Supports PDF files
Our Compress PDF tool optimizes your PDF's internal structure using object stream compression. This reduces file size by reorganizing the PDF's data more efficiently.
Note: Client-side compression works best on PDFs with uncompressed internal structures. PDFs with embedded images may see modest reductions.
