Compress a PDF before upload: realistic size targets and when not to expect miracles
Published
Reduce PDF file size for email, portals, and mobile data. What compression can and cannot fix on scan-heavy documents.
Compression helps when a PDF must fit an upload limit, email cap, or slow mobile connection. It works best on office PDFs with vector text and embedded fonts. Full-page photo scans may barely shrink because the image data is already dense.
Set a target size before you start
Know the portal limit (5 MB, 10 MB, 25 MB) and compress once, then check visually. Running multiple passes rarely helps scanned stacks.
Keep an uncompressed archive copy
Store the original for records; share the compressed export for delivery.
