Häufige Fragen
What is this tool?
This is a QR (Quick Response) Code Generator that allows you to create custom 2D barcodes for various data types, including URLs, text, Wi-Fi credentials, and contact information.
What types of data can I encode?
You can encode website URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi login details, and vCards (contact information).
What is Error Correction Level?
Error correction allows the QR code to be readable even if it is damaged or dirty. There are four levels: Low (L), Medium (M), Quartile (Q), and High (H). Higher levels allow more damage recovery but make the code denser.
Can I change the colors of the QR code?
Yes, you can customize the foreground and background colors. However, ensure there is high contrast between the two (e.g., dark on light) so scanners can read the code easily.
Is there a limit to the size of the QR code image?
While the digital file size is flexible, the physical dimensions matter for scanning. We recommend generating images that are at least 2cm x 2cm (approx. 0.8 inches) for reliable scanning.
Are the generated QR codes static or dynamic?
This tool generates static QR codes. This means the data is encoded directly into the image and cannot be changed later. If you need to update the destination URL in the future, you would need a dynamic QR code service.
