PNG image gradient generator

Create gradient backgrounds and export PNG with custom colors, size, angle, zoom, and transparency. Generate image gradients in your browser.

What is an image gradient generator?

An image gradient generator creates a rendered bitmap from color stops and direction settings. This tool focuses on linear PNG gradients with configurable dimensions, angle, zoom, and optional alpha at each stop. Use it when you need to create a gradient background file for design, social, or UI mockups instead of CSS-only code.

Image gradient generator features

Key controls to create gradient backgrounds and PNG image gradients.

  • Two-color gradient

    Choose start and end colors with picker or hex input.

  • Custom dimensions

    Set output width and height in pixels.

  • Transparency controls

    Optional alpha for each color stop.

  • Orientation and zoom

    Rotate and scale gradient transition.

  • Live preview

    Gradient updates immediately as options change.

  • PNG download

    Export the generated gradient as PNG.

How to create a gradient background

Generate a gradient background image in four quick steps.

  1. Choose colors

    Set first and second gradient colors.

  2. Set image size

    Define output width and height in pixels.

  3. Tune gradient

    Adjust transparency, orientation, and zoom.

  4. Download PNG

    Save the generated gradient image file.

Tips for better gradients

Practical guidance for clean output.
  • 01

    Use larger canvas for print

    Set high pixel dimensions before download.

  • 02

    Keep contrast balanced

    Mid-tone pairings usually look smoother than extremes.

  • 03

    Test orientation presets

    0, 45, 90, 135 degrees are good starting points.
