Watermarks are essential in defining the ownership of the PDF document. Here are the steps to add and edit watermark in PDF with UPDF on Mac.
You need to move to the “Watermark” tab on the left column. Click on the “Create” button on the bottom-right of the screen.
Set a watermark as a "Text," "Image," or a "PDF." Here you can choose the Ratio and Opacity of the watermark across the document. Make appropriate settings for Tile Watermark and define whether it should be present on the Front or Back of the document. Click "Save" to create a new watermark.
You can also add watermarks on the pages you want. Click the double arrow icon in the upper right corner. Here you can choose Page Range and Odd or Even Pages for the watermark to be added.
To edit a watermark, find the created watermark in the right column. Hover your cursor to the watermark and click on the "Edit Watermark" icon.
With the editing panel opened across the right-handed column, set all parameters to be edited. Click "Save" once done.
If you intend to delete a watermark, find it across the right column. As you reach out the watermark, click on the “Remove Watermark” icon across it. After that, click the "Apply" button. This will successfully delete the watermark on your PDF too.
