Frequently Asked Questions
How much can I reduce the file size?
Results depend on the original PDF structure. Some files get smaller; already optimized files may not shrink at all. This tool does not recompress embedded images.
Will compression affect PDF quality?
The tool repacks PDF objects without resizing pages or recompressing embedded images. Check the downloaded copy before sharing it.
Can I compress password-protected PDFs?
No. Unlock the PDF with its owner-approved password first, then select the unlocked copy.
Is compression permanent?
The tool downloads a separate copy only when it is smaller. Your original file stays unchanged.
