Compress PDFs to fit a 2MB upload limit. 2MB is generous enough for large documents with high-quality images, many pages, and rich formatting.
2MB is a relaxed cap that accommodates almost any reasonable document. Common for high-resolution scanned reports, detailed technical documentation, presentation handouts as PDF, and academic papers with figures. The usual challenge is just lossless optimisation.

Use it for technical reports, design portfolios, scanned books or thesis documents, high-resolution scanned legal documents, and presentation handouts converted to PDF for email distribution.
For PDFs over 5MB before compression, the most likely cause is high-resolution embedded images. After this lossless pass, if you're still over 2MB, use Acrobat's Save As Optimized with 'Subsample images to 150 ppi' for substantial further reduction.
