02 The promise

Your videos never leave your device

No upload endpoint

Files are read straight into the page with the File API. There is literally no server to send them to.

Real browser processing

Canvas, MediaRecorder, WebAudio and WebCodecs do the work — with heavy lifting in Web Workers.

See savings first

Compression and resize tools show before/after size and estimated savings before you download.

03 How it works

From drop to download — nothing in between travels

1

Drop your video

The File API hands the page a local reference. No bytes cross the network.

2

Decode locally

The browser decodes frames into a video element and Canvas.

3

Process on-device

Canvas + MediaRecorder + WebAudio re-encode or extract, in a worker where possible.

4

Download result

The finished file is assembled in memory and saved from the tab.

05 Questions

No. VideoDock has no upload endpoint. Files are opened locally and every operation runs in your browser tab.

Anything your browser can decode — typically MP4, WebM, MOV and more. Re-encoded output is WebM; the FFmpeg build adds MP4.

The core tools are free. Pro and Business on the pricing page are upgrade-ready placeholders.

Once the page has loaded, most tools keep working without a connection, because all processing is local.
