Works Offline — Install as an App
CompressEazy is a Progressive Web App (PWA). That means you can install it on your device and use it exactly like a native app — no internet connection required. Your images are processed 100% on your device, so nothing ever gets uploaded, even when you're offline.
How to Install CompressEazy
Click the install icon ⊕ in the address bar (right side), then click "Install". CompressEazy will open in its own window and appear in your app launcher.
Tap the Share button ⎙, scroll down and tap "Add to Home Screen". The app icon will appear alongside your other apps.
Tap the three-dot menu ⋮ and select "Install app" or "Add to Home screen". It'll install instantly — no app store needed.
What Works Offline?
- All compression, resizing, and format conversion tools
- All 16 specialized tool pages (compress to target size, resize for Instagram, convert HEIC, etc.)
- Bulk compression and ZIP download
- Side-by-side before/after comparison
Once you visit the site, all pages and assets are cached automatically. The next time you open it — even without Wi-Fi or mobile data — everything works instantly. When you reconnect, the app silently updates itself in the background.
