Will WebP be bigger than the AVIF?

Typically yes, by roughly a quarter or more at equal visual quality. AVIF's codec is stronger, so a WebP that looks the same usually costs more bytes.

Is a second lossy pass a problem?

Some detail is lost each time you re-encode. Around quality 85 to 95 the added artifacts are hard to see, but keep the AVIF or original as your master.

Does transparency carry over?

Yes. The image is drawn on a transparent canvas, and no white fill is used for a WebP target, so alpha stays intact.

Which browsers can encode WebP for this tool?

Chrome, Edge and Firefox can write WebP from a canvas. If yours cannot, the browser may hand back a PNG instead, so check the saved file if the size looks off.

About AVIF to WEBP

Converts an AVIF to WebP, a widely supported lossy format with an adjustable quality slider. Both formats support transparency, so cutout graphics survive. It is useful when a platform, CMS or design tool accepts WebP but not yet AVIF.

How to use it

Drop an AVIF file onto the drop zone, or click to browse for a .avif file.
Check that the Source preview appears, which shows your browser can decode AVIF.
Set the Quality slider (10 to 100, default 85) using the Smaller file and Better quality labels.
Press Convert to WebP and look over the Output panel.
Press Download WebP, or Reset to start over.

When to use it

Uploading an AVIF picture to a content platform that whitelists WebP, JPEG and PNG.
Supporting browsers older than Safari 16.4, which cannot show AVIF but display WebP.
Comparing the sizes of two modern formats for the same source image.

Good to know. An animated AVIF turns into one still frame. Color depth is reduced to 8 bits per channel by the canvas, and metadata is not kept.
