Frequently Asked Questions

What is the difference between JPG and JPEG?
There is no difference in image quality or format. JPG and JPEG are the same JPEG image format. The .jpg extension exists because early Windows versions (DOS) limited file extensions to 3 characters. Modern systems support both .jpg and .jpeg extensions interchangeably.
Does converting JPG to JPEG lose quality?
No. This tool simply renames the file extension from .jpg to .jpeg without modifying any image data. The file content remains 100% identical — no re-encoding or compression occurs.
Why would I need to rename JPG to JPEG?
Some software, web platforms, or upload forms specifically require the .jpeg extension. Certain programming libraries or APIs may also expect .jpeg. This tool provides a quick way to batch rename files for compatibility.
Can I convert JPEG back to JPG?
Yes, you can simply rename the extension back. Since the file content is identical, switching between .jpg and .jpeg has no effect on the image itself.
Are my files safe?
Absolutely. All processing happens in your browser. Your images are never uploaded to any server. Once you close the page, all data is cleared.
