To obtain a high-quality QR code, follow our recommendations.
Choose the size of the QR code depending on the location. For printing, use a larger size (300-500px)
Use a higher error correction level (H) for QR codes that may be corrupted
Make sure the colors have enough contrast for proper scanning
Test the QR code on different devices before use
A QR code (Quick Response code) is a two-dimensional barcode that can be scanned using a smartphone camera. QR codes are used to quickly exchange information: links, contacts, text, Wi-Fi passwords, etc.
To create a QR code, enter data (text, URL, email, phone, etc.), select size and settings, then click 'Generate'. The QR code will be created and ready for download.
The generator supports: text, URL, email, phone, SMS, Wi-Fi, vCard. Each type of data has its own format and is automatically processed when generating a QR code.
The size of the QR code depends on the location. For web pages: 200-300px, for print: 300-500px, for large posters: 500-1000px. The more data in the QR code, the larger the size should be.
The error correction level determines how resistant the QR code is to damage. Levels: L (7%), M (15%), Q (25%), H (30%). The higher the level, the more redundant information there is in the QR code.
Yes, you can choose a foreground color (usually black) and a background color (usually white). It is important to ensure sufficient contrast for proper scanning.
The QR code can be downloaded in PNG (raster image) and SVG (vector image) formats. PNG is suitable for web and print, SVG is suitable for scaling without loss of quality.
Select 'Wi-Fi' type, enter SSID (network name), password and security type (WPA, WPA2, etc.). The QR code will automatically connect to a Wi-Fi network when scanned.
Select 'Email' type and enter your email address. The QR code will automatically open the email client when scanned to send a letter to the specified address.
Select the 'Phone' type and enter the phone number. The QR code will automatically start a call when scanned on a device with telephone functionality.
Use the 'vCard' type and enter contact information: name, phone, email, address, etc. The QR code will automatically add the contact to your address book when scanned.
Our generator supports basic color customization. To add a logo, use special QR code editors or graphic programs after generation.
The maximum data size depends on the error correction level: L - up to 2953 characters (digits), M - up to 2331 characters, Q - up to 1663 characters, H - up to 1273 characters. For text: up to approximately 4296 characters (numbers) or 2953 characters (letters).
Possible reasons: insufficient color contrast, too small size, damaged QR code, low error correction level. Increase the size, use black and white colors, improve the error correction level.
A QR code can only contain one link. For several links, create several QR codes or use a special service that creates a page with a selection of links.
Select 'SMS' type, enter phone number and message text. The QR code will automatically open the SMS app when scanned.
QR codes themselves are safe, but you should be careful when scanning QR codes from unknown sources as they may contain malicious links. Check the URL before going.
The QR code cannot be edited - it is encoded data. To change, you need to create a new QR code with new data.
Download the QR code in PNG format with sufficient resolution (minimum 300 DPI for printing). Use a size of at least 2x2 cm for proper scanning.
Yes, you can choose any color for the foreground and background. It is important to ensure sufficient contrast (at least 70% is recommended) for proper scanning.
Error correction adds redundant information to the QR code, allowing data to be restored if it is partially damaged. Level H (30%) allows you to recover up to 30% of damaged data.
Yes, create a QR code with a URL that leads to the app download page on the App Store or Google Play. When scanning, the corresponding page will open.
Create a QR code with a URL to the payment page or use a special format for payments (for example, for some payment systems). The specific format depends on the payment system.
A regular QR code does not contain tracking functionality. To track, use URL short links with analytics or special services that create QR codes with tracking.
Create a QR code with a URL to the event page in your calendar or use the iCalendar (ICS) format. Many calendar services support automatic adding of events from QR codes.
Yes, use the 'Wi-Fi' type and enter the SSID, password and security type. The QR code will allow you to automatically connect to the network without entering a password.
Create a QR code with a URL to your social network profile (Facebook, Instagram, Twitter, etc.). When scanned, the corresponding profile page will open.
A QR code cannot directly contain a PDF file. Create a QR code with a URL for a PDF file posted on the Internet, or use cloud storage to host the file.
Use the 'vCard' type and enter all the necessary data: name, position, company, phone, email, address, website. The QR code will automatically add the contact to your address book.
Create a QR code with a URL on Google Maps or another map with coordinates. When scanning, a map with the specified location will open.
