Frequently Asked Questions
Answers to common questions about QRSaved code generation, durability, printing formats, and privacy.
General & Functionality
Do QRSaved codes ever expire or stop working?
Never. QRSaved generates static QR codes where your data (URLs, WiFi passwords, contact info) is encoded directly into the black-and-white module matrix. Because there is no redirection server or intermediate link involved, your QR code will continue to function indefinitely for life.
Is QRSaved really free with no scan limits?
Yes, 100% free with unlimited scans forever. Many commercial QR services lure users with "free" codes that secretly expire after 14 days unless you pay a monthly fee. QRSaved does not employ any paywalls or tracking redirects.
Is my data secure and private on QRSaved?
Yes. All generation happens locally in your browser (Client-Side) using JavaScript and HTML5 Canvas. Your WiFi passwords, vCards, and notes never leave your computer or phone.
Customization & Logos
Can I add a custom company logo in the center?
Yes! Navigate to the "Colors & Design" tab, click the upload logo box, and pick any PNG, JPG, or SVG image. QRSaved automatically centers your logo with a clean background shield and sets Error Correction to High (30%) so phone cameras can scan it without issue.
What is Error Correction Level (L, M, Q, H)?
QR codes use Reed-Solomon error correction to recover data even if parts of the code are dirty, scratched, or covered by a logo: L (7% recovery), M (15% recovery, default), Q (25% recovery), and H (30% recovery, maximum). When you upload a logo, H is automatically enabled.
Can I use custom brand colors?
Yes. You can select from our curated high-contrast palettes or input any custom Hex color code. QRSaved also features a real-time WCAG contrast checker to warn you if your foreground and background colors are too similar for cameras to distinguish.
Printing & File Formats
Which format should I use for printing: PNG or SVG?
For print materials (flyers, banners, billboards, business cards, vehicle wraps), always use Vector SVG. SVG files are resolution-independent and can be scaled to any size—even the side of a building—without losing sharpness. For websites and digital sharing, PNG is ideal.
What size should I print my QR code?
A good rule of thumb is a 10:1 distance-to-size ratio. For example, if someone will scan your code from 10 inches away (like a business card or restaurant menu), make the code at least 1 inch (2.5 cm) wide. For a poster scanned from 6 feet away, make it at least 7 inches wide.
