Processing on your device…
The file is rewritten with optimized internal structure and object streams. Text and images are not degraded — this is lossless optimization, not destructive compression.
Frequently asked questions
How much smaller will my file get?
It depends on how the PDF was created. Poorly generated files can shrink a lot; already-optimized files less. The exact saving is shown before you download.
Will quality be reduced?
No. This optimization is fully lossless — every page looks exactly the same.
