Cast your own files from the browser

Choose the connection your devices support

On a computer, use Google Chrome with a Google Cast TV or receiver on the same Wi-Fi. Android Chrome can use the website’s TV chooser and an automatically opened receiver. If Chrome cannot find the TV, an Android phone can instead mirror this player through its own Cast quick setting.

On iPhone or iPad, use the in-page player with Apple’s Screen Mirroring and an Apple TV or AirPlay-compatible television. A Chromecast-only receiver cannot use that iPhone route. A TV being “smart” does not establish Google Cast or AirPlay support. Google’s Web Sender platform list and Apple’s mirroring instructions describe these different systems.

Select one file and start playback

1. Open the player and drop a file into it, or choose a file from your device.
2. Wait for inspection and preparation to finish. A thumbnail can appear, but it is not a local video preview.
3. On desktop or Android direct Cast, press Cast and choose your TV in Chrome’s picker. On a phone mirroring route, open the local player, choose the TV through the phone’s system controls, return and press Play.
4. Use the playback controls to pause, seek, mute or change volume. PDF controls move between pages.

The homepage holds one current file. Selecting another replaces that selection. Closing or reloading the browser loses it, so keep the page open during your screening.

Choose sound and subtitles

Open the gear-shaped Settings button to choose an available audio track or preparation quality. Open Subtitles to select an embedded text track or use Add subtitle file. Selectable captions can change during playback, and Text size changes their display size.

A file extension alone cannot tell you whether every track can play. MKV and MP4 are containers; their video, sound and subtitle codecs may need different preparation. Start with the supported file formats guide if preparation fails, or the subtitle guide for caption choices and limits.

What stays local, and what needs the internet

Selected media and captions are prepared locally. The service does not upload your film or PDF to cloud storage before casting. Desktop Chrome mirrors a locally rendered presentation; Android direct Cast sends bounded media messages to the TV; phone mirroring shares the displayed player.

The website still downloads its processing code and contacts the account service to verify playback policy. Optional analytics requires consent. “No media uploads” does not mean fully offline or no internet requests. The local-file privacy guide separates media handling from those service requests.

Keep the source device available

Keep the browser open and the source device awake. On a phone, keep the player visible and the device unlocked. Moving to another app, locking the phone or losing Wi-Fi can interrupt preparation or playback. A requested screen wake lock is helpful when available, but it is not a guarantee against suspension.

Use Stop Casting for a direct connection. In Android manual screen casting, Stop playback only stops this player: disconnect the TV in Android’s Cast controls as well. iPhone mirroring also ends through Control Centre. For the desktop chooser, see Google’s Chrome casting instructions.
