Why We Built This Tool

Image optimization is a core part of our SEO services work. We convert hundreds of images to WebP every month for our clients because page speed directly impacts rankings.

All our SEO consultants are trained to optimize images as part of technical SEO. We built this extension so you can do the same—quickly and privately.

During our SEO audit process, we often find massive unoptimized images—sometimes 5MB photos that should be 200KB. These slow down pages dramatically and hurt Core Web Vitals scores.

Frequently Asked Questions

Does this work offline?

Yes! Once installed, the extension works completely offline. No internet connection needed for conversions.

Is there a file size limit?

No artificial limits. You're only limited by your device's available memory. Most users can convert files of any reasonable size without issues.

Is there a limit on number of files?

No! Convert as many images as you need. The batch processing feature handles large numbers of files with a progress indicator.

What about transparent images?

WebP fully supports transparency. Your PNGs with transparent backgrounds will convert perfectly with transparency preserved.

Will I lose image quality?

You control the quality setting with a slider. At 80-90%, most images are visually indistinguishable from the original while being significantly smaller.
