About the JFIF format
JFIF is technically a JPEG photo with a different file extension — Windows sometimes saves images from the web this way. Many upload forms and programs reject the unfamiliar .jfif ending.
Why convert to JPG?
JPG (or JPEG) is the most widely used image format on the web. It uses lossy compression that keeps photos small in file size, and it is supported by virtually every device, browser, app and online form ever made. Choose JPG when you need maximum compatibility and small photo files — for uploads, e-mails, online applications and web use.
