Should you convert JFIF to WEBP?

A safe conversion when WEBP is what you need: both JFIF and WEBP keep every pixel, so the picture itself doesn’t change.

WEBP is also the more widely supported of the two: it opens in current browsers and apps, while JFIF is has patchy support.

JFIF is an ordinary JPEG photo that carries the .jfif extension; WEBP is a web image format that can be lossy or lossless, with transparency and animation. Use WEBP for pictures on your own website or app, where every kilobyte affects load time.

Why it doesn’t upload

Changing a picture’s format is work your browser already knows how to do. Sending your photos to a server first only adds waiting and risk, so nothing is sent.

How to check for yourself

Worth knowing

  • About the JFIF. People assume a .jfif file is a special format. It is a normal JPEG; the only real problem is forms that look at the extension and say no.
  • About the WEBP. Images saved from websites arrive as WEBP even when the page looked like it showed a JPG, and then a document editor or upload form refuses them.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.
