Question 1

Is this QR code generator free to use?

Accepted Answer

Yes, the Roughtools QR Code Generator is completely free with no account, watermarks, or usage limits. You can generate unlimited QR codes for URLs, WiFi networks, contact cards, emails, SMS, phone numbers, and plain text. All QR codes are generated locally in your browser using the open-source qrcode.react library, so nothing is transmitted to any server.

Question 2

Do I need to sign up to download QR codes?

Accepted Answer

No sign-up, email, or account is required at any stage. Generate your QR code, download it as SVG or PNG, and use it immediately. Your QR code content — whether it is a private WiFi password, phone number, or contact details — never leaves your device. The download happens entirely in the browser without any server communication.

Question 3

Is my QR code content stored or transmitted anywhere?

Accepted Answer

No. All QR code generation happens locally in your browser using the qrcode.react JavaScript library. Your WiFi passwords, phone numbers, email addresses, and any other content you enter are not sent to Roughtools servers at any point. Once you close the tab, the data is gone. There is no backend, no analytics on QR content, and no logging of what you generate.

Question 4

Does the QR code generator work on mobile and tablet?

Accepted Answer

Yes, fully. The QR Code Generator is responsive and works on all modern smartphones and tablets. You can generate QR codes on mobile and share them directly. The download buttons produce PNG files compatible with all standard QR code scanners including Apple's built-in camera app, Google Lens, and all dedicated QR reader apps. For WiFi QR codes, Android 10+ and iOS 11+ can scan and connect automatically.

Question 5

Which browsers support this QR code generator?

Accepted Answer

The tool works in all modern browsers: Chrome, Firefox, Edge, Safari, and Opera. Both desktop and mobile versions are supported. The SVG download works in all browsers. The PNG download uses the HTML Canvas API, which is supported in Chrome 4+, Firefox 2+, Safari 3.1+, and Edge 12+. Internet Explorer is not supported.

Question 6

How do I create a WiFi QR code for my network?

Accepted Answer

Select "WiFi" as the QR type. Enter your network SSID (the exact network name as it appears on your devices), your WiFi password, and select the security type (WPA/WPA2 for most modern routers, WEP for older networks, or None for open networks). Toggle "Hidden Network" if your SSID is not broadcast publicly. The generated QR code, when scanned by a phone, will automatically offer to connect to the network without typing the password.

Question 7

How accurate are the QR codes? Will they scan reliably?

Accepted Answer

The QR codes are generated to the ISO/IEC 18004 standard using the qrcode.react library, which is tested and used by millions of applications worldwide. The error correction level you choose determines scan reliability — Medium (15%) is recommended for most uses, while High (30%) is ideal for printed materials or when adding a logo overlay. Higher error correction allows the QR to remain scannable even if part of it is obscured, damaged, or printed at lower quality.

Question 8

How do I download my QR code as PNG or SVG?

Accepted Answer

After generating your QR code, click "Download PNG" for a raster image (best for printing and sharing) or "Download SVG" for a scalable vector format (best for large-format printing, logos, and editing in Illustrator or Inkscape). Both download options save the file directly to your device with no watermarks. The PNG download renders at your chosen size. SVG files scale to any size without quality loss.

Question 9

What is error correction level and which should I choose?

Accepted Answer

Error correction (EC) level determines how much of the QR code can be damaged or obscured while still scanning correctly. Level L (7%) produces the smallest QR code. Level M (15%) is the standard recommendation for most uses. Level Q (25%) is suitable when you plan to add a logo or icon in the centre. Level H (30%) provides maximum damage resistance and is best for QR codes on textured surfaces, curved objects, or outdoor signage that may be partially obscured.

Question 10

Why should I use Roughtools QR code generator?

Accepted Answer

Roughtools QR Code Generator supports 7 QR types in one place — including WiFi, vCard, email, SMS, and phone — while most free tools only support URLs. All generation is client-side with no watermarks, no account, and no limits. You get full control over size (128–512px), foreground and background colour, and error correction level. The SVG and PNG download options make it suitable for professional use in print, digital, and product packaging contexts.
