AVIF to WebP Converter
AVIF to WebP: a widely supported format with a similarly small size. Quality or lossless mode, a size limit in KB. Files are not uploaded to a server.
WebP is lighter than JPG and PNG at the same quality and supports transparency. Lossless mode keeps every pixel.
AVIF becomes WebP, a format that opens in almost all browsers and many programs. Transparency is kept, and quality and maximum size are adjustable. The size stays small, though usually slightly larger than AVIF.
AVIF is a modern format based on the AV1 video codec. It gives a very small file at good quality and supports transparency. It opens in recent versions of Chrome, Edge, Firefox and Safari 16.4 and newer, but many programs and phones do not know it yet.
WebP is a format for websites: at the same quality the file is usually 25 to 35% lighter than JPG and PNG. It supports transparency and animation, and lossless mode keeps every pixel. Modern browsers open WebP without trouble.
For WebP you set the quality from 1 to 100 or lossless mode, plus a maximum size in kilobytes: the quality is picked automatically. Transparency is kept by default, but you can fill it with a color. The size in pixels can stay as it is or be changed by width, by height or in percent. Results download one by one or all at once as a ZIP, with random or original names.
Converting AVIF to WebP happens in your browser: files are not uploaded to a server, so it is fast and safe. You can drag several files in, pick them in a file window or paste from the clipboard with Ctrl+V. To open AVIF you need a modern browser: Chrome, Edge, Firefox or Safari 16.4 and newer. Some browsers, Safari in particular, cannot save WebP: in that case use Chrome, Edge or Firefox.
