Bug Reports
If a tool is not working correctly — for example, a generated QR code does not scan reliably, or a decoded QR produces unexpected output — please include:
- Tool name — e.g., "QR Code Generator" or "WiFi QR Code"
- Browser and version — e.g., "Chrome 124 on Android 14" or "Safari 17 on iPhone iOS 17.4"
- What you were trying to do — the content type and settings you used
- What happened instead — the specific failure (would not scan, wrong decoded text, download failed, etc.)
- Device used for scanning — if a generated QR failed to scan, noting the phone model and OS helps narrow down the issue
Feature Requests
Is there a QR code format, barcode symbology, or encoding type we do not yet support? We welcome requests. Please describe your use case — whether it is for retail, events, signage, business cards, or another application — so we can understand the requirements and implement the tool correctly.
Business Inquiries
For advertising partnerships, content collaborations, or other business inquiries, please email [email protected] with "Business Inquiry" in the subject line.
