    The preview is scaled to fit. Your download uses the exact pixel dimensions above.

    CSS and PNG may render slightly differently because browsers handle color interpolation differently.

    How to use

    1. Set the image dimensions and select a linear or radial gradient.
    2. Choose the start and end colors, optionally add a middle color, and adjust the linear angle.
    3. Download the PNG or JPEG, or copy the CSS background declaration.

    What to keep in mind

    This creates decorative gradient backgrounds. To inspect banding, use the separate gradient test. A generated image cannot certify your display’s bit depth or color accuracy.

    Questions

    What does the gradient angle mean?

    Angles follow CSS conventions: 0° moves from bottom to top, 90° from left to right, and 180° from top to bottom. Radial gradients start at the center.

    Will the downloaded gradient match the CSS exactly?

    They use the same colors and direction, but browser color interpolation and image scaling can produce small differences. Use the downloaded image when a fixed pixel result matters.
