JPG vs JPEG – What's the Difference?
Many users wonder whether JPG and JPEG are different image formats. In reality, they are exactly the same.
The only difference is the file extension. Earlier versions of Windows supported only three-character file extensions, so .jpegbecame .jpg. Both extensions use the same compression method, provide identical image quality, and are fully compatible with modern devices, browsers, and image editing software.
Whether your image ends with .jpg or .jpeg, CompressJPEGs compresses it using the same high-quality optimization process.
