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 473.6 GB of uncompressed HTML down to 17.1 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: ~158.9 GB of raw gzipped WARCs becomes **5.5 GB of Parquet** — a **96.6% total reduction** — containing 3,826,504 clean markdown documents.
