Frequently asked questions

Everything people ask about creating QR codes — from pricing and expiry to WiFi, vCards and troubleshooting scan failures. Can’t find your answer? Ask us directly.

Basics

Is this QR code generator really free?

Yes — 100% free, forever. There is no sign-up, no account, no watermark, no scan limit, and no hidden paywall. You can use the QR codes you create for personal or commercial purposes, including print, without paying anything.

How do I create a QR code?

Choose a type (URL, text, email, phone, SMS, WiFi or vCard), enter your content, customize colors and size if you like, then download as PNG or SVG. The QR code updates live as you type — there is nothing to submit and nothing to install.

What is a QR code?

A QR code (short for Quick Response code) is a two-dimensional barcode that stores information in a grid of black-and-white modules. Smartphone cameras can read it instantly — scanning a QR code can open a website, join a WiFi network, save a contact, send a message, and more.

Do I need a special app to scan QR codes?

No. Modern phones scan QR codes with the built-in camera app — iPhone (iOS 11+) and most Android phones open the camera and recognize QR codes automatically. Google Lens also works on Android.

Can I use QR codes commercially?

Yes. QR codes are free to create and use for any purpose, including business cards, menus, posters, packaging and advertising. The QR code format itself is licensed under a royalty-free patent by Denso Wave, its creator.

Static vs dynamic

What is the difference between a static and a dynamic QR code?

A static QR code encodes your content directly into the pattern, so it works forever with no subscription and no expiry — but you cannot edit it once generated. A dynamic QR code encodes a short redirect URL instead, so the destination can be changed later and scans can be tracked. Dynamic codes need a hosted service and usually a paid plan.

How long do static QR codes last?

Forever. Because the information is baked directly into the pattern, a static QR code never expires, never needs a subscription, and keeps working even if the service you used to create it disappears.

Can a static QR code be edited after printing?

No. Once a static QR code is generated, the content is permanently encoded. That is why we recommend double-checking your URL and testing the code before printing. If you expect to change the destination later, you need a dynamic QR code.

Do QR codes expire?

Static QR codes never expire. Dynamic QR codes can stop working if the subscription or hosting plan behind them lapses. Always verify before large print runs.

Customization

Can I put a logo in the middle of my QR code?

Yes. Upload your logo in the generator and it will be placed in the center. Use error correction level Q or H so the code still scans reliably with the logo covering part of the pattern.

Can I change the color of my QR code?

Yes — choose from preset swatches or pick any custom foreground and background color. Keep the contrast high (dark foreground on light background) so scanners can read the code reliably.

What error correction level should I choose?

L (7%) recovers the least data, H (30%) the most. Use Q or H when adding a logo or printing on textured surfaces; L or M is fine for simple black-on-white codes. Higher levels make the pattern denser but more resilient.

Should I download PNG or SVG?

Use SVG for print and anything that must scale without losing quality — it is a vector format. Use PNG for digital use such as websites, emails and social media. Our generator offers both.

How do I create a QR code for WiFi?

Select the WiFi type, enter your network name (SSID) and password, choose the encryption type (WPA/WPA2, WEP or no password), and download the code. Scanning it connects a phone to your network instantly.

How do I create a QR code for a vCard?

Select the vCard type and fill in the name, organization, phone, email, website and notes you want to share. Scanning the code offers to save the contact straight to the phone’s address book.

Can I create a QR code without an internet connection?

Once the page is loaded, the generator runs entirely in your browser. All QR codes are created client-side, so your content never leaves your device.

Troubleshooting

Why is my QR code not scanning?

Most issues come from low color contrast, a missing quiet zone, a logo that is too large, or printing at too small a size. Test the code with your phone camera before printing, and keep the foreground and background colors clearly distinct.

Is my data private when I use this generator?

Yes. Everything runs in your browser — your URLs, text, WiFi passwords and contacts are encoded locally and never uploaded to a server. There is no account, no backend and no tracking on this site.

What is the maximum amount of text a QR code can hold?

A version-40 QR code can store up to about 2,953 bytes — roughly 7,000 digits or 4,296 alphanumeric characters. For practical purposes, keep URLs and text under a few hundred characters for dense, easy-to-scan codes.

Can QR codes be scanned if part of them is damaged?

Yes, thanks to Reed–Solomon error correction. Higher error correction levels (Q or H) let the code survive more damage, dirt, or a logo placed in the center before it becomes unreadable.
