JPEG and JPG are the same format
The two extensions describe identical files. Early versions of Windows only allowed three letter extensions, so .jpeg was shortened to .jpg, while Mac and Linux kept the longer spelling. Cameras and phones still use either one.
Why change JPEG to JPG
Some upload forms, content systems and older programs check for .jpg exactly and reject a .jpeg file even though nothing is wrong with it. This page copies each image byte for byte and saves it with the .jpg extension, so there is no recompression and no quality change at all.
How to convert JPEG to JPG
- Drop your .jpeg files onto the box above. Batches are fine.
- Press Convert to JPG to rename them without touching the image data.
- Download each JPG or all of them in one zip.
Nothing is uploaded. The conversion runs inside your own browser, so your files never touch a server and there is no queue, no size cap and no sign up.
JPEG to JPG questions
Is there any quality loss going from JPEG to JPG?
None. The file contents are copied unchanged, only the name changes.
Is JPG better than JPEG?
Neither is better. They are two spellings for exactly the same format.
Does it keep the photo date and camera details?
Yes. Because the bytes are copied as they are, any metadata inside the JPEG stays in the JPG.
