Is this free and unlimited?

Yes. Generation runs in your browser — no rate limits, no signup, no watermark.

What error correction level should I use?

L (7%) for clean digital use, M (15%) for print, Q (25%) if adding a logo, H (30%) for damage-prone environments.

Can I encode WiFi credentials?

Yes. Use the format WIFI:T:WPA;S:NetworkName;P:Password;; and paste it as the QR content.

PNG for general sharing. SVG for printing, scaling to any size without quality loss, or embedding in vector design tools.

Why should I never put a tracking-shortened URL inside a printed QR code?

If the shortener disappears (service shuts down, account deleted), your printed posters become dead links. For permanent print, encode the canonical destination URL directly — even if it's longer.

When is a QR code the right call vs. a short URL?

QR codes win when scanning beats typing — physical signs, restaurant menus, business cards, museum exhibits, payment requests, WiFi sharing. Short URLs win for verbal sharing or text/email contexts.
