Is my file secure on AdvancePDF?
Yes. Files are processed only to complete the requested task and are deleted afterward. For hardening before sharing, use Protect PDF. You can also review our Privacy Policy and About page.
Why didn’t my file size shrink much?
Some PDFs are already optimized or contain pre-compressed images. In those cases, size reduction can stay limited even with Compress PDF.
What file size limit do you support?
AdvancePDF supports large uploads up to 200 MB for most tools. If a file fails, try Compress PDF first.
