Whathefont saves your time from searching the font name. They scan the image and tells you list of possible font names. So I did a little experiment to test its efficiency. I came up with a image with font Eras Bold ITC (left) and upload to Whathefont to see it can tell the font name.
You might need to help fill up some alphabets ifsystem doesn’t understand them. Press search to continue.
Here’s the result I got, an Eras ITC, accurate!
