- The big win is the HTML → Markdown step: trafilatura strips all tags, scripts, styles, navigation, and ads, keeping only the main content. This cuts 2.7 TB of uncompressed HTML down to 102.0 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 68.2%.

178
- End to end: ~948.3 GB of raw gzipped WARCs becomes **32.4 GB of Parquet** — a **96.6% total reduction** — containing 22,625,862 clean markdown documents.
