What is a hybrid PDF file?
This is a PDF file, which can be read like any other PDF, which it also has the source document in ODF format, allowing you to modify it using LibreOffice. 
To create a hybrid PDF
- create or open your document in LibreOffice. All document types available in LibreOffice are supported;
- go to ▸ ;
- check to insert the ODF editable file into the PDF;
- you can also change the other parameters such as the image resolution. Do not forget that large images make for large documents; and
- click the Export button and complete the save operation (choice of folder and filename).
The PDF that you have just created can be opened in the usual way with any program that can read PDFs but it will also be editable with LibreOffice using drag-and-drop.
All PDFs that you will create from this moment forward by export from LibreOffice will be hybrids until you uncheck this option.
