How to Perform Batch PDF Watermark on Windows or Mac

Adding a digital stamp to PDFs is essential for professionals looking to brand their documents or secure their content from unauthorized use. In such scenarios, the ability to apply a batch PDF watermark proves to be a game-changer for those who frequently handle multiple files. Whether adding your company's logos, a confidentiality notice, or a custom text, having an efficient tool to process numerous documents simultaneously saves time and effort.

If you are tired of manually editing watermarks for each file, this article is for you. We will explore how you can streamline the watermarking procedure with tools that offer flexibility in placement, opacity, and bulk file processing.

Part 1. Can I Watermark Multiple PDFs at Once?

You might be wondering if there's advanced software capable of watermarking multiple PDF files at once. The answer is yes! With powerful PDF editing solutions, you can efficiently batch watermark PDF files in a single operation. One such solution is UPDF, a comprehensive PDF editor with various editing features, including merging multiple files into one before applying a watermark.

With the help of this tool, you can apply a watermark in different forms, such as images, text, or PDF. Users get to adjust the opacity level of the added watermark so that it smoothly blends into the PDF. After the batch PDF watermark, you can later use the split feature to separate the merged files and use them individually as per your requirements.

Part 2. How to Add Watermarks to Multiple PDFs in Batch on Windows 10/11 & macOS

Moving on from UPDF's features allowing users to add batch watermarks, let's dive into how you can achieve this using UPDF on any of your Windows or macOS devices. Before getting started, make sure to download and install UPDF to access its powerful features.

Consequently, follow the steps below to understand the best way to batch PDF watermark Win 11 or Mac with UPDF:

Step 1. Install UPDF and Open the PDFs

Start the procedure by installing and launching the UPDF watermark-adding tool on your desktop. Then, click on the "Open File" button at the main interface to add a PDF from your system.  

Step 2. Choose Batch Combine to Merge Documents

Within the UPDF main interface, access the "Batch PDFs" tab and choose the "Combine" option. This will allow you to add multiple PDFs into one for adding watermarks simultaneously.

On the next screen, add the PDFs that you want to add watermarks to. If you added a wrong PDF, you can simply remove it from the list by clicking the three-dot icon behind it and choose "Remove File". After successfully adding the PDFs you want, click "Apply". UPDF will merge them into a single PDF.

Step 3. Shift to Page Tools and Add a Watermark

Upon adding all your PDFs into one file, navigate to the "Page Tools" section and pick the "Watermark" option. When you choose "Watermark," an extended sidebar appears on the right side where you need to click the "Add" button to batch watermark PDF files.

Step 4. Add a Watermark and Save to Apply the Changes

Next, choose one of the three options—"Text," "Image," or "PDF"—to add a watermark and adjust the properties according to your needs. You can customize the watermark's tiling type, adjust its ratio and opacity, and set it either in front of or behind the content. If you're adding a text watermark, you can also customize the font and font color.

Once you are satisfied with how the document looks, hit the "Save" button to apply the changes made to all the pages of the document.

Step 5. Split the Pages and Export PDFs Separately

Finally, you can split the pages of the merged documents so that you can use them individually. To do this, move back to the "Organize Pages" interface and access the "Split" drop-down menu. From here, choose to split the document based on the page number or custom split range.

Part 3. Bonus Tip: How to Prevent Your PDF Watermarks from Being Removed

Managing thousands of PDF files, such as those for a sheet music publisher, often requires creating preview versions with watermarks. However, standard watermarks can be easily removed using editing tools that leave your files unauthorized. To ensure your batch PDF watermark remains intact, a more secure approach is essential.

With UPDF's PDF flatten feature, you can make your watermarks permanent by embedding them directly into the PDF content. Follow these simple steps to secure your watermarked PDFs and get complete control over your documents:

Step 1. Navigate to the Save as Flatten Feature of UPDF

After you are done batch watermarking PDF files, click on the "File" tab in the top right corner of the screen. From the drop-down menu, select the "Save as Other" option and choose the "Save as Flatten" feature from the extended menu.

Step 2. Tick the Flatten Watermarks Option and Hit Save As

To conclude this process, tick the checkbox of the "Flatten Watermarks" option in the "Save As Flatten" pop-up dialog box. Then, hit the "Save As" button to save the flattened PDF to your desktop.

UPDF is not just a watermarking tool but an all-in-one PDF solution designed to streamline your workflow. The batch processing feature lets you handle multiple files, saving time on repetitive tasks.
