For those using WebP on WordPress sites, what are you using to convert your JPEG/PNG images before uploading them to the Media Library? Or are you converting post upload via code or plugin?

On one website there was 1000 jpegs which I used custom code to convert to Webp in batches.

What I want to know, is there an easy way to convert them beforehand?

Any particular desktop apps, websites or batch converters you recommend that keep the quality good while reducing file size?

Just looking for a simple workflow that keeps the site lightweight.

Curious what everyone is using for website images nowadays - JPEG, AVIF or WebP?

When making websites on Wordpress I’ve generally stuck with WebP (converting) because it seems like a good balance between image quality and file size, and I’ve found it helps with PageSpeed compared with standard JPEGs.

Just wondering if AVIF has now become the better option, or whether WebP is still the safer/default choice for WordPress and WooCommerce sites.

Would be good to hear what others are using in practice, especially anyone focused on Core Web Vitals and keeping sites lightweight.
