Category: Image Tools

When to use?

Use it to quickly make a gradient image for a banner, thumbnail background, or design mockup.

How to use

  • Enter the size and direction.
  • Choose the start and end colors.
  • Generate the PNG image.

Input Explanation

Set the width/height in pixels, the gradient direction (horizontal, vertical, diagonal), and the start and end colors.

Calculation Basis

It uses the Canvas createLinearGradient with the set direction and color stops to render a linear gradient image and return it as PNG.

Usage Examples

  • Make background images - Make horizontal, vertical, or diagonal gradient images.
  • 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

  • Diagonal, start #ff7eb3, end #ff758c → a soft pink diagonal gradient image
  • Vertical, purple→blue → a mobile app splash background

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.
