Add, Edit, and Remove Watermark in PDF on iOS

Watermarks are now considered an essential PDF component for deterring copying. With it, you can protect your PDFs, clearly identifying the source of it and preventing any misuse. That said, if you are into adding, editing, or removing watermarks on iOS, UPDF has covered you! Dive in to learn how!

1. Create and Add a Watermark

Launch UPDF for iOS and open a file. In the bottom toolbar, select the Watermark icon—the first from the right side.

You can add a new watermark or edit a previously added one here.

To add new, simply hit the Add Watermark button, UPDF will provide three options for adding a watermark:

• You can add a text watermark: Enter the desired text to set as a watermark in the Content field. UPDF for iOS gives you a lot of customization options:

1. Color-picker circle (rainbow gradient): Tap to choose the watermark text color.
2. "Aa" icon: Tap to open font style options.
3. "≡" icon: Tap to change the text alignment.
4. "U" with underline icon: Tap to toggle text underlining.
5. "Layout" tabs (“Size”, “Opacity”, “Rotation”, “Ratio”, “Location”): You can adjust the watermark size from 1 to 500. Change the watermark opacity from 0% to 100%. Choose the watermark orientation you like, four options are available. Select the ratio from 0 to 250. Set the location where you want to place the watermark on top of the page or behind the page.
6. "Page Range" tabs: Apply the watermark to every page, current page or select a custom page range for the watermark.

• Or set a local file as the watermark: If you select this option, you can choose any photo from your gallery or file from your iCloud Drive to set as a watermark in the Content field.

• In addition, you can add your favorite watermark template from the "Starred" section. If you haven’t saved any watermarks as favorites yet, you can manually add one from another file that contains a watermark. Then, go to the "Watermark" section and click "Edit". In the pop-up window, click the three-dot icon to access the "Add to Favorites" button.

• Now you can open the document where you want to add this starred watermark template. Go to the "Watermark" section, click "Starred", select the watermark you previously starred, and add it to the document.

Choose any of the above options, then customize the Layout options. Once you have everything set, tap on "Done" at the top right corner of the screen to apply your created watermark. Don't forget to save the file afterward.

2. Edit, Delete, and Add to Favorite

After successfully creating a watermark, if you want to continue editing, deleting, or adding it to favorites, you can select the "Edit" option and tap on the three-dot icon. These three options will appear there:

• Edit
• Delete
• Add to Favourites

If you have added a watermark to your PDF with UPDF and no longer need it, you can remove it by choosing "Delete".
