Drop in .jfif files and get .jpg files that upload forms and apps accept. They're already JPEGs, so nothing is re-encoded and the picture doesn't change.

Runs in your browser. Nothing is uploaded.

## How to use it

1. **Add JFIF files.** Drop one or several.
2. **Check the list.** Each file is marked as kept as it was: same picture, same size.
3. **Download.** Save a single JPG, or all of them in one ZIP.

## A JFIF is a JPEG

JFIF, the JPEG File Interchange Format, is the standard way JPEG images are stored. Most .jpg files are JFIF inside; only the extension differs. Some browsers and Windows save images from the web as .jfif, and many upload forms and apps only look for .jpg or .jpeg.

So the fix is the name, not the picture. This tool copies each file byte for byte under a .jpg name. The quality setting doesn't apply, and the photo's metadata, such as the date and location, stays in the file.

## Renaming by hand

For one file, renaming it does the same. On a Mac, Finder may ask you to confirm the new extension. From Terminal or Command Prompt:

- Mac: mv image.jfif image.jpg
- Windows: ren image.jfif image.jpg

## Questions

### Are my files uploaded?

No. They're read and saved again in your browser.

### Does converting JFIF to JPG lose quality?

No. The file is copied as it is and only renamed to .jpg.

### Why do my images save as .jfif?

Some browsers and Windows settings save JPEG images with the .jfif extension. The data is the same JPEG; only the name differs.

### Is the photo's metadata kept?

Yes. Because the file isn't re-encoded, the date, camera and location stay in it. Convert to PNG if you want them gone.
