When PNG to AVIF pays off

PNG keeps every pixel exactly, which makes photos, product cut-outs and detailed screenshots heavy. AVIF stores the same picture with lossy compression and still keeps the alpha channel, so a product photo on a transparent background can stay transparent on your website at a fraction of the size. The list shows the size before and after for each file, so you see the gain right away.

  • Big gains: photos saved as PNG, cut-outs from the background remover, screenshots of photos and video.
  • Smaller gains: flat logos, icons and charts, which PNG already stores compactly. Use a high quality for those.

Quality for graphics and text

Lossy compression is kind to photos and harder on sharp edges. For screenshots with text or for logos, start at 85 or more and zoom in on the result. If edges look fuzzy, raise the quality or stay with PNG. For photos, the default of 80 is a good start, and lower values save more.

Starting from photos instead? Use JPG to AVIF. Need a format that every app opens? PNG to WebP keeps transparency too, and AVIF to JPG converts back.

How it works

  1. 1Drop your PNG files on the box. Transparent ones are welcome.
  2. 2Set the quality. Every file converts again when you let go of the slider. The first AVIF may download the encoder, about 1.1 MB.
  3. 3Save the AVIF files one by one or all at once as a ZIP.

Frequently asked questions

Is the transparent background kept?

Yes. AVIF has an alpha channel, so see-through areas, soft edges and shadows in your PNG stay transparent. There is no background color to pick.

Is AVIF lossless like PNG?

The AVIF format can be lossy or lossless, according to MDN. This converter saves AVIF at the quality you set, and lower quality means a smaller file. For logos and text, use a high quality so edges stay crisp, and keep the PNG as your master copy.

Why does the first AVIF take longer?

If your browser can write AVIF itself, the page uses that. If not, it downloads an AVIF encoder the first time you convert: a file of about 3.5 MB, sent compressed as about 1.1 MB. Your browser keeps it in its cache, so the next images start right away. You can also switch to WebP, which keeps transparency too.

Where can I use AVIF files?

On websites: MDN lists AVIF support in Chrome 85, Edge 121, Firefox 93 and Safari 16.1 or newer. Some apps, office programs and upload forms still do not accept AVIF, so keep the PNG for those.

Are my images uploaded?

No. Your browser opens each PNG and writes the AVIF on your own device. Nothing is sent to a server.
