What the Book Metadata Extractor does

Good metadata is what makes a book findable and sellable — and it is tedious to assemble by hand. Upload a PDF or EPUB and this free metadata extractor reads the file, samples the pages where bibliographic data lives (title page, copyright page, colophon), and returns clean metadata normalized to the ONIX for Books 3 standard: title and subtitle, contributors with role codes, publisher, dates, identifiers, language, BISAC and Thema subjects, and retail keywords.

Where the file already carries embedded metadata, that always wins; the AI fills the gaps and suggests classification and keywords in the language of the book. You get a structured record you can drop straight into a catalog, plus a copy sent to your inbox.

It is free and private, one book at a time. Only sampled excerpts are analyzed, and your file is deleted immediately after.

When to use it

  • Building a catalog record from a manuscript or finished file.
  • Filling in missing BISAC / Thema subjects and retail keywords.
  • Standardizing contributor roles to ONIX List 17 codes.
  • Spot-checking the metadata embedded in a file you received.
