PDF Resizer doesnt work

[Huismeester]

Ive tried to resize a PDF file, but adobe didn' t succeed.

How can I fix this?

[Test Screen Name]

What sort of resize? Inches/mm or megabytes?

What is "Adobe"? What version?

What do you mean "didn't suceed"? What messages or error do you get?

[Huismeester]

The size is in megabytes, it is Adobe Acrobat.

I didn' t receive an error, but the file didnt got any smaller.

[Test Screen Name]

You use PDF optimiser? Some files get smaller, some do not. There is no magic that will make every file smaller. Usually it can manage to reduce image quality once.
