Frequently Asked Questions
Is Pure QR completely free, and will my QR codes ever expire?
Yes. Pure QR is 100% free with no hidden paywalls, subscriptions, or scan limits. All codes generated are standard static QR codes, meaning your destination data is encoded directly into the code and will never expire.
Why do other QR websites deactivate codes after 14 days or demand $15–$50/month?
Most commercial generators create "Dynamic QR codes" routed through their private redirect servers. Once you have printed your flyers, business cards, or menus, they deactivate the redirect link and hold your materials hostage until you pay a monthly subscription. Pure QR creates pure Static QR codes where your data is etched directly into the visual matrix. Without intermediate servers, your codes cannot be hijacked, altered, or deactivated.
How does Pure QR stay completely free without subscriptions or selling personal data?
Pure QR operates on radical transparency: we display exactly 1 modest sponsor advertisement slot per visit to cover server hosting and global CDN bandwidth. We never sell user data or profile you. We only gather anonymous usage statistics to make Pure QR better for you. You can also support our independent development through our optional Ko-fi tip jar.
Are my data and privacy secure?
Absolutely. All QR codes are generated locally inside your browser using HTML5 Canvas and SVG APIs. No data is ever sent, collected, or stored on external servers.
Can I use Pure QR's exported SVG vector for commercial printing, signage, or laser engraving?
Yes. In addition to high-resolution PNGs up to 4096×4096px, Pure QR provides infinite-resolution vector SVG exports for free. SVG vector files scale without any pixelation or blurriness, making them ideal for Adobe Illustrator, Figma, vinyl cutters, laser engravers, and building-sized banners.
Does it support international languages and complex character sets?
Yes. Pure QR features full UTF-8 encoding support. This guarantees that complex scripts, including Arabic, Chinese, Japanese, Hebrew, and Vietnamese accents, scan reliably on any smartphone.
Can I scan a QR code from a screenshot or image file on my PC?
Yes! Our built-in QR scanner lets you upload any image file, paste directly from your clipboard (Ctrl+V), or drag and drop a screenshot. It decodes the QR code instantly without needing a mobile phone camera.
Can this tool extract Wi-Fi passwords and contact details (vCards) from QR codes?
Absolutely. The smart scanner automatically detects Wi-Fi networks, vCard contacts, emails, and URLs. It allows you to download scanned contacts as a .vcf file or copy Wi-Fi credentials with one click.
Is it safe to scan private QR codes here, and does it support complex/transparent designs?
Yes, it is 100% private. All scanning occurs locally in your browser using an advanced multi-scale engine; your images are never uploaded. It also easily decodes complex QR codes with rounded corners, custom logos, or transparent backgrounds.
Will I lose my custom QR code design if I accidentally refresh or close the tab?
No. Your progress is automatically protected. Our generator auto-saves your custom styling, logos, and content locally in your browser for 24 hours without requiring an account. If you refresh or close the tab, your draft is restored instantly. To start fresh, use the accident-proof 2-step "Reset" button above the editor.
Can I install Pure QR on my iPhone or Android home screen like an app?
Yes! Pure QR is a Progressive Web App (PWA). You don't need the App Store. On iPhone (Safari), tap the Share icon and choose 'Add to Home Screen'. On Android (Chrome), tap the three dots and select 'Install App' or 'Add to Home screen'. It opens full-screen without address bars, requires 0 MB of App Store downloads, and runs instantly.
