Frequently Asked Questions

What QR code types do you support?

We support 11 QR types: plain text, URLs, phone numbers, SMS, email, calendar events, vCards, MeCards, tweets, Wi-Fi credentials, and SEPA bank transfers. Each generates a downloadable PNG instantly.

How does the YouTube tag generator work?

Enter your video title and the tool extracts relevant keywords, generates SEO-optimized tag combinations, and suggests related tags. It uses AI-powered extraction when an API key is configured, falling back to n-gram analysis for fast client-side results.

Is there a limit on how many QR codes I can generate?

No limits. You can generate unlimited QR codes, YouTube tag sets, and passwords. All three tools run in your browser with no server calls, no sign-up, and no usage caps.
