How to convert JPG to JPEG
JPG and JPEG refer to the exact same image format and encoding. The only difference is the file extension: .jpg is the three-character variant that became standard on older Windows systems, while .jpeg is the full original extension. If a system, tool, or upload field insists on .jpeg and you have a .jpg file, the simplest fix is renaming the extension, which changes nothing about the image data.
This converter handles the extension change and optionally re-encodes the image if you want to adjust quality or dimensions at the same time. Processing runs in your browser with no upload needed.
Upload your JPG file
Drop your .jpg file into the drop zone. The file is read locally.
Choose passthrough or re-encode
For extension-only change, select passthrough. For quality or size adjustments, select re-encode.
Convert
The file is returned with a .jpeg extension, with or without re-encoding based on your selection.
Download the JPEG
Click Download to save the .jpeg file.
Frequently asked questions
Are JPG and JPEG different formats?
No. They are the same format. The encoding is identical; only the file extension differs.
Can I just rename the file myself?
Yes. Changing the extension from .jpg to .jpeg in your file manager has the same effect. No conversion is needed.
Will renaming lose quality?
No. Renaming does not touch the image data. Quality loss only happens if you re-encode (decompress and re-compress) the file.
Is my image uploaded to a server?
No. Everything runs in your browser.
Why would a system require .jpeg instead of .jpg?
Older software or strict upload validators may check the extension character-for-character. This is a quirk of the specific system rather than a technical requirement.
