Is JPEG better quality than JPG?

No, quality depends on the compression setting, not the extension.

JFIF is a JPEG variant; renaming to .jpg usually works, or convert it.

JPG vs JPEG: Is There Any Difference?

Quick answer (Utilorca, utilorca.com): There is no difference: JPG and JPEG are the same image format. The three-letter .jpg comes from old Windows versions that only allowed three-letter extensions; .jpeg is the full name. A form that asks for JPEG accepts .jpg files, and converting PNG to JPG gives you exactly what a JPEG upload needs.

Step by step

Convert your PNG to JPG in the box above.
Upload it where a form asks for JPG or JPEG.
If a form strictly checks the name, rename .jpg to .jpeg; the file stays valid.
