The Honest Take
Squoosh is genuinely great. Google's Chrome team built it to showcase what browsers can do, and they nailed it. The side-by-side comparison view is still the best we've seen anywhere—you can literally drag a slider between your original and compressed image while tweaking encoder settings.
What Squoosh nails: That comparison UI is *chef's kiss*. Plus it runs entirely in your browser (maximum privacy), works offline as a PWA, and gives you granular control over encoder settings.
Where we come in: Browser-based processing hits real limits. Large files crash tabs, you can only do one image at a time, and browsers can't decode formats like PDF or RAW camera files. We process on servers—which means handling massive infographics (up to 50,000×50,000 pixels on Pro), batch uploads, PDFs, RAW files for photographers, and a full image editor with crop, color adjustments, watermarks, and more.
Mobile workflow: Our interface is optimized for phones. Bloggers take a photo, edit, optimize, and upload—all from their pocket. Squoosh works on mobile but wasn't designed for that workflow.
The honest take: For carefully optimizing a single image with live comparison? Squoosh is excellent. For batch processing, huge images, PDF/RAW conversion, editing, or mobile workflows? That's where we help.
