JPEGJPGJPEG to JPG Converter
Here is the thing nobody selling you a converter will say: JPEG and JPG are the same file format. The extension is different because Windows once allowed only three letters. PhotoTray checks that your file really is a JPEG, then renames it — instantly, with the image untouched. Every online converter decodes and re-encodes it, which makes your photo very slightly worse to accomplish nothing.
Drop in your files — Same file, new extension — no re-encoding, so no quality loss at all.
Why convert
Why convert JPEG to JPG
Almost always because a form, a piece of software, or a person has asked for a .jpg and you have a .jpeg. The file is already correct; only its name disagrees. Some upload validators check the extension text rather than reading the file, which is a bug in their software that you nonetheless have to work around.
- An upload form that only accepts .jpg and rejects .jpeg outright.
- Software or a script that matches on the file extension.
- Making a folder of mixed .jpg and .jpeg files consistent.
- A submission guideline that names .jpg specifically.
How it works
Convert JPEG to JPG in a few clicks
- 1
Drop your JPEG files in
One file or an entire folder of them.
- 2
PhotoTray checks the file header
It reads the first bytes to confirm the file genuinely is a JPEG, rather than trusting the extension. A mislabelled PNG would otherwise end up with a name that lies about its contents.
- 3
It renames, and stops
No decoding, no re-encoding, no quality loss, no waiting. The bytes of the image are identical to what you started with.
