Why there's no upload step
JFIF is technically the same image codec as JPEG — Windows just sometimes saves downloaded pictures with the unusual .jfif extension, and then upload forms, CMSs, and older apps refuse the file purely because of its name. This tool re-saves the image as a clean standard .jpg, so the 'file type not supported' errors go away. Nothing is uploaded anywhere.
Is my image uploaded anywhere?+
No. The file is re-encoded entirely in your browser.
Is JFIF the same thing as JPG?+
Essentially yes — JFIF is the standard container that JPEG images have used for decades. The problem is only the unfamiliar .jfif extension, which many sites reject without looking at the contents.
Will quality change?+
The image is re-encoded at high quality (92%), which is visually indistinguishable for photos.
How do I stop Windows saving .jfif files?+
It's a registry quirk in Windows' MIME mapping. Easiest workaround: convert the files you need — or save images as .jpg explicitly from the browser's Save As dialog.
