Changing file extensions from .jpeg to .jpg involves modifying the suffix of filenames. The terms .jpeg and .jpg represent identical image file formats (JPEG compression); they function exactly the same way. This change only alters the filename text itself and does not convert the image data format.

You can achieve this renaming manually by selecting individual files and editing the extension one by one in your computer's file explorer. For batch processing an entire folder, use your operating system's built-in tools or dedicated software. For instance, on Windows, you can use Command Prompt (ren *.jpeg *.jpg) or File Explorer's batch rename feature. On macOS, use the Batch Rename function in Finder or Terminal commands. Third-party tools like Adobe Bridge or free utilities like Advanced Renamer also offer this capability.

The primary advantage is consistency in naming conventions across projects or systems. Since .jpeg and .jpg files are functionally identical, this renaming carries almost no risk of corruption. The limitation is that it only modifies the filename suffix; it does not alter the actual image quality or compression settings. Care should be taken to only rename actual JPEG image files, as incorrectly changing the extension of a different file type can make it unreadable. Future developments in file management tools will likely make bulk renaming even more seamless.
