To become a readable QR code, please remember that your QR color should be highly contrasted with the background. Please see this example:

You can test the adjustment of your color in the QR color picker. You should scan the colored QR code with your phone camera (QR code scanner). If your camera detected the QR with a text "Yes! let's go!" than your QR code will be fine.

This guide is only explaining about readable QR code with customized color. The length of encoded URL also takes part in our QR code generator. Please see the requirements of the URL length.
Inserting your brand logo or preferred picture is important if you need to share to your business colleagues. We provide you this kind of possibility by inserting your Logo/Picture into your QR Code (click customize first, under the Original URL form-field).

HOWEVER, we suggest you that your image should be readable, square image, 24bit PNG/JPEG image and no greater than 600x600 pixels.

If you does not meet the requirements the system might be still processing your image or for the worst scenario, it will assume that your QR code has no logo like when you are emptying the logo form-field. Also, the bigger your images size, the longer time of QR code creation will be done.

We are prohibiting user to upload images to our server. As the solution, you should insert your pre-uploaded image URL. If you do not have uploaded image, we simply recommend you to upload your image to free image hosting like tinypic.

Just click the Upload link and follow these instructions:
1. Open tinypic. Choose file and then push UPLOAD NOW button.
2. (if available) Wait the Captcha process then insert it.
4. Copy the image link in "Direct Link for Layouts".
5. Paste the link in LOGO form-field.

Even though we use High EC LEVEL, we are afraid that your generated QR Code will be difficult to read (scan). The lenght of your URL is affecting the density of your QR Code. It will be very dense with small squares and dots if you put very long URL.

For instance we have this URL: click to show

Then the QR Code will be very dense like this result:

So, it is not recommended to share that kind of QR Code. It is hardly difficult to be read if it is attached into small media like flyer or booklet.
