather than an editing suite. Timeline editing, colour grading and multi-track audio are a different category of tool.
