Frequently Asked Questions

What is a QR code?
QR (Quick Response) code is a two-dimensional barcode capable of storing various data like URLs, text, or contact information. Scanning it with a smartphone camera provides instant access to the embedded information.
Can I use the QR codes I generate here commercially?
Yes! All QR codes generated with QR Studio are completely free for both personal and commercial use. There are no watermarks, usage limits, or attribution requirements.
Do my QR codes expire?
No. The QR codes generated here are static (the data is embedded directly into the code pattern). As long as the content you linked to (like a website) remains active, they will work forever.
Can I add my company logo to my QR code?
Absolutely! Just upload your logo via the "Customize" panel. Your logo will be placed right in the center. We recommend using a higher error correction level (Q or H) when adding a logo to ensure it remains scannable.
Which format should I download?
PNG: Best for general web, social media, and document use.
SVG: Vector-based, offering perfect scaling for print and large-format designs.
JPEG: A compressed alternative for email attachments and web usage where file size is critical.
Where do the QR code photos I scan go?
Nowhere. Your data never leaves your browser. QR Studio operates entirely on your device (client-side) with no server connectivity for processing. No images are saved or uploaded. Your privacy is 100% secure.
