How to convert JPEG to JPG
JPEG and JPG are the same image format. The distinction is purely a file extension: JPEG is the full name (Joint Photographic Experts Group) while JPG is the three-character version used on older Windows systems where four-character extensions were not allowed. Any software that opens .jpg files also opens .jpeg files; only the extension differs, not the encoding.
If you need a .jpg extension instead of .jpeg (for example, because an upload form rejects .jpeg), this converter renames the file and optionally re-encodes it. The process is instant in your browser with no upload required.
Upload your JPEG file
Drop your .jpeg file into the drop zone. The file is read locally with no server upload.
Choose passthrough or re-encode
If you only need the extension changed, select passthrough mode. If you also want to adjust quality or dimensions, select re-encode and configure the settings.
Convert
For passthrough, the file is returned with a .jpg extension. For re-encode, the image is re-processed at the chosen quality.
Download the JPG

Frequently asked questions
Is JPEG and JPG the same format?
Yes, they are identical. The difference is only the file extension. Both store JPEG-compressed image data in the same way.
Does re-encoding JPEG to JPG lose quality?
If you simply rename the extension, there is zero quality loss. If you re-encode (decompress and re-compress), JPEG's lossy compression applies a second time, causing some additional quality loss.
Is my image uploaded to a server?
No. The operation runs in your browser. Your image stays on your device.
Why do some systems prefer .jpg over .jpeg?
Historical file systems on DOS and early Windows limited extensions to three characters. Many tools and scripts were written expecting .jpg and have not been updated to accept .jpeg.
Can I just rename the file myself?
Yes, for extension-only conversion, renaming the file in your OS file manager from .jpeg to .jpg is sufficient and produces identical results.
