Should you convert APNG to AVIF?

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

APNG is a PNG that animates, with full color and soft transparency; AVIF is a modern image format that squeezes photos smaller than WebP. Use AVIF for photos on a website when you want the smallest files and can serve a fallback to older browsers.

How to convert APNG to AVIF

  1. 01

    Add your APNG

    Drop your APNG 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 AVIF. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the AVIF

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

What changes when APNG becomes AVIF

Transparency is kept

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

Animated files keep their first frame

AVIF can animate, but this converter writes animated AVIF only for GIF and APNG targets. An animated APNG is saved as a still of its first frame.

Expect a much smaller file

APNG: Larger than a GIF of the same animation, but in full color. AVIF: Often around half the size of the equivalent JPG. Shrinking the file is often the main reason to make this conversion.

This page is put together from our notes on each format, choosing only what is true of APNG and AVIF, 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 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.
  • 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.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting APNG to AVIF lose quality?

AVIF is lossy, so some detail is discarded. The quality slider decides how much; the default of 90 is chosen so the difference is invisible in almost every photo.

Will the AVIF be smaller than the APNG?

Expect a much smaller file. APNG: Larger than a GIF of the same animation, but in full color. AVIF: Often around half the size of the equivalent JPG. Shrinking the file is often the main reason to make this conversion.
