Why PDFs become huge
Scans and embedded images usually dominate PDF size. A short document can still be very large if its pages are stored as high-resolution images.
One page containing a full-resolution photo can outweigh many pages of text.
Complex exports can carry extra resources.
Some PDFs contain duplicated objects that add weight without visible benefit.

Why is my PDF too large?
High-resolution scans, photos, embedded fonts, and duplicated document data are common causes.
Can a PDF be under the size limit and still fail?
Yes. Portals may also enforce page count, format, encryption, dimensions, orientation, filename, or other rules.
Can Ninjitzu compress a PDF locally?
Supported compression workflows are designed to run in the browser.
