Most of these programs have a built-in feature to flatten PDF files. This can be particularly useful if you need to manage a large number of PDF documents regularly.

Important Notes:

Flattening a PDF can significantly increase the file size because the merged elements are converted to images, which take up more space. Ensure you have a backup of the original file before flattening, especially if it contains sensitive information. Flattening can make the PDF file non-searchable. Ensure that searchable text remains if you need to maintain this feature.

By choosing the right method, you can effectively flatten your PDF files, making them more secure and easy to share with others.
