What can I encode in a QR code?

Any text: URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS (smsto:), Wi-Fi credentials, or vCards.

What error correction level should I use?

M (15%) is a good default. Use H (30%) if you plan to print the QR code in conditions where it might get dirty or partially covered.

Is this tool free to use?

Yes. All Skybin developer tools are free with no account, API key, or usage limits.

Does my data get sent to a server?

No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).

Can I use this on mobile?

Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.

How is this different from desktop apps?

There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.

Are there keyboard shortcuts?

Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.

Does Skybin store my history?

No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.

Error correction levels

QR codes have four error correction levels: L (7%), M (15%), Q (25%), H (30%). Higher levels allow the QR code to be scanned even if part of it is obscured or damaged — but produce a denser image.

Why use QR Code Generator online?

QR Code Generator in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.
