Enter just your username (with or without the @). Generates instagram.com/username.

Enter a username or a full Facebook URL. If only a username is entered, facebook.com/username is used.

Enter your username or paste the full LinkedIn profile URL. A plain username generates linkedin.com/in/username.

Enter your Telegram username (with or without the @). Generates t.me/username.

Paste your channel URL (e.g. youtube.com/@channelname) or a specific video link.

Paste either an Apple App Store or Google Play Store link. For both platforms, use a universal link service (e.g. linktr.ee) in the URL field instead.

This embeds the image itself as the scanned data — there's no server, so a QR code's entire capacity is a hard ceiling: about 2.9 KB at error correction L, down to 1.2 KB at H, before base64 overhead. That fits a small icon, not a photo. For anything bigger, host the image somewhere and use the URL content type to link to it instead.
