// quick guide
A QR (Quick Response) code is a type of two-dimensional matrix barcode that can be scanned by smartphones or QR readers to quickly access information. QR codes can store URLs, contact information (vCards), plain text, Wi-Fi network credentials, and emails.
How to use this tool:
- Enter the URL, text, or contact data you want to encode.
- Choose the desired Error Correction Level: Low (7%), Medium (15%), Quartil (25%), or High (30%). Higher levels allow the code to remain readable even if it is partially damaged or covered by a logo.
- Customize the colors (foreground and background) to match your brand.
- Download your generated QR code as an SVG (ideal for print and scaling) or a high-resolution PNG.
// frequently asked questions
Do these QR codes have any expiration limits or watermarks?
No. The QR codes generated by FormatMaster are completely free, have no watermark, and will never expire because they contain pure static data. There are no middleman servers or redirects involved.
What error correction level should I choose?
For sharing standard URLs, **Medium (M)** is recommended as it balances data density and scanning reliability. If you plan to add a logo in the center or use the code on objects that might get scratched, choose **High (H)**.
Can I scan these QR codes without an internet connection?
Yes. The QR code generator runs entirely in JavaScript on your device. You can download the image and scan it with any device, even offline.
