About WebP and AVIF
WebP supports transparency and is widely supported by modern browsers.
AVIF gives the smallest files but encoding is slower than WebP or JPEG.
WebP files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.
Limitations
- AVIF encoding is noticeably slower than JPEG or WebP.
Frequently asked questions
How do I convert a WebP file to AVIF?
Add your WebP file to the box above. convertexa detects the format from the file content, applies the WebP to AVIF conversion and gives you the result to download. The whole operation runs inside your browser.
Are my WebP files uploaded anywhere?
No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.
Is the WebP to AVIF conversion lossless?
No. AVIF is a re-encoded format, so some data is discarded to reach the target format. WebP supports transparency and is widely supported by modern browsers.
Is there a size limit?
For reliable results keep the input under 40 MB. Very large files run out of memory in the browser rather than failing quietly.
Which browsers are supported?
Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
