What is file format conversion?
File format conversion is the process of changing a file from one format to another to ensure compatibility with software, systems, or devices, while keeping the structural content of the file intact.
Converting the file format is necessary when the original JPEG format is not supported by the software or device you want to use. This capability allows users to make use of JPEG files in various formats, ensuring compatibility and facilitating seamless information sharing between platforms.
For file format conversion, dedicated programs or online tools are designed to meet this need. These tools come with a simple interface that helps users choose the input JPEG file, set the JP2 format, and begin conversion.
