How to Use the Add Page Number to PDF Tool

Last Updated: October 11, 2025

Navigate to the Nova Tools homepage and locate the "Add Page Number" tool card in the Tools section. Click the card, which displays a numbered list icon and the description "Add customizable page numbers to your PDF documents," to open the page number modal.

After clicking the tool card, a modal titled "Add Page Numbers to PDF" will appear. This modal contains an upload area for selecting a PDF file. You can close the modal by clicking the "×" button in the top-right corner or clicking outside the modal.

Click the "Choose PDF File" button in the upload area or drag and drop a PDF file (`.pdf`) into it. The selected file’s name (e.g., "Selected: document.pdf") and details (name, size) will appear in the file list below. Only one PDF file can be selected; choosing a new file replaces the previous one.

Click the "Add Page Numbers" button to open the options modal. Configure the following:

• Page Number Position: Choose from Bottom Right, Bottom Left, Top Right, or Top Left.
• Font Size: Set the size (8–24 pt, default 12 pt).
• Font Color: Select a color using the color picker (default black).
• Start Page Number: Specify the starting number (minimum 1, default 1).

Click the "Process" button to add page numbers. A progress bar will show the processing status for each page. The button will be disabled during processing. If no PDF is selected, an alert will prompt you to upload a file.

After processing, the "Process" button is replaced by a "Download Result" button with a download icon. Click it to download the numbered PDF, named `numbered_pdf.pdf`. The modal remains open for further actions.
