Question 2

Which formats can I convert to?

Accepted Answer

JPG, PNG, WebP and AVIF.

Question 3

Are my images uploaded to a server?

Accepted Answer

No. The whole tool runs inside your browser, so your images never leave your device. The site's security policy also blocks the page from sending files anywhere.

Question 4

Which format should I use for the web?

Accepted Answer

WebP is supported everywhere and is much smaller than JPG or PNG. AVIF is even smaller but slower to encode.

Question 5

Why does AVIF take longer?

Accepted Answer

AVIF uses a very efficient but compute-heavy encoder. It runs in the background so the page stays responsive.
