How to use Convert JPG to JPEG
- 1. Upload the .jpg file. Drop or browse for the .jpg file whose extension needs to change. It loads into the preview so you can confirm it is the correct file.
- 2. There is nothing to configure. JPG and JPEG are the same image format under two different file extensions, so no compression, resizing or quality settings apply. The image data itself does not change at all.
- 3. Download the .jpeg file. The tool renames the file's extension to .jpeg while keeping every byte of image data identical. Download it wherever a .jpeg extension is specifically expected.
When to use Convert JPG to JPEG
Convert JPG to JPEG simply renames a .jpg file to use the .jpeg extension. The underlying image data is byte-for-byte the same, since JPG and JPEG describe the exact same format, so this is purely a filename fix rather than a real conversion.
- Meeting a strict upload form's extension check. A form's validation only accepts files ending in .jpeg and rejects .jpg outright; renaming the extension gets the same image through the upload without any loss.
- Matching a naming convention across a project. A team's asset pipeline standardizes on the .jpeg extension for consistency; existing .jpg files get renamed in bulk to match that convention.
- Satisfying a script that filters by extension. An automation script only picks up files matching *.jpeg, so a batch of .jpg photos needs the extension changed before the script will process them.
- Clarifying file type for a less technical recipient. A recipient's software only recognizes files it sees as .jpeg; renaming a .jpg photo avoids confusion without altering the actual image at all.

About the Convert JPG to JPEG tool
Convert JPG to JPEG runs as plain JavaScript in your browser tab, with no server behind it. Rename .jpg files to .jpeg: the data is identical, only the extension changes. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JPG Tools section, 145 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
