How to change JPEG to JPG
- Add your JPEG filesChoose .jpeg files, drop them on the box or paste an image. Each file is converted the moment it is added.
- Leave the defaults aloneThe picture data is copied as it is, so the new .jpg is the same image. Tick Re-encode only if you want to pick a quality, or Keep metadata to retain camera details.
- Download the JPG filesSave a single file, or press Download all (ZIP) to get every renamed file in one go.
Is JPEG the same as JPG?
Yes. JPEG and JPG are the same image format. The name comes from the Joint Photographic Experts Group, who defined it. The short .jpg spelling appeared because older Windows systems only allowed three-letter extensions, and it stuck. Inside the file nothing differs, which also answers the reverse search: a JPG is a JPEG, so "jpg to jpeg" is just a rename too.
That is why this conversion is lossless. There is no new format to encode, only a different name. The tool copies the compressed picture into a new .jpg file without decoding it.

Does changing JPEG to JPG lose quality?
No. We checked it on this tool: a 12 megapixel .jpeg and a small one went in, and the downloaded .jpg files were exactly the same size as the originals, with matching SHA-256 hashes. Identical bytes means an identical picture, with no second round of compression.
| Input | Input size | Downloaded JPG | Same bytes? |
|---|---|---|---|
| photo-12mp.jpeg, 4032 x 3024 px | 2,179,008 bytes | 2,179,008 bytes | Yes, hashes match |
| sample.jpeg, 1200 x 800 px | 59,035 bytes | 59,035 bytes | Yes, hashes match |
The photo-like image is our own sample scene scaled to 12 MP with seeded camera-like noise. These test files carry no EXIF block. A camera photo with one comes out a little smaller, because EXIF is removed unless Keep metadata is ticked. If you tick Re-encode, the picture is saved again and the size changes.
When does the extension matter?
Mostly for software that is strict about names. Some upload forms, content systems, print shops and older programs accept .jpg but reject .jpeg, or the other way round. Renaming by hand is tedious when you have dozens of files, and a batch converter does it in a click.
It also helps with consistency. If a website has photo.jpeg and photo.jpg in different places, search and link checks treat them as separate files. Settling on one extension avoids that. Case matters on some servers too, so the output is always lowercase .jpg.
- Need .jpeg instead? A JPG is already a JPEG, so rename the file yourself. No conversion step is needed.
- A file that only looks like a JPEG but is really a PNG, WebP or HEIC image cannot be fixed by renaming. The tool reads the content, not the name, and tells you what it found.
- Files that end in .jfif or .jpe are JPEG too. The JFIF page covers files that will not open in your apps.
Metadata, rotation and batches
Unless Keep metadata is ticked, EXIF, XMP and comment blocks are removed, so location and camera details do not travel with the new file. Color profiles stay, so colors do not shift. A photo that is shown upright only because of an orientation flag would turn sideways without that flag, so in that one case it is re-encoded upright and the file row says so.
You can add up to 30 files at once on a computer and 15 on a phone, each up to 50 MB on a computer and 30 MB on a phone, and download them as a ZIP.
Questions
Is JPEG the same as JPG?
Yes. They are the same format. The .jpg spelling exists because older Windows versions limited extensions to three letters.
How do I change JPEG to JPG?
Add your .jpeg files to the box on this page and download the .jpg results. The picture is copied unchanged, so it takes a moment even for large files.
Does changing JPEG to JPG reduce quality?
No. By default the compressed image data is copied without decoding, so the pixels stay exactly the same.
How do I change JPG to JPEG?
Rename the file so it ends in .jpeg. Because the two are the same format, nothing else needs to change, which is why this site has no separate converter for it.
When should I rename JPEG to JPG?
When a form, app or print service rejects .jpeg, or when you want one consistent extension across a website or a folder of photos.
What if my file is not really a JPEG?
Renaming does not convert formats. The tool checks the file content and shows a message if it is a PNG, WebP, HEIC or something else, so you can use the matching converter.
Are my files uploaded?
No. Everything runs in your browser and no file leaves your device.
