Frequently Asked Questions

Everything you need to know about QR codes

What is a QR code?

QR (Quick Response) code is a 2D barcode that stores data like URLs, text, or contact info. Scan with any smartphone camera to instantly access the encoded information.

How to create a QR code for free?

Enter your data (URL, text, WiFi credentials, vCard, etc.), customize colors and style if desired. Your QR code is created instantly in real-time and ready to download - completely free, no registration needed.

Can I add a logo to my QR code?

Yes. Upload your logo or image (up to 5MB), adjust its size and position. The error correction ensures the QR code remains scannable with your branding embedded in the center.

What file formats are available for download?

Download your QR code as PNG (up to 4000px), SVG, JPG, WebP, or PDF. Vector formats (SVG, PDF) scale to any size without quality loss - ideal for print, signage, and packaging.

Do QR codes expire?

Static QR codes never expire. They work indefinitely as long as the encoded content (like a URL) remains valid. No server dependency, no subscription required.

Can I generate multiple QR codes at once?

Yes. Use the batch generation feature to create multiple QR codes from CSV files, or use serial generation for numbered sequences (tickets, inventory labels, ID badges).

Can I save my QR code designs?

Yes. Save custom styles as presets and access your generation history anytime. All data is stored locally in your browser via IndexedDB for privacy.

Is my data safe?

All QR codes are generated locally in your browser using client-side JavaScript. No data is sent to any server. Close the tab and all data is released.

Technical Details

QR code generation engine specifications

ISO/IEC 18004:2015 Compliant

Every QR code passes structural validation per ISO/IEC 18004:2015 before export. Universal scanner compatibility - tested across iOS Camera, Android Lens, and dedicated industrial barcode readers. No proprietary encoding.

Reed-Solomon Error Correction (ECC)

Four ECC levels: L (7% recovery), M (15%), Q (25%), H (30%). Level H allows up to 30% of the code to be damaged or obstructed while remaining scannable - required for printed materials, outdoor signage, and logo-embedded QR codes.

4000px Raster & Vector Export

High-resolution 4000px PNG for CMYK print workflows. Lossless SVG and PDF vector output for infinite scaling - business cards, restaurant menus, billboards. JPG and WebP for web embedding. All formats generated client-side in a single pass.

Zero-Storage Policy

Pure client-side JavaScript processing in volatile memory. No data transmitted to any server. No values persist beyond the browser tab, no server-side logs, zero server-side copies. Close the tab and everything is gone. Zero registrations required.

Encoding Capacity

Numeric: up to 7,089 digits. Alphanumeric: 4,296 characters. Binary/UTF-8: 2,953 bytes. Automatic mode selection optimizes density vs. scan reliability. Supports URL, vCard, WiFi (WPA/WPA2/WPA3), email, SMS, and plain text encoding.

Batch & Serial Generation

Mass-produce up to 500 unique QR codes from a single CSV upload for inventory tracking and asset management. Serial generation creates numbered sequences for tickets, labels, and ID badges. Each code individually rendered at consistent quality.
