Question 1

Is my data safe with this QR Code generator? Are my inputs saved on any server?

Accepted Answer

Completely safe! This tool runs 100% on the client-side (Browser-Based). All encoding, image generation, and card processing occur entirely within your browser. Your input text, contact details, and uploaded logos are never sent or stored on any server, ensuring total privacy and zero tracking.

Question 2

Will embedding a center Logo cause QR Code scanning to fail?

Accepted Answer

No. QR Codes feature built-in Error Correction. When you upload a Logo, this tool automatically boosts error correction to Level H (30%), allowing smartphones to scan and decode the QR code reliably even with up to 30% center coverage.

Question 3

Why is vector SVG format recommended over PNG or WEBP?

Accepted Answer

SVG is a resolution-independent vector format that scales endlessly without pixelation, ideal for large print, billboards, and design software (Illustrator/Figma). Inline SVG also reduces HTTP requests, boosting website Core Web Vitals and SEO performance. PNG and WEBP are raster formats; WEBP offers superior compression for web image SEO, while PNG provides lossless transparency for social sharing.

Question 4

Do generated QR Codes expire or have scan limits? Is it really free?

Accepted Answer

100% free and permanent! All QR Codes generated are static codes where data is encoded directly into the matrix without redirect servers. There are no scan limits, no expiration dates, and zero ads. As long as your destination link remains valid, the QR code will work forever.

Question 5

How do I create a vCard QR Code that saves contact info automatically?

Accepted Answer

Select the "Contact vCard" tab and enter your details to generate a standard vCard QR Code. Smartphone cameras will prompt "Add to Contacts" when scanned. Note: Due to OS security policies on iOS/Android, camera scanning alone may omit extended fields like addresses or notes. We recommend using our "Download .vcf Contact File" button to send a .vcf file directly for 100% full-field contact import.
