## Overview

File Converter is an open-source Windows application created by Adrien Allard (Tichau) that allows you to convert and compress one or multiple files directly from the Windows File Explorer context menu. 

For static website creators, it provides a fast offline workflow to batch-convert images (PNG, JPEG, TIFF, BMP) into lightweight modern web formats such as **WebP** or **ICO**, as well as compress assets before committing them to Git—all without opening graphic design software or uploading files to an online service.

> [!NOTE]
> **Windows 11 Usage Note**:  
> Because Windows 11 uses a streamlined right-click menu, File Converter appears under the classic context menu. To access it on Windows 11:
> 1. Right-click the file(s) in Windows File Explorer.
> 2. Click **Show more options** (or press `Shift` + `F10`).
> 3. Hover over **File Converter** in the menu and select your target format (e.g., *To Webp*, *To Png*).
