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.

  1. Two-color gradient: Choose start and end colors with picker or hex input.
  2. Custom dimensions: Set output width and height in pixels.
  3. Transparency controls: Optional alpha for each color stop.
  4. Orientation and zoom: Rotate and scale gradient transition.
  5. Live preview: Gradient updates immediately as options change.
  6. 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.

  1. Use larger canvas for print: Set high pixel dimensions before download.
  2. Keep contrast balanced: Mid-tone pairings usually look smoother than extremes.
  3. Test orientation presets: 0, 45, 90, 135 degrees are good starting points.

Great for

Typical linear gradient image use cases.

  1. Background assets: Hero sections, cards, and app screens.
  2. Social graphics: Story backdrops and promo templates.
  3. UI prototyping: Quick placeholder backgrounds with precise sizing.

Why use this tool

Quick client-side gradient image generation.

  1. No upload required: Everything renders locally in browser.
  2. Fast adjustments: Real-time preview for angle and color tuning.
  3. Exact dimensions: Output assets in required pixel size.
  4. Free PNG export: Download and reuse in any design workflow.
