❓ Frequently Asked Questions
Q: Why do I need to convert CRX to ZIP?
Modern Chromium browsers block direct CRX installation from third-party sites. Converting to an unpacked ZIP lets you audit the source code and install it via "Load unpacked" in Developer mode.
Q: Is it safe to drag and drop my CRX files here?
Yes! The local file converter runs 100% in your browser using Web APIs. Your files are never uploaded to any remote server.
Q: How does the store URL extractor work?
Our edge engine extracts the 32-character extension ID and streams the official binary directly from Google servers, stripping the Cr24 signature header in real-time.
