Comes out as WebP. You can change this once your images are in.
Output
Everything re-converts as you change it
Around 80 to 90 is where most pictures stop looking different but keep getting smaller.
JPEG cannot be transparent, so whatever was see-through gets this colour.
Aspect ratio is kept, and a picture already smaller than this is left alone.
More than one image comes back as a single .zip.

Metadata is dropped
Redrawing the picture leaves the EXIF block behind, so camera model and GPS coordinates do not come along. The rotation a phone records is applied first, so the result is the right way up.
Your browser sets the limits
Only formats this browser can write are listed, which is why AVIF appears on some machines and not others. Animation is not carried over: a GIF or an animated WebP comes back as its first frame.
Why convert PNG to WebP
WebP keeps transparency like PNG while being a fraction of the size, which is why it is the usual choice for images on a website. Every current browser displays it.
Worth knowing
This WebP is lossy with a quality you set. For logos and pixel art check the preview, since hard edges show compression first.
Questions people ask
Is transparency kept in WebP?
Yes. Unlike JPG, WebP has an alpha channel.
Do all browsers show WebP?
All current ones do: Chrome, Edge, Firefox and Safari since version 14.
Are my images uploaded to convert them?
No. The browser decodes the file, redraws it and encodes it again on your own machine. Nothing is sent unless you sign in and choose to save the result to your account.
Can I convert several images at once?
Yes. Drop as many as you like, and more than one result downloads as a single .zip.
Is the metadata kept?
No. Redrawing the picture leaves the EXIF block behind, so camera model and GPS position do not come along. The rotation a phone records is applied first, so the result is the right way up.
