# Enumeration: UseObjectStreams

Defines how to use object streams when saving a PDF document.

## Enumeration Members

### Multiple

> **Multiple**: `2`

Uses multiple object streams. This may slightly increase the file size compared to "Single", but the PDF will open without delay in a viewer.

***

### None

> **None**: `0`

Do not use object streams.

***

### Single

> **Single**: `1`

Use a single object stream for the entire document. Enabling this option can significantly reduce the PDF file size, though it may introduce a delay when opening the PDF in a viewer.
