A YouTube QR code encodes a link to a video, playlist, or channel that already lives on YouTube. There is nothing to upload and nothing for you to host - you paste the URL, we generate the code, and when someone scans it with any modern smartphone camera their browser or the YouTube app opens and the video starts playing. Because the video stays on YouTube, every scan counts as a real view on your channel, and viewers land on the full YouTube page with your subscribe button, likes, comments, and recommended videos already in place.
The whole point is simplicity: if you can copy a YouTube link, you can make the code. A normal youtube.com watch URL, a youtu.be short link, a playlist link, or your channel URL all work the same way - paste it in and download the code as a PNG or SVG. There is no video editing, no file size to worry about, and no separate hosting bill, because YouTube handles all the streaming. You get a two-centimetre square that turns any printed surface into a doorway to your video.
Because QR Cake makes the code dynamic, the printed pattern is never permanently locked to a single video. If you publish a better cut, launch a new campaign, or want to point last season's flyers at this season's clip, you just open the code in your dashboard and paste a new YouTube link. Every code already printed - on packaging, posters, business cards, or handouts - immediately opens the new video, with no reprint. A static QR code bakes the URL into the pattern, so changing the video would mean reprinting everything.
