Frequently Asked Questions
Are your coloring pages really free?
Yes! All our coloring pages are 100% free to download and print. There are no hidden costs, subscriptions, or limitations. You can download as many pages as you like.
Can I use these coloring pages in my classroom?
Absolutely! Our coloring pages are perfect for educational use. Teachers are welcome to print and distribute them to students. We only ask that you do not sell or redistribute our pages commercially.
Can I request new coloring pages?
We are always looking to expand our collection. If you have suggestions for new coloring pages or categories, please email us and we will consider adding them to our library.
How do I print the coloring pages?
Simply click the download button on any coloring page to open the full-resolution image. Then right-click and save the image to your device. You can print it directly from your computer or take it to a local print shop.
What is the best paper to use?
For best results, we recommend using white cardstock or heavy-weight paper. However, standard printer paper works well for most coloring activities. If using markers, consider using thicker paper to prevent bleed-through.
