Fórmula y Método de Cálculo
Optimized PDF = Downsampled Images (72 DPI) + Flatted Layers + Subset Fonts
The primary bulk of a PDF is usually high resolution print images. Downsampling 300 DPI print graphics to 72 DPI screen resolution instantly sheds megabytes of unnecessary data.
Mejores Prácticas y Consejos
- Know Your Target Medium: If a PDF is destined for professional offset printing, never compress it. If it is destined to be read on a smartphone or emailed, aggressively compress it to screen resolution (72 to 144 DPI).
- Flatten Interactive Elements: Forms, annotations, and multi layered vector graphics add significant hidden bloat. Flattening the PDF bakes these elements into the page, saving space and preventing accidental edits.
- Use Vector Text When Possible: A scanned PDF (where the text is just a giant image) will always be massive. A native PDF (where text is rendered via fonts) is infinitely smaller and fully searchable.
