YouTube Embed Code Generator

This generator builds the iframe code YouTube's embedded player expects, with the options set as URL parameters from Google's official player parameter reference. Start and end take a time in any common format and become start= and end= in seconds; both are measured from the beginning of the video. Autoplay adds autoplay=1 and mute=1, loop adds the playlist parameter it needs, controls=0 hides the control bar, cc_load_policy=1 shows captions by default, playsinline=1 keeps playback inline on iPhones, and rel=0 limits the related videos shown to the same channel.

Privacy-enhanced mode swaps the host to youtube-nocookie.com. YouTube describes it as keeping views in the embed from influencing the viewer's YouTube recommendations and ad personalization; it does not stop the visitor's browser from connecting to YouTube when the player loads. The generated code also includes referrerpolicy="strict-origin-when-cross-origin", which YouTube recommends so the embedded player can identify the site it runs on, plus the allow list YouTube's own Share > Embed code uses and allowfullscreen.

For layout, the responsive option wraps the iframe in a div that keeps a 16:9 shape at any width, using the CSS aspect-ratio property that current browsers support. Fixed mode keeps plain width and height attributes; YouTube's minimum player size is 200 × 200 pixels, and it recommends at least 480 × 270 for 16:9. A descriptive title attribute helps screen reader users, and loading="lazy" lets the browser wait until the player is near the visible area, which saves bandwidth on long pages.

The page is careful about outside requests: the code is put together locally from the video ID and your choices, and no thumbnail, script or player loads from YouTube until you press Load preview. Parameters YouTube has retired, such as modestbranding and showinfo, are left out because they no longer do anything.
