Frequently asked questions
How much can this shrink my PDF?+
It depends on the file: image-heavy or metadata-heavy PDFs shrink the most, while already-optimized PDFs may barely change.
Does it reduce image quality inside the PDF?+
No, this tool optimizes file structure and strips unnecessary metadata rather than recompressing embedded images.
Will formatting or content change?+
No, the visible content and layout stay the same. Only the underlying file structure gets optimized.
