Convert JPEG to JPG
A form that accepts only .jpg rejects a .jpeg file, even though the picture is the same. Turn it into a .jpg in one click, and keep it under a KB limit if the form has one.

How to
How to convert JPEG to JPG
- 01
Add your .jpeg files
One photo or many. PNG, WebP and HEIC work too and come out as JPG.
- 02
Set a size limit if you need one
Leave it empty to keep the photo exactly as it is, or type the KB your form allows, for example 50.
- 03
Download the .jpg
Save each file, or all of them as a ZIP, and upload them to your form.
Why this size
JPEG and JPG are the same format
JPG is simply the three letter version of JPEG, from the days when Windows file extensions could only have three letters. The image inside is identical.
Some upload forms check the extension letter by letter, so a file ending in .jpeg is refused with a message like "only JPG allowed". When you add a JPEG here without a size limit, the tool keeps every byte of your photo and only gives it the .jpg name, so nothing is lost.

How the tool works
The image is decoded in your browser and saved again in the new format at a high quality setting. PNG and WebP keep transparent areas; JPG and GIF get a white background. A JPEG converted to JPG without a size limit keeps every byte and only changes the file name. Everything happens in your browser; your images are never uploaded.
