178
- The big win is the HTML → Markdown step: trafilatura strips all tags, scripts, styles, navigation, and ads, keeping only the main content. This cuts 421.1 GB of uncompressed HTML down to 15.1 GB of markdown — a **98.3% reduction** — before any file-level compression is applied. Parquet with Zstd level 19 then compresses the markdown a further 68.1%.

- End to end: ~141.0 GB of raw gzipped WARCs becomes **4.8 GB of Parquet** — a **96.6% total reduction** — containing 3,400,017 clean markdown documents.
