Is there any scan limit on my generated QR codes?

No, there are zero scan limits. Your QR codes can be scanned millions of times with no restrictions.

How do WiFi QR codes work?

When scanned by an iPhone or Android camera, a WiFi QR code prompts the user with 'Join Network?'. Tapping it connects their device automatically without typing the password.

Which format is better for printing: PNG or SVG?

Vector SVG is superior for printing on business cards, posters, and billboards because it scales to any size without losing crispness. PNG is ideal for web and digital displays.

What is Error Correction Level in QR codes?

Error correction allows a QR code to be scanned even if part of it is damaged, dirty, or covered. Level H allows up to 30% data recovery.

Can I customize the colors of my QR code?

Yes! You can choose custom colors for the QR code pixels and the background to match your brand.

Is my data or WiFi password saved on your server?

No. All QR code generation takes place 100% locally in your browser memory. Your data is never saved or sent to any server.

Does this tool work on mobile phones?

Yes, you can generate and download QR codes directly from your smartphone browser.

Is this QR code generator completely free?

Yes, 100% free with unlimited generations and no watermarks.

Can I create a vCard QR code for my contact details?

Yes, select 'Contact vCard' and enter your name, phone, email, and website to create a scannable contact card.

Why do some online QR generators stop working after a few weeks?

Many commercial websites create 'dynamic' QR codes that redirect through their proprietary servers, which they disable unless you pay a monthly fee. WebPixa generates pure static codes that never break.

What size should a printed QR code be?

For business cards, minimum 0.8 x 0.8 inches (2 x 2 cm). For flyers and posters, 1.5 to 2 inches (4 to 5 cm) is recommended for easy scanning.

Complete Guide & Overview of QR Code Generator & Scanner

Understanding capabilities, performance, and best practices

Quick Response (QR) codes have become ubiquitous in physical marketing, restaurant digital menus, product packaging, event ticketing, contactless WiFi sharing, and digital payments. Whether you need a crisp QR code for a printed billboard, a business card with your digital contact vCard, or a table-top stand for your cafe's WiFi network, WebPixa QR Code Generator provides high-resolution static QR code creation. Unlike predatory QR code generators that create dynamic redirect links that expire after 14 days or demand monthly subscription fees to keep your codes active, WebPixa generates 100% permanent, static QR codes. The encoded data is baked directly into the black-and-white matrix, ensuring your QR codes work forever without expiration, redirection, or third-party tracking. Customize foreground and background colors to match your brand palette, select high Reed-Solomon error correction (up to 30% damage tolerance) for printed merchandise, and download crisp PNG images or infinite-resolution vector SVG files.

100% Client-Side In-Memory Execution:This tool runs completely inside your web browser. Files, documents, and inputs are never transmitted, stored, or processed on remote cloud servers.

Troubleshooting & Pro Optimization Tips

Quick solutions to common edge cases and best practices

Phone camera cannot scan the colored QR code.

Ensure high contrast between the foreground and background (e.g. dark colors on light backgrounds). Avoid light yellow or grey on white.

WiFi QR code does not auto-connect.

Ensure the SSID network name and password match your router exactly, and select the correct security type (WPA/WPA2/WEP).
