About this tool

PDFs accumulate cruft. Editors leave behind stale metadata, duplicated objects and inefficient cross-reference tables, especially after several rounds of editing or exporting. Optimizing rewrites the file with compact object streams and strips document metadata, without re-encoding a single page.

The savings are usually a few percent, occasionally much more for documents that have been round-tripped through several tools. What you gain besides size is cleanliness: authorship, title and producer fields are cleared, and the file opens as a tidy, modern PDF.

Choose this over Compress PDF whenever the text layer matters — searchable contracts, documents heading for OCR-free archiving, or anything a colleague will copy text from.

What it's good for

  • Cleaning a document before publishing it publicly.
  • Removing author and title metadata from an exported file.
  • Tidying a PDF that has been through several editors.
  • Shaving size off a text document without losing selectable text.
