A few useful answers

How much smaller will my PDF become?

It depends on the document. Image-heavy PDFs usually have more room for reduction. An already optimised file may not become smaller.

Will compression change image quality?

Lower quality settings may soften images. Choose print quality for documents where fine image detail matters.

When are my files deleted?

Your task shows the exact expiry time. Files are removed automatically after expiry, or you can use “Delete now” to remove them sooner.
