Question 1

How much is the size reduced?

Accepted Answer

It depends on the PDF. Those with photos or scanned pages usually shrink a lot; text-only ones are already small and barely change.

Question 2

Is quality lost?

Accepted Answer

Only in images, which are saved at a lower resolution. Text stays just as sharp. If you need to print detailed photos, use "Light compression".

Question 3

Is it free?

Accepted Answer

Yes. All LeuPaPDF tools are free and you do not need to sign up.

Question 4

Are my files uploaded to a server?

Accepted Answer

No. The file is processed inside your browser, on your device. Nobody else can see it and it is gone when you close the tab.
