Should you convert APNG to WEBP?

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

APNG is a PNG that animates, with full color and soft transparency; WEBP is a web image format that can be lossy or lossless, with transparency and animation. Use WEBP for pictures on your own website or app, where every kilobyte affects load time.

How to convert APNG to WEBP

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

  3. 03

    Save the WEBP

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

What changes when APNG becomes WEBP

Transparency is kept

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

Animated files keep their first frame

WEBP can animate, but this converter writes animated WEBP 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. WEBP: Typically 25–35% smaller than the same 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 WEBP, 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 WEBP. Images saved from websites arrive as WEBP even when the page looked like it showed a JPG, and then a document editor or upload form refuses them.
  • DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.

Questions

Will converting APNG to WEBP lose quality?

WEBP 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 WEBP be smaller than the APNG?

Expect a much smaller file. APNG: Larger than a GIF of the same animation, but in full color. WEBP: Typically 25–35% smaller than the same JPG. Shrinking the file is often the main reason to make this conversion.
