Why Wurstli

The best case scenario
for your images

Stop wasting time on image optimization. Wurstli does in seconds what used to take a workflow.

🗜
Squeeze without thinking

No quality sliders. No settings. No manual. Wurstli automatically picks the best compression — like TinyPNG, but on your Mac, offline, forever free. Drop it like it's hot.

🏷
Names a senior SEO would write

Local AI analyzes your image and generates descriptive, keyword-rich filenames. IMG_4829.jpg becomes modern-home-office-desk.jpg

📐

Every image shows its pixel dimensions at a glance. Always know exactly what you're working with — no Finder inspector needed. Even Wurstli has standards.

🔒
100% local. Always.

No uploads. No cloud. No account. Everything stays on your Mac. That's not a sausage, that's a privacy policy. Your client photos never leave the building.

🤖
AI that runs on your Mac — not someone's server

Wurstli uses Apple's Foundation Models and Vision Framework built into macOS 15. No API keys, no monthly fees, no internet required. The AI is already on your machine.
