File conversion is the process of changing a file from one format to another. This is often necessary when different software programs or devices require specific file types to function properly. For example, a document created in a Microsoft Word format may need to be converted to a PDF for easier sharing and printing. There are various tools and software available for file conversion, including online services and dedicated applications. These tools can handle a wide range of formats, such as converting JPEG images to PNG or MP3 audio files to WAV. Proper file conversion ensures compatibility and preserves the quality of the content.
