JFIF to JPG questions, answered
What is a JFIF file?
JFIF is the JPEG File Interchange Format, the standard container that ordinary JPEG images have used for decades. A .jfif file is a real JPEG; the only unusual thing about it is the file extension.
Why did Windows save my picture as .jfif?
When an image arrives with the generic MIME type image/jpeg, some Windows and browser combinations pick the registered .jfif extension instead of .jpg, most often for pictures saved from WhatsApp Web, Facebook or email attachments.
Can I just rename .jfif to .jpg?
Usually yes, because the data inside is JPEG either way, and renaming works for most uses. Converting here goes a step further: it re-saves the file as a clean, standards-conforming JPG, which also fixes the strict upload forms that inspect more than the file name.
Why do upload forms reject .jfif files?
Many sites whitelist file extensions rather than inspecting the actual content, and .jfif rarely makes their list. A converted .jpg passes every such filter.
Does converting lose quality?
The image is re-encoded once at your chosen quality; at the default of 85 the change is invisible. If you prefer zero re-encoding, renaming the extension yourself keeps the original bytes untouched.
Are my files uploaded to a server?
No. The conversion runs inside your browser, so nothing is transmitted or stored anywhere.
