Convert JPEG to JPG
JPEG and JPG are the same format with two spellings. This page changes the extension to .jpg and leaves the picture itself untouched, so nothing is lost.

How to use the jpeg to jpg converter
Add your .jpeg files and download them as .jpg. JPEG and JPG are the same format, so this page does not convert anything: it copies each file byte for byte and changes only the extension, which means no quality is lost.
- Add your .jpeg filesUp to 20 at a time. Files ending in .jpe or .jfif work too.
- Nothing to setThere is no quality setting, because the picture is not saved again.
- Download the .jpg filesOne by one, or together as a ZIP.
About this tool
The format is called JPEG. Early versions of Windows allowed only three letters in a file extension, so .jpeg was shortened to .jpg, and both spellings have been in use ever since. The bytes inside are the same either way.
The difference only matters when something checks the name. Some upload forms and older programs accept .jpg and refuse .jpeg. Converters that handle this by saving the picture again re-compress it and lose a little quality for no reason. This page copies the file as it is and changes only its extension.
What you get
- Changes .jpeg, .jpe and .jfif to .jpg
- No re-compression: the image data is copied byte for byte
- Checks that each file really is a JPEG first
- Keeps EXIF data, because nothing is rewritten
- Batch up to 20 files with ZIP download
When to use the jpeg to jpg converter
Upload forms that only list .jpg
A form whose file check looks at the extension will refuse photo.jpeg and accept the identical photo.jpg.
Older programs and devices
Some photo frames, printers and legacy applications look for three-letter extensions and skip anything else.
Keeping file names consistent
A folder that mixes both spellings sorts and filters awkwardly. Bring every file to .jpg in one pass.
Scripts and templates that expect .jpg
Web templates and import tools often build file names with a fixed .jpg ending.
Changing the extension compared with re-saving
| Aspect | This page | Re-saving as JPG |
|---|---|---|
| Image quality | Identical to the original | Slightly lower each time |
| File size | Unchanged | Changes with the quality setting |
| EXIF metadata | Kept | Usually removed |
| Speed | Instant, at any resolution | Depends on the pixel count |
| What changes | Only the extension | Every pixel is re-encoded |
How it works
A file's extension is a label, not part of its contents. What makes a file a JPEG is how its bytes begin: the first two are always FF D8, followed by a marker that introduces the first segment. This page reads those bytes to confirm the file is a JPEG, then hands back exactly the same data under a name ending in .jpg. Nothing in between is decoded.
That is different from how most online converters treat this job. They open the picture, draw it and save it again, which runs it through JPEG compression a second time. Each pass rounds the image data off a little more, so a file converted that way is never quite as good as the one it came from. Since the two extensions mean the same format, there is no reason to pay that cost.
Common problems and how to fix them
- It says my file is not a JPEG
- The file has a .jpeg or .jpg name but different contents, often a PNG or WebP that was renamed. Use the Image to JPG Converter, which re-encodes it properly.
- It says there is nothing to change
- The file already ends in .jpg, so the copy you download is the same file under the same name.
- The upload form still rejects the .jpg
- Then the extension was not the problem. Check the form's limits on file size and pixel dimensions; the Image File Size Reducer can bring the file under a size limit.
- I wanted a smaller file
- This page does not compress. The file is the same size before and after. Use the JPG Compressor to reduce it.
Frequently asked questions
Is there a difference between JPEG and JPG?
No. They are two extensions for the same format. The shorter one exists because early Windows limited extensions to three letters. Any program that opens one opens the other.
Does converting JPEG to JPG lose quality?
Not here. The file is copied byte for byte and only the extension changes. Converters that save the image again do lose a little quality each time, which is why this page does not work that way.
Why does a website reject my .jpeg file?
Its upload check looks at the extension and only lists .jpg. The file itself is fine. Change the extension here and upload the .jpg copy.
Is the metadata kept?
Yes. Because nothing is re-encoded, EXIF data such as the date, camera and location stays in the file. To remove it, use the EXIF Remover.
How do I change JPEG to JPG?
Add the .jpeg file above and download the .jpg copy. You can also rename the file yourself, because the format is the same; this page is quicker for a batch.
Can I convert several .jpeg files at once?
Yes. Add up to 20 files, press "Process all images" and download them together as a ZIP.
Can it convert JPG back to JPEG?
No, this page only writes .jpg. The two are the same format, so renaming the file by hand to .jpeg works if something insists on the longer spelling.
