Question details
The user needs to apply a standard watermark to every page of numerous PDF files organized across various nested subfolders.
- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Adding a uniform watermark, such as 'Copy', to a large batch of PDF documents distributed across a complex folder structure without opening each file individually.
- Observed behavior
- The goal is to automate the watermarking process to save time and apply consistent formatting to all PDFs within the selected folders.
Ensure you have full read and write permissions for all the subfolders involved, and consider backing up your original PDF files to a separate directory before running any batch editing processes.
Use the Action Wizard in Adobe Acrobat Pro
The Action Wizard is ideal for creating a reusable, automated process to apply watermarks across nested folders.
Acrobat Pro includes an Action Wizard feature that lets you define a set of commands and apply them to multiple files or entire folders, including their subfolders. This saves significant time for repetitive tasks that you might need to perform regularly.
Launch Adobe Acrobat Pro. Go to 'Tools' and select 'Action Wizard'.
Click on 'New Action' in the Action Wizard toolbar to set up a custom batch process.
Under 'Choose tools to add' on the left panel, navigate to 'Pages', select 'Add Watermark', and click the '+' icon in the middle to add it to your action steps on the right.
Uncheck the 'Prompt user' box so the process runs automatically. Click 'Specify Settings' to define your watermark text (e.g., 'Copy'), font, size, and opacity.
Under 'Files to be Processed', click 'Add Folder' and choose the parent folder containing your PDF subfolders. Save the Action, give it a name, and click 'Start' to process the files.
Use the Apply to Multiple Files Option
A quicker method for a one-time batch watermark process without needing to create and save a permanent Action.

Frequently Asked Questions
Can I use an image as a watermark instead of text for my batch process?
Yes, both Adobe Acrobat and WPS Office allow you to upload an image file (such as a company logo in PNG or JPG format) to use as a watermark when configuring your batch process settings.
Will watermarking hundreds of PDFs overwrite my original files?
By default, some batch actions may overwrite the original files if not configured otherwise. It is highly recommended to set the output destination in your Action Wizard or batch tool to save the watermarked PDFs to a new folder.
How do I remove a watermark if I made a mistake during the batch process?
If you need to remove the watermark later, you can use the 'Remove Watermark' tool (Tools > Edit PDF > Watermark > Remove) in Acrobat or the corresponding removal tool in WPS Office, provided the documents have not been flattened.
Can I apply different watermarks to different subfolders at the same time?
No, a single batch process will apply the exact same watermark configuration to all selected files and folders. To apply different watermarks, you must configure and run separate batch processes for each specific folder.
