The text and images of PDF files sometimes cannot maintain their original layout during the creation or conversion process. Therefore, using a good PDF editor can help you easily move and align various elements in the document. TechEDMentor may be the tool you need.
1. Open a PDF with TechEDMentor, and then click Edit on the toolbar;
2. Select multiple elements;
- Mac User: Hold down Command to select multiple text boxes or images or box an area to select multiple elements;
- Windows User: Hold down Ctrl to select multiple text boxes or images or box an area to select multiple elements;
3. Choose the alignment in the right-side properties panel or the floating bar according to your needs.
Note: If the properties panel does not appear, click Properties in the upper right corner to show it.
