Linearized & Web-Optimized PDF Files
Standard PDFs place their Cross-Reference (xref) table at the absolute end of the file. To view page 1, a browser must download the entire 100MB file to read the trailer. Linearization (Web Optimization) solves this by placing a secondary, minimal xref table at the very beginning of the file stream.
These files allow you to test streaming HTTP Range Requests and lazy-loading UI implementations. A properly built web viewer will fetch the first 4KB of a linearized file and instantly render Page 1 without waiting for the rest of the payload.
