AVIF vs WebP: what changes
AVIF and WebP are both modern web formats with transparency and animation, but WebP has been around since 2010 and is accepted by more content systems, email services and image tools. Converting is a practical choice when a platform takes WebP but rejects AVIF.
Expect the WebP to be somewhat larger than the AVIF, since AVIF usually compresses better. The converter writes lossy WebP at 92% quality and keeps transparent areas, while an animated AVIF is reduced to its first frame.
How to convert AVIF to WebP on any device
Content management systems
Some site builders and plugins accept WebP uploads but not AVIF. Convert here, then upload the WebP files to your media library as usual.
Keeping transparency for the web
Logos and product cut-outs stay transparent in WebP, so you can replace an AVIF asset without adding a background behind it.
Many files at once
Choose images accepts a whole selection on desktop and mobile. Several AVIF files come back as one ZIP with the original names and a .webp extension.
Troubleshooting AVIF to WebP
The converter reports that my browser does not support AVIF
This message means the browser itself cannot decode AVIF, which is common on systems that have not been updated in years. Any current Chrome, Edge or Firefox works, as does Safari on macOS Ventura, iOS 16 or later.
The WebP is larger than the AVIF
That is normal: AVIF generally needs fewer bytes for the same look. Use WebP where compatibility matters, and keep the AVIF wherever it is accepted.
Fine detail looks slightly softer
Both formats are lossy here, so the picture is compressed a second time. The difference is rarely visible at 92% quality, but keep the AVIF as your master copy.
Color profile and metadata
The WebP is built from the decoded image, so metadata such as EXIF and XMP is dropped, which also strips location details before you publish. HDR and wide-gamut colors are converted to standard sRGB, so very bright or saturated areas can look more muted.
