Apply the gradient left-to-right, top-to-bottom, or as a radial burst from the center — one click to switch between them.
🔆
0–100 Opacity

How to Add a Gradient to an Image

The tool blends between two endpoint colors and overlays the entire image canvas. Choose a direction and set opacity to control how much of the original image remains visible. There is no selection or mask for limiting the effect to one region.

  1. Upload an image. Choose the photo or graphic you want to edit.
  2. Set the gradient. Choose two colors, select horizontal, vertical, or radial direction, and adjust opacity.
  3. Apply and review. At 0 opacity the overlay is invisible; at 100 it can cover the source image. Download when the blend looks right.

Common Questions

Does the gradient affect the whole image or just a selection?

It overlays the full canvas. There is no selection or mask control in this tool.

What is the difference between the gradient directions?

Horizontal blends from side to side, vertical blends from top to bottom, and radial blends outward from the center.

How does opacity affect my photo?

At 0 opacity the gradient is not visible. Increasing opacity makes it more prominent; at 100 it can completely cover the source image.

Can I use more than two gradient colors?

This tool has two color controls for the gradient endpoints. For gradients with extra color stops, use an editor that supports multi-stop gradients.

Choose Gradient Direction and Blend Strength

Use horizontal for a side-to-side transition, vertical for a top-to-bottom transition, or radial for color spreading outward from the center. The tool uses two endpoint colors and applies the blend across the full canvas.

For a photo overlay: begin at a lower opacity and increase it gradually. At 100 opacity the gradient can hide the image beneath it, so review the details and any text before downloading.

If only part of the image should change, use an editor with selections or masks; this tool does not limit the gradient to a selected area.
