Questions

Are my PDF files uploaded?

No. These PDF tools run in your browser. Files are not uploaded to ToolDesk.

Will every PDF work?

Most standard PDFs work. Encrypted, restricted, scanned, or unusually large PDFs may have limited support in browser-based tools.

Can browser compression match desktop PDF software?

Lossless mode only optimizes PDF structure. Balanced and Smallest modes re-render pages as images, which shrinks scanned and image-heavy PDFs much more but makes text non-selectable.
