Frequently Asked Questions
What is a QR code and how does it work?
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information. When scanned with a smartphone camera, it quickly directs users to websites, text, contact information, or other data. QR codes work by encoding information in a pattern of black and white squares that can be read by QR code scanners.
Is FreeQR.co really free? Are there any hidden fees?
Yes, FreeQR.co is completely free with no hidden fees or catches. Unlike many other QR code generators, we don't charge for features, impose expiration dates, or require registration. Our mission is to keep QR codes accessible to everyone, forever.
What types of QR codes can I create?
You can create various types of QR codes including: URLs, text messages, contact information (vCard), WiFi credentials, email addresses, phone numbers, and more. Each type serves a different purpose and can be customized with colors and logos.
How do I customize my QR code?
You can customize your QR code by changing its colors, adding your logo, and adjusting the error correction level. Our generator provides a simple interface to make these changes while ensuring your QR code remains scannable.
What file formats can I download my QR code in?
You can download your QR code in both PNG and SVG formats. PNG is perfect for digital use, while SVG is ideal for printing as it maintains perfect quality at any size.
Do my QR codes expire?
No, QR codes generated with FreeQR.co never expire. Once created, they will work indefinitely as long as the destination content (like a website) remains available.
How can I track QR code scans?
While FreeQR.co doesn't include built-in tracking (to maintain privacy), you can use URL shorteners or analytics tools with your destination URLs to track scans. This is particularly useful for marketing campaigns.
What's the difference between PNG and SVG downloads?
PNG is a raster format perfect for digital use, while SVG is a vector format that maintains perfect quality at any size, making it ideal for printing. SVG files are also typically smaller in size and can be edited with vector graphics software.
Can I add a logo to my QR code?
Yes, you can easily add your logo to the center of your QR code. We automatically adjust the error correction level to ensure your QR code remains scannable with the logo. This is great for branding and making your QR codes more recognizable.
What is error correction and why does it matter?
Error correction allows QR codes to remain scannable even if they're partially damaged or obscured. Higher error correction levels (like 'H') are recommended when adding logos or when the QR code might be subject to wear and tear.
