## Overview

The Mirror Image Extender allows you to increase your image canvas size by reflecting the existing edges, creating a seamless mirrored effect that is ideal for generating patterns, textures, and tiled backgrounds.

## Inputs

- **Image File** (file): Upload any image file (JPEG, PNG, WebP, TIFF, GIF, BMP)
- **Mirror Mode** (select): Choose how to mirror the image edges
- **Uniform Extension (pixels)** (number): Extension to add on all sides (recommended for seamless patterns)
- **Top Extension (pixels)** (number): Extension to add to the top edge
- **Right Extension (pixels)** (number): Extension to add to the right edge
- **Bottom Extension (pixels)** (number): Extension to add to the bottom edge
- **Left Extension (pixels)** (number): Extension to add to the left edge
- **Output Format** (select): Choose output format or keep original
- **Quality (1-100)** (number): Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

## When to use

- When you need to create seamless repeating patterns for web or print design.
- When you want to expand a background image to fit a specific aspect ratio without cropping or stretching.
- When you need to add padding to an image while maintaining visual continuity at the borders.

## How it works

- Upload your image file (JPEG, PNG, WebP, TIFF, GIF, or BMP).
- Select your preferred mirror mode and specify the extension size in pixels for each side.
- Adjust the output format and quality settings if needed.
- Download your newly extended image with the mirrored edges applied.

## Use cases

- Generating seamless textures for 3D modeling or game development.
- Creating custom desktop or mobile wallpapers from smaller source images.
- Preparing social media graphics that require specific dimensions without losing image content.

## Frequently asked questions

### What image formats are supported?

You can upload JPEG, PNG, WebP, TIFF, GIF, and BMP files.

### Can I add padding to only one side?

Yes, you can specify individual pixel values for the top, bottom, left, and right edges.

### What is the difference between Simple Mirror and Advanced Flip?

Simple Mirror uses standard edge reflection, while Advanced Flip provides a custom mirroring logic for different visual results.

### Is there a limit to how much I can extend the image?

You can add up to 1000 pixels of extension to any side.

### Will this tool change the original file format?

By default, it keeps the original format, but you can choose to convert the output to JPEG, PNG, or WebP.
