When to use?

Use it to quickly make background color samples, design dummy images, or test placeholder images.

How to use

  • Enter the width and height.
  • Choose a color.
  • Generate the PNG image.

Input Explanation

Enter the width and height in pixels and the background color (HEX or RGB).

Calculation Basis

It creates an HTML5 Canvas of the given size, fills the whole area with the single color, and converts it to a PNG Data URL.

Usage Examples

  • Make test images - Make a PNG of the specified color and size.
  • Prepare images for upload - Preview the result, then tidy images for blogs, shops, or social media.
  • Compare results - Check original and result side by side for quality and display.

Examples

  • Width 800, height 600, color #3498db → an 800×600 blue background image
  • A 1920×1080 solid image → a backing board for a slide

Cautions

  • It processes via browser canvas, so original metadata (EXIF) may be lost or transparent areas may change color.
  • Extremely high-resolution large files may fail to convert due to browser image-decoding limits.
