Here is what happened the other day. My daughter asked me to find a Pokemon Eevee Evolving coloring page for her to sharpen her coloring skill. And she found this and was wondering if I had any magic to turn it into a coloring page that she can use.
After failing to find an alternative real coloring page version of this picture online, I ended up doing some research and found three ways to convert any picture into a coloring page.
There are two web apps that work quite well.
Lunapic is basically a free online photo editing web app that includes a feature that lets you make coloring books. Simply upload a picture, and it turns it into a coloring page right after.
ScrapColoring also has an online tool that converts your drawings and photos to coloring pages. All you need to do is to upload a picture, and it will be automatically and instantly into shapes that can be colored. Once converted, you can click the Print button to print a copy or the Disk icon to save the result to your local computer.
If you have a decent photo editing tool installed on your PC like PhotoShop, you are already capable of doing so out of the box. If not but still would like to use a desktop app to do the work, Pixlr is a pretty good choice that is free and can get the job done. And if you do, here is a very detailed instruction that you can follow.
What I ended up using is actually a mobile app called Colorscape and successfully converted the colorful Eevee evolving picture to a coloring page my daughter eventually enjoyed coloring.
However, I couldn’t find a similar one in Google Play that can do a job as good as Colorscape.
