The tool reduces file size by removing unnecessary data: metadata (author, dates, keywords), form fields (by flattening them into static content), and annotations (comments, highlights, sticky notes). It also uses object streams for more efficient internal structure.
Three levels: Light strips only metadata (author, title, dates). Medium adds form flattening. Aggressive also removes all page annotations. Each level preserves the visual appearance of your PDF.
No. This tool does not re-compress images or change the visual content. It only removes metadata and structural elements that are not needed for viewing. The pages look identical before and after compression.
Savings vary widely depending on the PDF. Files with extensive metadata, forms, or annotations can see 5-30% reduction. Simple PDFs with minimal metadata may see little to no change. The tool shows exact before/after sizes.
Yes. All compression happens in your browser. No data is uploaded to any server. The tool uses pdf-lib for client-side processing and works offline once loaded.
