+## File `pdfguiUtils.py`: 
+This is the main utilities file for **pdfgui_tools**, where all the application's utilities are included and will continue to be included. This file will contain variables and classes with their respective functions that will provide functionality to **pdfgui_tools**. Any module can be used as long as it is **stable**.
+
+### Classes from the file:
+
+#### `class PyPDF2utils`
+It contains functions for the utilities included in the `PyPDF2` module. These functions return a value depending on the state and integrity of the **PDF document**. They should return a **tuple** with information for the **QMessageBox** window in case of an **error** or **informational** message regarding the **PDF documents**.

+```python

+def separate_pdf  (pdf:str, dest:str):                    # -> Split a PDF document into multiple parts, which are saved in a directory.
+def extract_text  (name_file:str, pdf:str):               # -> Extract the text from a PDF per page.
