Quick answer
JPEG and JPG are the same image format; only the file extension differs. FreeImageKit changes .jpeg, .jfif and .jpe files to .jpg for free, in your browser, without uploading them. Each file is copied byte for byte, so the pixels, quality, file size and metadata stay exactly the same, and a batch downloads as one ZIP. Use it when a form or app only accepts files ending in .jpg.
How to use this tool
- Select one or more JPEG, JFIF or JPE files.
- Check the new .jpg names in the list.
- Rename to JPG and download the file, or a ZIP for a batch.
Batch-ready
Use the same settings for several files, then download them separately or in a ZIP.
Frequently asked questions
Is JPEG the same as JPG?
Yes. Both names refer to the same JPEG format. Early Windows versions limited extensions to three letters, so .jpg became common; .jpeg, .jpe and .jfif files hold the same kind of data.
Does converting JPEG to JPG reduce quality?
Not here. The file is not decoded or re-encoded; only the extension changes, so the image is identical to the original.
Can I just rename the file myself?
Yes, renaming the extension on your computer does the same thing. This tool is quicker for a batch, works on phones where extensions are hidden, and checks that each file really is a JPEG.
What if my file is not really a JPEG?
The tool checks each file's contents. A PNG, HEIC or WebP saved with a .jpeg name is refused with a note to use Convert Image, which re-encodes it as a real JPG.
