How client-side PDF optimization works
Navureno uses WebAssembly/JavaScript bytecode to parse PDF structural dictionaries directly inside your browser. It removes duplicate fonts, strips redundant metadata tags, and applies binary object-stream deflation. Because no server upload occurs, your confidential contracts, tax documents, and legal filings remain 100% private on your machine.
How it works
- 1.Parses the binary PDF dictionary structures using WebAssembly/JavaScript bytecode.
- 2.Strips unneeded metadata tags, cleans object references, and applies binary stream compression.
- 3.Generates an optimized PDF file locally for immediate download.
