How to use QR Code Generator Pro

  1. Choose what the code should do

    A URL, plain text, Wi-Fi credentials, a contact card or a phone number. The type determines how the scanning phone reacts.

  2. Enter your content

    Keep URLs short — the more data a code holds, the denser and harder to scan it becomes.

  3. Customise if you need to

    Adjust colours and add a logo. Keep strong contrast between the code and its background.

  4. Download and test

    Test with at least two different phones before printing anything. This step is not optional.

When to use QR Code Generator Pro

  • Putting a menu or price list online and linking to it from a table card
  • Sharing Wi-Fi access with guests without reading out a password
  • Adding a link to a poster, flyer or business card
  • Linking to an event page or booking form from printed material

FAQ

Yes. Upload an image and it will be centred inside the QR code. Higher error correction levels ensure the code stays scannable.
Error correction lets the QR code remain scannable even if part of it is obscured. Level H (30%) is best when adding a logo; Level L (7%) is fine for clean codes.
No. QR codes encode data directly, so they work forever. However, if the encoded URL changes or goes offline, the destination will not be reachable.
A static code contains the data itself and works forever. What can break is the destination — if the URL stops working, the code still resolves to a dead link. Dynamic codes that redirect through a third party can stop working if that service does.
About 2×2 cm for close scanning. Scale up with distance — roughly one tenth of the scanning distance as a rule of thumb, so a poster read from two metres needs a code around 20 cm across.
Yes, because error correction tolerates part of the code being obscured. Keep the logo under about 30% of the area and raise the error correction level, then test on several devices.
The usual causes are insufficient contrast, an inverted colour scheme, a missing quiet zone, printing too small, or too much data making the pattern too dense. Test before committing to print.

About QR Code Generator Pro

A QR code is just an encoding of text. Everything else — opening a website, joining a network, saving a contact — is the scanning phone recognising a pattern in that text and offering the matching action. A URL becomes a link because it starts with https://, not because the code is a special kind.

The single most important property is contrast, and the most common failure is inverting it. Scanners expect dark modules on a light background. A light code on a dark background fails on many devices, and so does a code printed too small or without the surrounding quiet zone — the blank margin is part of the specification, not decoration.

Error correction is the reason a logo can sit in the middle of a code at all. Higher correction levels let more of the code be obscured or damaged while remaining readable, at the cost of a denser pattern. If you are adding a logo or printing somewhere the code might get scuffed, raise the error correction.

Tips and limits

  • Test with at least two phones, iOS and Android, before printing anything.
  • Keep dark-on-light. Inverted codes fail on many scanners.
  • Leave the quiet zone — the blank margin is part of the spec.
  • Minimum practical print size is about 2×2 cm, and larger if it will be scanned from a distance.
  • Shorten long URLs first: fewer characters means a less dense, more reliable code.
