Your guide
to casting.
Your files, your devices, your TV. Find the right way to connect them, understand what works, and get back to watching.
Open the playerCast your own files from the browser
Play your own videos, music, photos and PDF pages on a TV. Choose the right browser and connection, add subtitles, and keep your media files local.
Getting startedCast from your computer with Google Chrome
Use desktop Chrome to play local videos, audio, photos and PDFs on a Google Cast TV. Follow the setup steps, subtitle controls and quality checks.
Getting startedCast from Android, with a system fallback
Cast files from Android Chrome or use Android’s built-in screen casting when its TV chooser is empty. Learn the controls, limits and correct stop steps.
Getting startedUse iPhone or iPad Screen Mirroring
Use Safari’s local player with AirPlay Screen Mirroring for videos, photos and PDFs. Check TV requirements, tap Play, and stop mirroring in Control Centre.
Files and formatsCast an MKV file to your TV
Play a local MKV on your TV with browser preparation, audio track selection and subtitles. Understand codec, large-file and casting quality limits.
Files and formatsWatch an MP4 or MOV on your TV
Cast an MP4 or MOV from your computer or phone without a media upload. Learn about automatic preparation, audio, subtitles and original-quality settings.
Files and formatsShow a photo or image on your TV
Show local photos and images on your TV without uploading them. Cast JPG, PNG, HEIC or static SVG and understand image size, quality and animation limits.
Files and formatsDisplay a PDF on your TV
Display a local PDF on your TV with browser-based page controls and no media upload. Learn how page rendering works, what stays local and the file limits.
Files and formatsPlay an audio file through your TV
Play a local audio file on your TV without uploading it. Learn supported formats, track selection, browser conversion and what to check when there is no sound.
Files and formatsWatch a local video with subtitles
Use embedded text or SRT, VTT, ASS and SSA subtitles while casting a local video. Learn track selection, text size, styling and large-file limits.
Files and formatsCast a multi-GB video without a media upload
Learn how compatible multi-GB videos stream locally in the browser, why some conversions still have a 256 MiB limit and how to reduce playback problems.
TroubleshootingWhen Chrome cannot find your TV
An empty Cast chooser can mean a discovery problem, not an unsupported file. Read connection checks, compare receivers, and use Android’s system fallback.
TroubleshootingFind where the sound stops
Work through muted playback, wrong audio tracks, MKV sound formats and phone mirroring limits. Keep discovery problems separate from missing TV audio.
TroubleshootingImprove a soft picture or interrupted playback
Understand Original, 1080p and 720p preparation, then check source decoding, local Wi-Fi and mirroring limits when TV playback looks soft or buffers.
PrivacyYour media stays local; the service still uses the internet
Learn where files, captions and PDF pages go during casting, which service requests use the internet, and what happens when you close the browser.
