Do Plain Text QR codes work without an internet connection?

Yes! Because the text payload is encoded directly into the QR pattern, smartphone cameras can scan and display the text offline without cellular data or Wi-Fi.

Are the QR codes generated on WDBloog 100% free forever?

Yes! All QR codes generated on qr.wdbloog.com are 100% free for commercial and personal use with unlimited scans. There are no scan limits, hidden fees, or subscription locks.

Do these QR codes expire?

No. Standard static QR codes created on WDBloog contain direct encoded payload data (such as your URL, Wi-Fi credentials, or vCard) and will never expire as long as your destination link or info remains active.

Can I download vector SVG format for printing?

Absolutely! WDBloog supports resolution-independent SVG vector export as well as ultra high-resolution PNG (up to 2048x2048px) and print-ready PDF files ideal for billboards, business cards, and flyers.

Is my data private and secure?

Yes. All QR code generation is processed 100% client-side inside your browser. Your sensitive information (Wi-Fi passwords, contact details, private URLs) is never sent to or stored on external servers.

How do I add my custom business logo inside the QR code?

Simply select the "Center Logo" tab in our customization panel. You can pick from built-in brand icons (Wi-Fi, WhatsApp, Bitcoin, Contact, etc.) or upload your own PNG/SVG logo image. We automatically boost error correction to level H for flawless scanning.

QR Code Technology & Terms Explained

What is QR Code Error Correction (Level H)?: Reed-Solomon error correction allows QR codes to remain scannable even if up to 30% of the symbol is covered by a custom central logo image or scratched on printed paper.
Why Choose Vector SVG over PNG for Commercial Printing?: SVG (Scalable Vector Graphics) is a resolution-independent format composed of math vectors. It can be scaled to billboard dimensions without pixelation or blurriness.
What is Client-Side QR Generation?: Client-side generation executes encoding algorithms directly inside your web browser engine. Your Wi-Fi passwords, vCard details, and private links are never transmitted across the web.
Are Static QR Codes Safe from Expiration?: Yes! Static QR codes directly encode data into the matrix dots. Unlike dynamic QR codes that rely on third-party tracking links, static QR codes work indefinitely for free.
