Should you convert PNG to APNG?

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

Bear in mind APNG is opens in current browsers and apps: it works in every current browser and Telegram stickers; most image editors show only the first frame.

PNG is a lossless image format with full transparency; 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 PNG to APNG

  1. 01

    Add your PNG

    Drop your PNG 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 PNG becomes APNG

Nothing is discarded

PNG and APNG both keep every pixel, so the picture survives the move intact. You can convert back and forth as often as you like without it degrading.

Transparency is kept

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

The size stays about the same

PNG and APNG are close in size for the same content, so do this for compatibility rather than to save space. PNG: A 12-megapixel photo is often 12–20 MB; a screenshot is usually 100 KB–1 MB. 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 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.
  • 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.
