2. What is ODT?

ODT (OpenDocument Text) is an open-source document format used for word processing. It is the default format for open-source office suites such as LibreOffice and Apache OpenOffice.

Key Features of ODT:

ODT is ideal for those who need a flexible and editable format for creating and modifying text documents.

3. What is PDF?

PDF (Portable Document Format) is a widely used file format developed by Adobe. It is designed to present documents consistently across different devices and platforms.

Key Features of PDF:
