Should you convert JFIF to PNG?

A .jfif image needs to be edited or placed in a design tool that expects PNG.

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

PNG is also the more widely supported of the two: it opens everywhere, while JFIF is has patchy support.

JFIF is an ordinary JPEG photo that carries the .jfif extension; PNG is a lossless image format with full transparency. Use PNG for screenshots, interface graphics, logos and anything with transparency or lettering, and as the working copy of an image you are still editing.

How to convert JFIF to PNG

  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 PNG. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the PNG

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

What changes when JFIF becomes PNG

PNG can’t add back what JFIF removed

The JFIF was compressed when it was saved, and that detail is gone. PNG 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

PNG is far bigger for the same content. Choose it because something needs PNG, not to send or store the file. JFIF: The same size as the equivalent JPG. PNG: A 12-megapixel photo is often 12–20 MB; a screenshot is usually 100 KB–1 MB.

This page is put together from our notes on each format, choosing only what is true of JFIF and PNG, 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 PNG. Photographs saved as PNG balloon in size. A holiday photo that is 3 MB as JPG can be 15 MB as PNG, because lossless compression can do very little with the fine grain of a real photograph.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting JFIF to PNG lose quality?

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

Will the PNG be smaller than the JFIF?

Expect a much larger file. PNG is far bigger for the same content. Choose it because something needs PNG, not to send or store the file. JFIF: The same size as the equivalent JPG. PNG: A 12-megapixel photo is often 12–20 MB; a screenshot is usually 100 KB–1 MB.
