Understanding PDF vs Compressed PDF
About PDF
PDF files often become bloated due to high-resolution embedded images, duplicated font subsets, uncompressed metadata, and redundant object revisions.
About Compressed PDF
An optimized PDF cleans unneeded metadata and compacts stream dictionaries, yielding a compact file that loads quickly on mobile devices and fits inside email attachment limits.
When to Use PDF vs Compressed PDF
Compress PDFs whenever an online form rejects your document for exceeding size caps (e.g. 5 MB or 10 MB limits), or when sending multi-page reports to clients.
