Private, High-Speed & 100% In-Browser PDF Suite
Zero server uploads. No queues. Total confidentiality for every document.
Most people don't realize that when they merge, compress, or convert documents on typical online converters, their private files travel over the internet to remote cloud storage. Invoices, tax statements, medical records, and enterprise blueprints end up cached on third-party servers.
KraftDoc was built to fix this fundamental privacy flaw. By leveraging modern WebAssembly (WASM) and browser-native memory virtualization, KraftDoc executes 100% of PDF parsing, rendering, page splitting, and compression directly inside your device's web browser.
Absolute Privacy Sandbox
Your files never leave your computer or phone. They reside in temporary RAM and are cleared automatically when you finish.
Hardware-Accelerated Speed
Zero waiting for file uploads or cloud processing queues. Merging and splitting happen at native device speeds.
