PDF Optimizer
PDF File Optimizer
A tool that reduces PDF file size by compressing images, removing unused objects, and optimizing the document structure.
Teknik Detay
PDF Optimizer uses a logical structure tree embedded in the PDF to define headings, paragraphs, lists, tables, and figure captions. Screen readers traverse this tree rather than the visual layout, enabling correct reading order even in complex multi-column designs. The tag structure follows the PDF/UA (ISO 14289) standard and maps closely to HTML semantics, making well-tagged PDFs navigable with keyboard-only and assistive technology.
