JPEG to JPG Converter

There is no difference in quality or format. JPG is simply the 3-letter extension used by older Windows systems. JPEG and JPG files are identical.

Some older systems, software, or websites only accept .jpg files. Converting ensures compatibility without any quality loss.

No. This tool simply renames the extension. Your image data remains exactly the same with no re-encoding.

Rename it — the two extensions describe the same format, so nothing inside the file has to change. On Windows, turn on View → Show → File name extensions first, otherwise you're only editing the visible part of the name and the .jpeg stays put. On macOS, rename in Finder and confirm "Use .jpg" when prompted. Use this tool instead when you have a batch to get through, or when you're on a phone where renaming isn't practical. What to avoid is re-saving through an image editor: that re-compresses the photo and costs quality for a change that only ever needed to touch the filename.

Early Windows versions (before Windows 95) required 3-character file extensions. This limitation led to .jpg becoming standard alongside .jpeg.
