How to convert images to WebP
WebP delivers smaller files than JPEG or PNG at the same quality and is now supported by every modern browser. OctoSqueeze converts your images to WebP in one step, so you can serve lighter pages without sacrificing how they look.
Why WebP matters
Lighter images load faster, improve your Core Web Vitals, and save bandwidth for you and your visitors. On mobile especially, a 2 MB hero image can be the difference between a bounce and a conversion.
WebP vs. AVIF
WebP has the widest support today; AVIF goes even smaller where it's supported. Export both and serve AVIF first with a WebP fallback for the best of both.
Do it at scale
Converting one image is easy. Converting thousands is what our REST API is for — one call returns an optimized file (or a CDN URL) in any format you need.
