How to Use the Online Coloring Tool
01Pick a Page & Colors
Choose from our free coloring page templates or upload your own. Select from 30+ preset colors or create a custom shade.
02Click or Tap to Fill
Simply click any white area on the coloring page and it fills instantly with your selected color. It's like a magic paint bucket.
03Save & Download
Finished? Download your artwork as a high-resolution PNG. Print it, share it online, or start a fresh page.
Getting Clean, Spill-Free Fills Every Time
Click-to-fill works best with clean, bold outlines — thin or broken lines can let color spill into neighboring areas. If that happens, just pick white and click the spilled area to clean it up. For shading effects, try filling the same area 2-3 times with progressively darker shades. The Bucket Fill detector respects fully closed outlines, so make sure your line art has no gaps for the cleanest fill.
