Calculation Logic
JPEG and JPG are identical image formats. The double naming conventions stem from early FAT file systems that only supported three-letter extensions. This tool copies the binary blob dynamically and exports it under the .jpg suffix.
FAQ
Is there any loss in image quality?
None. Because the raw file data is copied directly without re-compression, this is a mathematically lossless change.
