In simple terms, rotating PDF pages is like flipping a page to either the right or left to ensure that the text and images are correctly oriented. This rotation is determined by specific angles and degrees that determine how much the document is turned. In PDF editing software, when you rotate pages, each turn involves moving the page by 90 degrees.
In this article, we will discuss 3 methods: a software solution, an online tool, and a command-line utility, all of which can be used to accurately rotate a PDF document by a specified number of degrees.
How to Rotate PDF by Few Degrees using a Free Software
Rotating a PDF file is possible with the widely used desktop application known as IrfanView, which is designed for Windows users. IrfanView is a versatile software package that serves as an image viewer, editor, organizer, and converter. It also supports the playback of video and audio files and offers some image creation and painting functionalities. It’s important to note that IrfanView is freely available for non-commercial purposes, but for commercial use, a paid registration is required.
Working:
1. Click on this link to download IrfanView (32 / 64 bit) for Windows as well as the associated plugins. You must remember to install the plugins too without which you will not be able to rotate the PDF by degrees.
2. Launch IrfanView and press ‘B’ on your keyboard to enter the Batch mode.
3. Load the PDF document from your local system by navigating to the corresponding folder and double clicking the name of the file. You can also add multiple PDF documents if you wish to rotate all of them by the same degree.
4. Next, under ‘Batch Conversion settings’ set the Output format to PDF using the associated drop-down menu.
5. Click on the ‘Options’ button and ensure that the checkbox ‘Save all pages from original image’ is enabled.
6. Now, enable the checkbox ‘Use advanced options’ below the ‘Output format’ drop-down list and click the ‘Advanced’ button.
7. This opens the ‘Set for all images’ dialog box. In the third column, Enable the checkboxes ‘Fine rotation’ and ‘Apply changes to all pages (TIF/PDF saving)’. In the textbox ahead of ‘Fine rotation’ specify the degrees by which you wish to rotate the PDF. For anti-clockwise rotation, the degrees value should be prefixed with a ‘-‘ (minus) sign. For example 4.00 for clockwise, -4.00 for counter-clockwise.
8. Click on ‘Ok’ to save the settings and close the dialog box. Finally, specify the path of the output folder in the ‘Output folder for result files’ text box and then click on ‘Start Batch’.
9. All the PDF files that you have added will now be rotated by the specified degrees and saved in the output folder.
