Hi!
I’m a researcher and data scientist from Spain and the maker behind Chapa Lab.
I built Estruja because compressing a file or creating a ZIP shouldn’t require uploading private documents to an unknown server, creating an account, or dealing with complicated software.
Estruja brings the everyday file tools I frequently need into one simple browser app:
📦 Create and open ZIP files
🖼️ Compress images
📄 Compress PDF files
📝 Compress Word and other Office documents
🔒 Process everything locally in your browser
🚫 No uploads, accounts, subscriptions, or installations
💚 Completely free to use
Your files never leave your device. That combination of simplicity and privacy is what makes Estruja different from most online file tools.
Estruja is part of Chapa Lab, my growing collection of small, useful, privacy-friendly web tools.
I’d love to hear your honest feedback. Which Estruja tool would you use most, and what should I add next?
Thank you for checking it out!
