What people use it for

Bulk-optimizing images before a site launch.
Getting one ZIP of WebP files instead of converting one by one.

Very large batches use more memory since everything is processed and zipped locally.

Frequently asked questions

Why WebP?

WebP typically produces much smaller files than JPG or PNG at the same visual quality, which speeds up page loads. The main reason to batch-convert a site's images.

Do I get one file or many?

All converted images are bundled into a single ZIP for one download, which is faster than saving each file separately.

Are my images uploaded?

No. Conversion and zipping both run in your browser; nothing is sent to a server.
