Now you know what features to look out for while finding a quick QR Code generator. Let us help you find one.
To find it, you will run a quick query on a search engine. And it will give you many options to choose from. But going through each one of them will consume a lot of your time.
Don’t worry. You don’t really need to do that. Here is a detailed comparison chart of the top QR Code API service providers. You can go through it to decide the best one for your use case.
In case you are short on time, here is one tool that can help you offer all the above—QR Code API.
It allows you to create QR Codes programmatically in real-time within your information system or mobile app. Here, your application or information system will send an API request to QR API. In return, you’ll get the required QR Code in real-time in your app or information system.
Hence, QR Codes will be generated within seconds of sending the request. Isn’t that amazing? And the best part is you don’t need to do any manual work each time you need to generate QR Codes.

The eyes are the big squares at the corners of the QR Code. They help scanners recognize the QR Code. You can customize them as per your wish. That means you can change both the color and pattern of the eyes.
2. Data modules
Data modules are small square-shaped elements across the QR Code. They store the information you encode in the QR Code. These modules can be customized by changing their patterns or adding a color to them.
In addition, QR Code API also allows you to add a gradient to the color of data modules.
A logo is situated at the center of the QR Code. It could be an image such as your company or brand’s logo.
4. Error correction
If you add a logo to your QR Code, some data modules near the center will be removed. It is done so to accommodate the logo image.
This removal of data modules introduces an error in the QR Code. So, to ensure QR Code’s high scannability, you need to have an appropriate level of error correction. Error correction ensures that the QR Code can scan well even after the addition of a logo. Here are the different error-correction levels:
- L (7%)
- M (15%)
- Q (25%)
- H (30%)
5. Background Color

For example, if the color of the QR Code is black, the background must be white in color and vice-versa.
In addition to the custom-logo design, you can also use the Poster option to customize the QR Code. Here, you can add a background image to your QR Code. Moreover, you can also change the pattern of both the eyes and data modules.
