## Overview

The Image Composite tool allows you to seamlessly merge multiple images into a single file with precise control over layout, blending, and output quality.

## Inputs

- **Base Image** (file): Base image that other images will be composited onto
- **Images to Composite** (file): Select 1-8 images to composite onto the base image
- **Layout Mode** (select): How to arrange the composited images
- **Blend Mode** (select): Blend mode for composited images
- **Canvas Width (px)** (number): Width of the final canvas (leave empty to use base image width)
- **Canvas Height (px)** (number): Height of the final canvas (leave empty to use base image height)
- **Background Color** (color): Background color for transparent areas (default: transparent)
- **Output Format** (select): Output format for the composited image
- **Quality (1-100)** (number): Output quality for lossy formats (JPEG, WebP, AVIF)

## When to use

- Creating multi-image collages or grids for social media or presentations.
- Applying creative blend modes to overlay textures or effects onto a base image.
- Standardizing the dimensions and format of multiple assets into a unified canvas.

## How it works

- Upload your primary base image and select up to 8 additional images to composite.
- Choose a layout mode such as grid, horizontal, or vertical to arrange your assets.
- Apply a blend mode and adjust canvas dimensions or background color as needed.
- Select your preferred output format and quality settings, then process the file.

## Use cases

- Generating product comparison sheets by merging multiple item photos into a single grid.
- Adding watermarks or decorative overlays to a series of images using specific blend modes.
- Creating consistent social media banners by combining background assets with foreground elements.

## Frequently asked questions
