Part 1: Which is the Desired Photo Format, AVIF V.S. WebP

Just as mentioned above, both photo formats are the successor of JPEG and PNG photos. But what are the advantages of these two new image formats? Which image format is more desirable? Here are some important differences between AVIF and WebP.

AVIF V.S. WebP Usage

AVIF is a photo format based on the open-source AV1 video codec, which supports a transparent background and is capable of storing a series of animation frames, just like high-quality GIF animation. Moreover, it is the photo format that supports HDR colors.

WebP is a VP8 video codec-based photo format that supports both lossy and lossless compression. The lossless WebP also supports transparency that is much smaller than the PNG files. Both lossy and lossless and transparency are all supported in animated WebP images.

Part 3: FAQs about the Differences between AVIF and WebP

1Can I convert videos to AVIF or WebP?
Yes. But similar to animated GIFs, when you convert videos to AVIF or WebP, you cannot get the audio files. If you just need some animated files on your website, you can use AVIF or WebP. Of course, you can upload the videos to YouTube and add the links to your website.
2Why is the converted AVIF or WebP larger than JPEG?
When you compare the photos with similar quality, JPEG should be much larger than AVIF and WebP. But the professional photo converters upscale the photo quality for the two file formats. Just tweak the quality and duration to get the desired photos accordingly.
3Can I import both types of files in Photoshop?
In Photoshop 23.2, Photoshop fully supports the WebP file format, so you can now open, create, edit and save WebP files in Photoshop without plug-ins or preferences. AVIF format files, however, it is not included. You must use a file converter or install Photoshop's AVIF plug-in beforehand.
