Add it to the home screen
If you landed here because the network dropped, that is the point of the product: once a tool has loaded, it does not need me. Cached pages and encoders can still run. Drop a file you already have on the device.
What wifi-off actually means
First visit still needs the network — HTML, CSS, JavaScript, and whatever encoder that tool uses. Image tools are small. Video and audio pull about 30 MB of FFmpeg from this origin, once. AI tools pull a model from this origin, once. After that, the service worker can keep those bytes.
HTML pages themselves are not cached aggressively, because a cached homepage pointing at yesterday’s CSS is how deploys break. If you are fully disconnected and have never opened a tool, you may only see this page. If you have used a tool before, that tab or install may still have the encoder.
Install it
Add it to the home screen or install it as an app. That is a bookmark with a cache, not a native binary. Files still never leave the device.
Install the app
What still needs a network
- The first load of a page you have never visited
- The first load of FFmpeg, an image codec, or an AI model
- Analytics, if it runs — optional, not required for the tool
Turning wifi off midway through a conversion is fine. The file was never going to the network.
