- The big win is the HTML → Markdown step: trafilatura strips all tags, scripts, styles, navigation, and ads, keeping only the main content. This cuts 2.8 TB of uncompressed HTML down to 106.7 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%.
177
 
178
- End to end: ~992.1 GB of raw gzipped WARCs becomes **33.9 GB of Parquet** — a **96.6% total reduction** — containing 23,654,237 clean markdown documents.
