More details & FAQ

Why this page is a QR workflow hub

The homepage is designed to help you choose the right QR format before you create anything. Different use cases have different failure points: WiFi QR codes depend on SSID accuracy, vCard QR codes depend on contact import quality, email QR codes depend on mail app compatibility, and PDF QR codes depend on stable hosted URLs. A single generic page should not pretend those workflows are identical.

Use the cards below to move into the focused generator page for the format you actually need. Each dedicated page carries the deeper FAQ, support guides, and testing advice for that query family, while this hub stays responsible for navigation, format comparison, and high-level best practices.

How to choose and ship the right QR code in 3 steps

  1. Pick the correct workflow: WiFi, vCard, email, PDF, general link, or text, depending on what should happen after the scan.
  2. Use the dedicated page for that format: Enter the exact payload, follow the format-specific guidance, and avoid copying one workflow into another.
  3. Export and test the final asset: Download PNG or SVG, then check scanning on at least one iPhone and one Android device before public rollout.

What stays true across every QR workflow

  • Use strong contrast and leave enough quiet zone around the code for reliable camera detection.
  • Add a clear scan instruction such as "Scan to join WiFi" or "Scan to save contact" so the outcome is obvious.
  • Use PNG for quick digital placement and SVG for print, packaging, flyers, posters, or other high-resolution output.
  • Test the actual destination, not just the symbol. A code can scan perfectly while the WiFi, email, or PDF workflow still fails.
  • When the destination may change over time, control a stable URL or a repeatable replacement process before printing at scale.

Frequently Asked Questions (FAQ)

Is this the page I should optimize around every QR query?

No. Use this page to choose the right workflow. The dedicated WiFi, vCard, Email, and PDF pages are the stronger targets for their specific search intent and conversion path.

Do QR codes expire?

Static QR codes do not expire. They only stop working if the destination content (for example a web page) is removed or changed.

Is my data secure?

Yes. Generation happens in your browser, and the site does not rely on a custom backend workflow to assemble your QR payload.

Which format should I download: PNG or SVG?

Use PNG for quick digital use. Use SVG for print and large-size designs, because vectors stay sharp at any size.
