Although a lot of modern applications can render image conversions at build time, a custom conversion is sometimes requested for an image to be set as `webp`. - -You *could* download one of the many native apps from the Mac App Store to do this for you - but why not create your own script and run it with a simple right-click directly inside Finder? **Let's do just that!** - -## Basic requirements - -**Important!**: As of this time of writing, the official `libwebp` package release is *libwebp-1.2.1-mac-10.15*.

When trying to run `cwebp` he received the following error message: - - - cwebp cannot be opened because it's from an unverified developer - - -Doing the next steps seemed to have fixed this issue for him: - -1. Click on the "Open in Finder" in the error message prompt -2. Double-click on the `cwebp` utility to open in Terminal -3.
