Frequently Asked Questions
How do I make a YouTube video autoplay on my website?
Toggle Autoplay on. Modern browsers block autoplay with sound, so the tool automatically enables Mute alongside Autoplay — that's the only way autoplay reliably triggers across Chrome, Safari, and Firefox.
What does no-cookie privacy mode actually do?
It switches the embed domain to youtube-nocookie.com. YouTube won't set tracking cookies until the user actively plays the video. Recommended for GDPR/CCPA-conscious sites.
Why does Modest Branding still show the YouTube logo?
YouTube partially deprecated modestbranding=1 in 2023 — the parameter still removes the watermark in the player corner but the YouTube logo on the control bar always remains. The tool toggles the parameter for backward compatibility.
Can I make the embed loop a single video?
Yes. Toggle Loop on. The tool automatically pairs loop=1 with playlist={videoId}, which is YouTube's required workaround to make a single-video loop actually work.
How do I make the embed responsive?
The generated iframe uses fixed width and height by default. Wrap it in a container with padding-bottom: 56.25% (16:9) and absolutely position the iframe to fill it — the tool's preview demonstrates this pattern.
Is the generated code accessibility-friendly?
Yes. The iframe includes a title attribute (set from the video URL), loading="lazy" for performance, allowfullscreen, and the standard allow attribute that supports picture-in-picture and accelerometer.
Does this work for YouTube Shorts?
Yes. Paste any youtube.com/shorts/ID URL and the tool extracts the video ID. Shorts embed in iframes the same way as regular videos.
Are my URLs sent to a server?
No. All parsing and embed generation happens in your browser. The recents list is cached locally and never leaves your device.
