Email programs usually stop at about 20 to 25 MB, and uploads on many portals stop at just a few MB. A scanned PDF can blow past both, even when it only has six pages.
Find out why it is big
Text-only PDFs are tiny. Big ones are nearly always scans, where each page is a full-size photo. That is also where you can save the most.
Rebuild it smaller
Turn the pages into images with the PDF to JPG tool, shrink them if needed, then put them back together with the JPG to PDF tool at medium quality. The new file is often a fraction of the size.
Or send it another way
If it still will not fit, upload it to a cloud drive and share the link, or split the document into two logical parts and send them separately.
Free, no signup, and your files never leave your device.

Can WhatsApp send bigger PDFs than email?
Usually yes, WhatsApp accepts much larger documents than email does. Big files still send slowly and can fail on a weak connection, so smaller is safer.
Is it okay to lower quality for official documents?
Yes, as long as every line of text stays readable when you zoom in.
