Should you convert AVIF to APNG?

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

AVIF is a modern image format that squeezes photos smaller than WebP; 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 AVIF to APNG

  1. 01

    Add your AVIF

    Drop your AVIF 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 AVIF becomes APNG

Transparency is kept

AVIF and APNG both support transparency, so transparent backgrounds and soft edges come through unchanged.

Animation comes through

If the AVIF is animated, every frame and its timing is copied into the APNG. APNG keeps full color, so it is usually larger than the same animation as GIF.

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. AVIF: Often around half the size of the equivalent JPG. APNG: Larger than a GIF of the same animation, but in full color.

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 AVIF. AVIF’s savings are real, but encoding is slow, so a batch that takes seconds as JPG can take minutes as AVIF.
  • 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.
