Questions people actually ask

Browsers block autoplay when the video has sound. Chrome, Safari, and Firefox all require the player to be muted before they will start it without a click, so autoplay and mute have to be turned on together. Turning on autoplay here turns on mute with it, because that is the only combination a browser will honour.

On a single video, loop=1 is ignored unless the playlist parameter is also present and set to that same video ID. It is a quirk of the YouTube player rather than a bug in your code. The builder adds the playlist parameter for you whenever you turn looping on.

Not since September 2018. It used to hide related videos entirely, and a great deal of older advice still says so. Today it only restricts the suggestions to the same channel as the video you embedded. There is no longer any way to remove them completely.

No. YouTube deprecated modestbranding in August 2023 and the parameter now has no effect at all. Any tool that still offers it as a working toggle is giving you a control that does nothing, which is why it is not offered here.

It serves the player from youtube-nocookie.com instead of youtube.com. That domain does not set tracking cookies until a visitor actually starts the video, which usually keeps a plain embed out of your cookie consent banner. Playback is otherwise identical.

A standard YouTube iframe pulls in well over a megabyte of scripts and styles before anyone presses play, and it competes with your own code for the main thread. Loading a thumbnail first and only fetching the player on click avoids nearly all of that cost.

YouTube and Loom take a start time as a parameter on the embed URL, measured in seconds. Vimeo is different: it reads the start time from the URL fragment instead, in a format like 1m30s. The builder handles the difference for whichever platform you paste.

Unlisted Vimeo videos carry a privacy token in their URL, as a second path segment after the video ID. The player refuses to load without it. Paste the full link you were given rather than just the numeric ID and the token is carried across automatically.

No. The builder runs entirely in your browser and the site has no backend to send anything to. Your video link is read locally, and the configuration is kept in the page URL after the hash, which browsers never transmit to a server.

Yes. The output is yours with no attribution required and no licence attached. It is ordinary HTML, CSS, and JavaScript with no dependency on this site, so nothing breaks or phones home if this site later disappears.
