WEBP to AVIF

WEBP to AVIF for squeezing out extra savings

WEBP is already an efficient format, so moving to AVIF is about finding the last chunk of savings. If your site uses large images, or your audience is mainly on mobile, this WEBP to AVIF converter can help you trim page weight a bit further without changing your layouts.

AVIF comes from the AV1 video codec and tends to handle smooth areas, like skies and skin, particularly well. It preserves transparency too, so logos and cut-outs can make the switch.

How to convert WEBP to AVIF

All encoding takes place on your device, so speed depends on your computer or phone.

1. 1

   Select WEBP images

   Use WEBP files from your site's media folder, or any you've saved. You can drop up to 20 at once.

2. 2

   Choose an AVIF quality

   Your WEBP has already been compressed, so stay a little higher than usual. A setting of 70 to 85 is a good range.

3. 3

   Encode

   Press Convert to AVIF, then give it a moment. AVIF encoding takes more processing than WEBP.

4. 4

   Decide what to keep

   Compare sizes on the result cards. If an image didn't shrink much, it's fine to stay with the WEBP.

WEBP vs AVIF

Neither format replaces JPG or PNG for sharing files with people. They're both for delivering images on websites.

Start from the best source you have

Converting one lossy format to another stacks compression on compression. If you have the original files, it's better to go straight from them with JPG to AVIF or PNG to AVIF.

This page is most useful when WEBP is all you've got, such as images already published on your website, or stock files you've saved in that format. In that case, keep quality on the higher side and check the output against the source.

Is the switch worth the effort?

• Likely yes: large banner images, photo galleries, image-heavy landing pages.
• Maybe: product photos in a store. Test a sample before converting the whole catalog.
• Probably not: small thumbnails, icons and flat graphics, where WEBP is already tiny.
• No: images that people need to download and open elsewhere. For those, use WEBP to JPG.

Runs locally

The encoder is downloaded to your browser, and your files stay on your device, with no sign-up or watermark. If you ever need to go back, AVIF to WEBP does the reverse.
