Vibe coded a nifty little WordPress plugin that turns JPGs, PNGs, & GIFs into WebP.

Used Claude for it. At first used Sonnet and well hours later it was still buggy. Then I used Opus and within 5 minutes it was done. Had to do one revision, because I forgot a feature I wanted. But it works! It actually works!

I know using AI is problematic. But not knowing what these tools can do isn’t good either.

You can check it out here: [sethgoldstein.me/webp-imag…](https://sethgoldstein.me/webp-image-converter/)

I don’t promise it won’t blow up your WordPress site… so no warranties. HAHA But it’s working for me! If you have suggestions on how I can make it better put a comment below and I’ll make those changes in 1.0.2.

Cheers!
