Compression level
Frequently Asked Questions
How do I reduce a PDF size?
Upload your PDF, select a compression level (Low, Medium, or High), click Reduce, and download your smaller file. The whole process happens in your browser.
Will reducing PDF size affect quality?
At Low and Medium compression, quality loss is barely noticeable. High compression produces the smallest file but may visibly reduce image sharpness.
Is there a limit to how much I can reduce?
Results depend on your PDF content. Image-heavy PDFs typically shrink 40–80%. Text-only PDFs have less room for reduction.
