FAQ
Optimize PDF for email FAQ
Email attachment tips.
Why not zip instead?
Zipping helps little on already compressed PDFs; recompressing images inside the PDF works better.
Grayscale savings?
Converting color scans to grayscale often cuts size dramatically.
Still too large?
Split the document into multiple emails or use a secure file link.
Quality check?
Open the optimized PDF and zoom to ensure text remains readable.
