Before you begin

We're rolling out a new, more intuitive product experience. If the screen shown here doesn’t match your product interface, select help for your current experience.

In the new experience, the tools appear on the left side of the screen.

A background appears behind text or images on the page. The background can be as simple as a solid color, or you can use an image. You can selectively apply a background to only specific pages or page ranges in one or more PDFs. A PDF supports only one background per page, but the backgrounds can vary from page to page.

Add, replace, or edit a background

Open the PDF file to which you want to add the background.
Choose the Edit tool from the global bar. The Edit PDF toolset is displayed in the left pane.
In the Edit panel on the left, select Background > Add.
(Optional) To apply the background selectively to individual pages, select Page Range Options in the top right corner of the dialog box. Then, specify a page range and choose a Subset option, as needed.
Specify the background:
- To reuse a background and background options that you saved in an earlier session, select it from the Saved Settings menu.
- To apply a solid color background, select From Color. Then select a color swatch or custom color from the color picker .
- To use an image, select File, then select the image file. To select a specific image in a multipage file, enter it in Page Number.
Lưu ý:

Only PDF, JPEG, and BMP files can be used as background images.
Adjust the appearance and position of the background, as needed.
(Optional) To apply the same background to additional PDFs:
1. Select Apply To Multiple Files.
2. Select Add Files, choose Add Files or Add Open Files, and then select the files.
3. Select OK.
4. In the Output Options dialog box, specify your folder and filename preferences and select OK.

Update a recently edited background image

If the original image file that you are using as a background change, you can update the PDF to show the new version of the image rather than removing the old version and readding the new one.

Open the PDF file to that contains the background you want to update.
Choose the Edit tool from the global bar. The Edit PDF toolset is displayed in the left pane.
Select Background > Update.
Select OK, or make other changes to the background options and then select OK.

Lưu ý:

This process applies only to backgrounds added in Acrobat 7.0 or later.

Remove a background from selected pages

Open the PDF containing the background.
Choose the Edit tool from the global bar. The Edit PDF toolset is displayed in the left pane.
Select Background > Remove.
Select Yes to confirm the background removal.
