Frequently asked questions
How much can I reduce the file size?
It depends on the PDF. Files with lots of metadata or uncompressed streams can shrink significantly. PDFs that are already optimized may see minimal reduction.
Will compression reduce image quality?
No. This tool optimizes PDF structure (metadata and streams) without re-encoding images. Visual quality is preserved.
