WebP Resizer

WebP reaches a photograph's quality at a lower file weight than JPEG, which is why it has become the default served format on many sites. This page resamples WebP files and writes them back as WebP, so the resized image does not come out heavier than the one you added.

Frequently Asked Questions About WebP Resizer

Does WebP lose quality when resized?

Any loss comes from the encoder, not the resize, and at matching visual quality a WebP still ends up smaller than the JPEG equivalent.

Can WebP keep transparency?

Yes, it carries an alpha channel, so it can replace a PNG where file weight matters.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the Resized WebP.

What should I check before using the result?

Open the Resized WebP in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

About this workflow

Serving WebP where the browser wants it

A resized WebP is the right file for a modern page, while an older destination may still need JPEG or PNG. Keep the original and export the format each use asks for.

Before downloading the result

Open the Resized WebP next to the original at full size and check text edges, faces, and flat backgrounds; re-encoding softens detail long before it looks wrong in a thumbnail.
