Why Are PDF Files Often Huge?
It is common to encounter a 10-page PDF that weighs over 45 MB. The primary culprits behind PDF bloat include:
- High-DPI Embedded Scans: Multifunction office scanners frequently embed images at uncompressed 600 DPI.
- Embedded Font Subsets: Duplicate typography definitions stored inside the document dictionary.
- Redundant Object Streams: Unused revision history and metadata saved by PDF authoring software.
