Trafilatura is a Python package and command-line tool which seamlessly downloads, parses, and scrapes web page data: it can extract metadata, main body text and comments while preserving parts of the text formatting and page structure. The output can be converted to different formats.


  • Seamless and parallel online/offline processing:
    • Download and conversion utilities included
    • URLs, HTML files or parsed HTML trees as input
  • Robust and efficient extraction:
    • Main text and/or comments
    • Structural elements preserved: paragraphs, titles, lists, quotes, code, line breaks, in-line text formatting
    • Extraction of metadata (title, author, date, site name, categories and tags)
  • Several output formats supported:
    • Text (minimal formatting or Markdown)
    • CSV (with metadata, tab-separated values)
    • JSON (with metadata)
    • XML (for metadata and structure) and TEI-XML
  • Link discovery and URL lists:
    • Focused crawling and politeness rules
    • Support for sitemaps and ATOM/RSS feeds
    • Efficient and polite processing of URL queues
    • Blacklisting
  • Optional language detection on extracted content

This effort is part of methods to derive information from web documents in order to build text databases for research (chiefly linguistic analysis and natural language processing). Extracting and pre-processing web texts to the exacting standards of scientific research presents a substantial challenge for those who conduct such research. Web corpus construction involves numerous design decisions, and this software package can help facilitate text data collection and enhance corpus quality.
