Yes, we offer completely free static QR code generation. You can create unlimited static QR codes including URL, text, email types without registration or payment.
Static QR codes never expire. Once generated, they work forever. However, if the content your QR code points to (like a website) changes or becomes unavailable, the QR code may not work properly.
Creating a QR code for restaurant menus is simple: 1. Prepare your menu (PDF format or webpage link) 2. Choose the appropriate QR code type (PDF or URL) 3. Upload file or enter link 4. Customize design 5. Download and print
Static QR codes cannot be changed once generated. If you need to modify the link, you need to generate a new QR code. For editable QR codes, we recommend using dynamic QR codes (requires account registration).
You can customize your QR code in many ways: change colors, add logos, select different style templates, adjust sizes, etc. All these options are available in the design step of the generation process.
For printing purposes, the minimum recommended size is 2x2 cm. For digital displays, at least 150x150 pixels. The specific size depends on scanning distance and usage.
Our free version currently supports single QR code generation. If you need bulk generation, please contact us about enterprise solutions.
We support multiple formats: images (PNG, JPG, SVG), documents (PDF), video and audio files, etc. Generated QR codes can be downloaded as PNG, JPG or SVG formats.
If your QR code cannot be scanned, please check the following: 1. Ensure the QR code is clear and not blurry or damaged 2. Check contrast - we recommend dark foreground on light background 3. Make sure the QR code is large enough 4. Avoid adding too many decorations that may affect scanning
After registering and logging in, you can view detailed scan statistics for each dynamic QR code, including scan count, time, geographic location, device type, and more to help you understand QR code usage.
When printing QR codes, please note: 1. Use high-quality print settings 2. Ensure sufficient contrast 3. Avoid excessive image compression 4. Test print results to ensure scannability 5. Leave adequate quiet zone around the code
Enterprise plan users can use the bulk generation feature to create multiple QR codes at once by uploading a CSV file, greatly improving work efficiency. Contact our sales team for more details.
When adding a logo, we recommend: 1. Logo size should not exceed 30% of the QR code 2. Ensure the logo doesn't cover critical positioning points 3. Use PNG format with transparent background 4. Always test scanning after generation
Dynamic QR codes are codes whose content can be changed. Unlike static QR codes, dynamic QR codes store a short link that you can change the target address anytime without regenerating or reprinting the QR code.
Yes, you can fully customize QR code colors. You can choose foreground and background colors, but ensure there is sufficient contrast between them for successful scanning. We recommend dark foreground on light background combinations.
To create a vCard QR code: 1. Select vCard type 2. Fill in your contact information (name, phone, email, company, etc.) 3. Customize the design 4. Generate and download. Scanning this QR code will automatically add contact info to the phone's address book.
To create a WiFi connection QR code: 1. Select WiFi type 2. Enter network name (SSID) 3. Select encryption type (WPA/WPA2/WEP) 4. Enter password 5. Generate QR code. After scanning, users can connect to the WiFi network directly without manually entering the password.
We use enterprise-grade security measures to protect your data and QR codes. Static QR codes directly encode your data and are not stored on our servers. Dynamic QR codes use encrypted connections to ensure secure data transmission.
Yes, Enterprise plan users can access our API to integrate QR code generation into your own applications or systems. The API supports multiple programming languages with complete documentation and technical support.
Currently, we offer a mobile-friendly web version accessible from any mobile browser. We are developing native mobile applications - stay tuned!
