JPG and JPEG are the same format

JPG and JPEG are identical image formats. The only difference is the file extension. Early Windows systems limited extensions to 3 characters, creating ".jpg". Modern systems support ".jpeg". This tool renames the extension without modifying image data.

Frequently Asked Questions

What is the difference between JPG and JPEG?
There is no difference in image quality or format. JPG and JPEG refer to the exact same thing. The .jpg extension started because older Windows versions (like DOS) couldn't handle more than 3 letters in a file extension. Nowadays, systems support both .jpg and .jpeg easily.
Does converting JPG to JPEG lose quality?
No worries, it won't. This tool simply changes the file name ending from .jpg to .jpeg without touching the actual image data. The file content stays 100% identical — absolutely no re-encoding or compression happens.
Why would I need to rename JPG to JPEG?
Some specific software, web platforms, or upload forms (often used by Aussie businesses) might strictly require the .jpeg extension. It's also common for certain programming libraries. This tool gives you a quick way to batch rename files to get things moving.
Can I convert JPEG back to JPG?
Yeah, you can just change the extension back. Since the file inside is exactly the same, switching between .jpg and .jpeg doesn't affect the image at all.
Are my files safe?
Absolutely. All processing happens locally in your browser on your device in Sydney, Melbourne, or wherever you are. Your photos are never uploaded to a server. Once you close the tab, all data is cleared from memory.
