If the characters are connected to each other, it is impossible to identify.There are two ways to deal with it:

First, you can Through the "crop" function, the clippings of the part of the cut and then identify, drag the frame to the appropriate location, and then click "OK" button.

Second, you can adjust the threshold value until the characters are not connected.

Tip: Threshold Value

Threshold value is critical value, that is the division between black and white.When the value is higher than 128, it will turn into white and when the value is lower than 128, it will turn into black.If you upload a gray picture or colorful picture, LikeFont will turn it into a black and white picture automatically and you can set a grey threshold value if necessary.

Third, you can erase the connection with photo editor before you upload the image.
