- The big win is the HTML → Markdown step: trafilatura strips all tags, scripts, styles, navigation, and ads, keeping only the main content. This cuts 3.1 TB of uncompressed HTML down to 117.1 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 68.3%.

- End to end: ~1.1 TB of raw gzipped WARCs becomes **37.2 GB of Parquet** — a **96.6% total reduction** — containing 25,971,452 clean markdown documents.
