Overview

The Gradient Image Extender allows you to expand your image canvas by adding custom linear or radial gradient backgrounds, perfect for creating modern design layouts, social media headers, or professional presentation assets.

When to use

When you need to add extra space around an image for text placement or design elements.
When you want to create a smooth, professional transition between an image and a background.
When you need to resize an image to specific dimensions while maintaining a clean, aesthetic backdrop.

How it works

1Upload your image file in any supported format like JPEG, PNG, or WebP.
2Select your preferred gradient type and define the start and end colors.
3Specify the extension padding for each side or use uniform padding to expand the canvas.
4Adjust the output format and quality settings, then process the image to download your result.

Use cases

Examples

Background

A vertical portrait photo needs to be converted into a wide banner for a blog header.

Problem

The image is too narrow and lacks the necessary space for overlaying text.

How to use

Upload the portrait image, set the left and right padding to 200 pixels each, and select a linear gradient that matches the brand colors.

gradientType: linear, startColor: #4f46e5, endColor: #818cf8, angle: 90, leftPadding: 200, rightPadding: 200

Outcome

A wide, professional banner with the original image centered and a smooth color transition on both sides.

2. Product Gallery Standardization

Background

Product photos have inconsistent dimensions, making the store gallery look unorganized.

Problem

Images need to be uniform in size without cropping the actual product.

How to use

Upload the product image and apply uniform padding to create a consistent canvas size with a subtle radial gradient background.
