Why is my PDF so large?
If a portal rejects your upload, the cause is usually images—not a mysterious “PDF tax”. Diagnose the source, then compress toward a real limit.

High-resolution images
Photos and screenshots embedded at print resolution dominate file size. Colour pages cost more than grayscale scans.
Scanned pages
Each scanned page is effectively a picture. Multipage identity or invoice packs multiply quickly.
Design and office exports
Exports from design tools or print drivers can embed unused assets. Flattened exports may still keep large bitmaps.
Fonts, duplicates, page count
Embedded fonts and repeated resources add overhead. Long page counts amplify whatever is on each page.
FAQ
- Does deleting metadata fix a 50 MB scan?
- Rarely. Metadata is small compared with page images. Focus on image compression and a clear target.
