1. Local-First Processing
MicroPng is designed with a "local-first" philosophy. Most image processing (compression, resizing, filtering) happens directly in your browser using WebAssembly. Your original images never leave your device for these operations.
2. Server-Side Compression
If you choose "Server Mode" for better compression ratios, your images are temporarily sent to our secure, ephemeral worker. These images are processed in-memory and the result is streamed back to you immediately. **We do not store your images or any metadata associated with them.** Once the request is completed, the data is completely wiped from the server's memory.
3. Analytics
We use PostHog for anonymous usage analytics to help us improve the tool. We track events like "image compressed" or "format changed," but we do not collect personal data, IP addresses in a way that identifies you, or any content of the images you process.
4. Cookies
We use minimal cookies for essential site functionality and for the anonymous analytics mentioned above. You can disable these in your browser settings, though it might affect some features.
5. Changes to This Policy
We may update this policy from time to time. Any changes will be posted on this page with an updated revision date.
