# shared/overview/optimization

PDF Optimizer optimizes PDF documents by reducing the file size, removing redundant information, and compressing data streams using the latest in image compression technology.

It can compress and shrink PDF file size with the following operations:

* Remove duplicated fonts, images, ICC profiles, and any other data stream.
* Optionally convert high-quality or print-ready PDF files to small, efficient and web-ready PDF.
* Optionally down-sample large images to a given resolution.
* Optionally compress or recompress PDF images using JBIG2 and JPEG2000 compression formats.
* Compress uncompressed streams and remove unused PDF objects.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/reusable-content/shared/shared-overview-optimization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
