Show a photo or image on your TV

Put the picture on the screen

1. Open Cast to Your TV and drop an image onto the file area, or browse to it.
2. Wait for the selected image’s thumbnail and ready state. Preparation is automatic.
3. In desktop Chrome, press Cast and choose your Google Cast TV on the same Wi-Fi.
4. To show a different image, choose another file and press Cast again on the existing connection.

This is a one-image-at-a-time viewer. It does not upload an album, maintain a cloud library or automatically cycle through a folder. On phones, follow the Android or iPhone and iPad connection instructions.

Which image files can I select?

The app recognises JPEG, PNG, WebP, GIF, BMP, TIFF, AVIF, HEIC, HEIF and static SVG. Preparation depends on successful decoding; a recognised filename is not a guarantee that a damaged or unusual file can be rendered.

Images are shown as a PNG still. An animated GIF displays its first frame, and an image collection does not become a slideshow. For a diagram with several pages, a PDF can be more convenient because it provides page navigation. If your goal is to watch movement, select a supported video rather than an animated image.

How much image detail reaches the TV?

The browser prepares a still fitting within 3840 × 2160 pixels while preserving its aspect ratio. It reduces dimensions further if necessary to keep the rendered PNG within the 8 MiB transfer budget. It does not stretch a small photograph into new detail or fill the whole screen by cropping away its edges.

These are preparation dimensions, not a promise of 4K output. Desktop or phone mirroring can add another encoding step, and the TV’s display and connection affect the final picture. Fine text and detailed line drawings benefit from a clear original. For a blurry image, compare the source dimensions with the prepared thumbnail rather than repeatedly increasing a video-quality setting.

Large photographs and SVG safety limits

Ordinary image files have a 100 MiB input limit and a 40 million pixel decoded-image limit. Both checks matter: a small compressed file can expand into a very large image. Exporting a smaller copy can help a phone prepare an otherwise oversized camera image.

Static SVG has its own 5 MiB and 20,000-node limits. The app checks its markup before rasterizing it. Scripts, external resources, recursive references and unsupported effects are rejected. A self-contained illustration is more suitable than an SVG that depends on remote fonts, linked images or executable content. You can use a locally exported PNG if the SVG cannot be safely prepared.

If the TV is black or still shows the old image

First confirm that the current file’s thumbnail is the image you intended to select and preparation has completed. If you replaced an earlier file, press Cast for the new selection. If the TV connection is open but does not update, stop playback or casting and try the current file again.

Try a simple JPG or PNG to distinguish a connection problem from a decoder problem with one image. If no TV appears at all, use the discovery checklist; image conversion cannot fix TV discovery. Keep the browser open during the presentation. The media stays local, while loading the website and verifying playback still use network services.
