Should you convert JFIF to APNG?

Worth it when an app or an editor needs APNG, or before you edit the picture several times. APNG won’t restore the detail JFIF already threw away, and the file will be larger, but nothing more is lost from here on.

APNG 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; APNG is a PNG that animates, with full color and soft transparency. Use APNG for small animated graphics on the web where GIF’s color banding or jagged edges would show.

How to convert JFIF to APNG

  1. 01

    Add your JFIF

    Drop your JFIF image onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to APNG. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the APNG

    Press convert and save the APNG. Several files come back together as a ZIP.

What changes when JFIF becomes APNG

APNG can’t add back what JFIF removed

The JFIF was compressed when it was saved, and that detail is gone. APNG records exactly what the JFIF contains now, compression marks included, and keeps it that way however often you edit and re-save.

Expect a much larger file

APNG is far bigger for the same content. Choose it because something needs APNG, not to send or store the file. JFIF: The same size as the equivalent JPG. APNG: Larger than a GIF of the same animation, but in full color.

This page is put together from our notes on each format, choosing only what is true of JFIF and APNG, so every pairing states the same facts the same way. How these pages are made.

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 APNG. An APNG usually still ends in .png, so an upload form or editor treats it as a still picture and the animation silently disappears.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting JFIF to APNG lose quality?

No further quality is lost: APNG keeps exactly what is in the JFIF. It can’t undo compression the JFIF already has.

Will the APNG be smaller than the JFIF?

Expect a much larger file. APNG is far bigger for the same content. Choose it because something needs APNG, not to send or store the file. JFIF: The same size as the equivalent JPG. APNG: Larger than a GIF of the same animation, but in full color.
