Squoosh wins on 100% privacy (local processing), completely free, more codec options

Squoosh processes images entirely in your browser using WebAssembly. This is great for privacy but means large files can be slow or even crash the browser tab. SharpWebP processes on cloud servers, delivering fast results regardless of your device. If you're on a phone or low-powered laptop, SharpWebP is noticeably faster.
This is where SharpWebP and Squoosh fundamentally differ. Squoosh is strictly a one-image-at-a-time tool — no batch processing, no API, no WordPress plugin. SharpWebP supports batch uploads, a REST API for automation, and a WordPress plugin for automatic optimization. For production use, SharpWebP is the clear choice.
Squoosh's biggest advantage is privacy: your images never leave your device. Everything happens in-browser. SharpWebP processes images on cloud servers, which means your files are uploaded temporarily. If you work with sensitive images (medical, legal, confidential), Squoosh's local processing is a significant advantage.
Squoosh supports a wider range of codecs including OxiPNG, MozJPEG, WebP 2, and more experimental formats. SharpWebP focuses on the three most important next-gen formats: WebP, AVIF, and JXL. For most users, SharpWebP's format selection covers all practical needs.
