About This Tool
Clean up PDF files by removing unused objects with our free online PDF optimizer. Eliminate orphaned resources and unreferenced data that accumulate through editing, reducing file size without affecting visible content.
PDFs edited multiple times in Adobe Acrobat or other editors often contain obsolete objects, deleted pages, and unreferenced resources that bloat file size. Our cleaner identifies and removes this hidden data while preserving all visible document content and functionality.
All PDF cleaning happens locally in your web browser. Your documents never upload to external servers, ensuring privacy for frequently-edited business documents, revised contracts, and iteratively updated reports.
Perfect for cleaning up documents after multiple revisions, reducing bloat from PDF editing workflows, optimizing files for distribution after updates, or preparing final versions for archival. Safe operation that only removes non-visible, unreferenced content. Works with all PDF files from Adobe Acrobat Pro, Foxit, and other PDF editors.
