AI-Generate Backgrounds for PDF

Adding backgrounds to PDFs is a great way to enhance the aesthetics of your documents. But finding the exact background design you need can be tricky. You'll have to spend hours searching online. Even then, most background images come with fees and copyright.

The AI-Generate Background feature makes things easier by helping you generate your own background designs directly in UPDF. You can create any type of background without worrying about fees or copyright issues.

Follow the step-by-step guide below to learn how to use this feature.

Part 1. How to AI-Generate Background for PDF

UPDF allows you to generate three high-resolution background images from one text prompt. You can either type the background description manually or use preset prompt options.

Here are the steps.

Step 1. Open the PDF in UPDF and click “Tools” from the top. Then, select “Background” under the Edit PDF section.

Step 2. A toolbar for backgrounds will appear at the top. From here, click the “AI Background” option

The window for the AI Generate Background tool will open. From here, you can generate backgrounds in two ways using AI.

Method 1. Generate Background with a Personalized Prompt

To generate a background image, you can type in a detailed description of the design. You can personalize it with descriptions of your desired background style, color, and aesthetic.

Here’s how it works.

Step 1. In the text box, under Describe the Background, type in the background details you want to generate. You can add as many details as you want.

• For example, you can write a prompt to “Generate a light green checkered notebook paper background.” Once you’re done customizing your prompt, click the “Send” button.

Step 2. UPDF AI will produce three high-resolution PNG background images based on your description. You can view these under the “Generated Background” section.

Please note that one complete AI generation will produce 3 backgrounds and uses up to 3 credits. If an unexpected issue occurs and the AI produces fewer than 3 backgrounds, the credits will be deducted only for the backgrounds successfully generated.

Method 2. Generate Backgrounds with Smart Presets

The smart presets allow you to automatically generate a background description instead of manually writing it. You can still customize the description to add more details if needed.

Here’s how it works.

Step 1. Under the prompt box, you’ll see several preset options. Click the one you want to use, and the relevant background description will appear in the prompt box.

• For example, if you click the “Plants” preset, it will insert the prompt to generate the linear blades and floral outlines in a specific layout.

Step 2. Edit and modify the preset prompt if needed. Then, click the “Send” button. This will create three AI backgrounds and show them under the “Generated Background” section.

Step 3. If you cannot find a preset you want to use, click the “Refresh” button on the right. This will replace the available presets with new options.

Part 2. Managing AI-Generated Backgrounds

UPDF allows you to easily manage and reuse your AI-generated backgrounds. You have the options to save the backgrounds in UPDF or download them to your device. You can also add them directly to your document and customize their appearance.

To do this, follow these steps.

Step 1. After generating backgrounds with AI, hover your cursor over the image you want to use. This will show three options to manage the background.

• Star: Click the “Star” icon to save the background for future use in UPDF.
• Download: Click the “Download” icon to store the background as a PNG file on your device.
• Add: Click the “+” button to place the background directly on your PDF.

Step 2. After adding the AI background to your PDF, an Edit Background panel will appear on the right. From here, you can customize your background’s Size and Opacity. You can also define the Page Range to apply the background.

Step 3. You can also check the “Automatically add to starred” option. Then, click “Done” to add the background to the “Starred” section in UPDF.

To find the saved background, click the “Add Background” option from the top and go to the “Starred” tab.
