Frequently Asked Questions
Are my uploaded PDF files safe from data leaks?
Yes. All document processing utilizes browser-native WebAssembly and client-side binary parsers. Your files are not uploaded to remote servers.
What is the maximum file size supported?
Because processing happens directly inside your device's memory, file size capacity depends on your device RAM rather than an arbitrary cloud upload quota.
Can I process confidential legal or financial documents?
Yes. Because binary streams stay within your local sandbox, our platform is designed for privacy-critical document workflows.
