# Tools-PDF Compare

The **Tools** module in TestWheel provides document comparison utilities that help users identify differences between document versions and validate content accuracy efficiently. The module includes features such as **PDF Compare** and **DOCX Compare**, allowing users to analyze changes between uploaded documents in a centralized interface.

## PDF Compare&#x20;

Selecting the **PDF Compare** option from the Tools menu opens the PDF Compare page, where users can upload and compare PDF documents, as shown in the screenshot below.

Users can click the **Browse File** option to select the required PDF files for comparison. After uploading the files, clicking the **Compare** button initiates the document comparison process.

Once the comparison is completed, the system automatically generates a comparison report highlighting the **detected changes**, **content differences**, and **modified sections** between the uploaded PDF documents.

## 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.testwheel.com/tools-pdf-compare.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.
