Setting Up tvg-logo and Icons in M3U Playlists

A visual TV guide requires channel icons. The tvg-logo attribute tells your media player where to download each icon.

The tvg-logo Attribute Format

Inside the `#EXTINF` line, write `tvg-logo="https://server.com/logos/cnn.png"` with double quotes around the image path.

Updating Logo URLs in Bulk

The current bulk URL replacement changes the channel's stream URL, not the `tvg-logo` attribute. Logo values can be inspected in the parsed attributes, but there is no dedicated bulk logo-URL editor in the present interface. For a large logo migration, convert to CSV, edit the `tvg-logo` column carefully, then import the CSV and verify several rows before export.

Why Icons Fail to Display

If the URL lacks SSL (http instead of https), security protocols on Android TV or Apple TV players might block the image.

Validating Image Dimensions

Choose square or 16:9 ratio PNG icons. Avoid loading large file sizes (keep logos under 50KB) to ensure rapid guide scroll speeds.

Logo retrieval happens in the player

tvg-logo stores a URL; the M3U file does not embed the image. The target player decides when to request it, what formats it supports, whether it blocks HTTP, and how it caches failures. Test with an authorized HTTPS example URL.

M3U Studio sanitizes dangerous protocols for logo attributes but has no dedicated bulk logo editor. CSV round trips can update the tvg-logo column, with the usual metadata-loss cautions.
