Easily correct, update, and enhance PDF files. Resize, move, or replace images— without returning to your original source document.
Place an image or object into a PDF
Move or resize an image or object
- To move the image or object, drag it to the desired location. You cannot drag images or objects to a different page (you can cut and paste them to a new page instead). Shift-drag the object to constrain movement up or down, or right or left.
- To resize the image or object, select it, then drag a handle. Shift-drag the handle to retain the original aspect ratio.
If you select multiple objects, you can move or resize them together.
Rotate, flip, crop (clip), or replace an image
Flip Vertical Flips the image vertically, on the horizontal axis.
Flip Horizontal Flips the image horizontally, on the vertical axis.
Rotate Counterclockwise Rotates the selected image ninety degrees in the counterclockwise direction.
Rotate Clockwise Rotates the selected image ninety degrees in the clockwise direction.
Crop Image Crops or clips the selected image. Drag a selection handle to crop the image.
Replace Image Replaces the selected image with the image you choose. Locate the replacement image in the Open dialog, and click Open.
To rotate the selected image manually, place the pointer just outside a selection handle. When the cursor changes to the rotation pointer , drag in the direction you want it to rotate.
Move an image or object in front or behind other elements
The Arrange options let you move an image or object in front of or behind other elements. You can push an item forward or back just one level, or send it to the front or back of the stacking order of elements on the page.
Under Objects in the right hand panel, click Arrange and choose the appropriate option.
Alternatively, you can right-click the object (or objects), and point to Arrange and then choose the appropriate option.
For complex pages where it is hard to select an object, you may find it easier to change the order using the Content tab. (Choose View > Show/Hide > Navigation Panes > Content.)
Align images or objects
The Align Objects options let you precisely align multiple objects on a side - Left, Vertical Centre, Right, Top, Horizontal Centre, and Bottom.
When you align objects relative to each other by their edges, one of the objects remains stationary. For example, the Left option aligns the left edges of the selected objects with respect to the left edge of the leftmost object. The leftmost object remains stationary, and the other objects are aligned relative to it.
The Horizontal Centre option aligns the selected objects horizontally through the centre of the objects, and the Vertical Centre option aligns the selected objects vertically through the centers of the objects. The objects are aligned along a horizontal or vertical line that represents the average of their original positions. An object can remain stationary, if it is already aligned to the horizontal or vertical line.
Depending on the alignment option you select, objects move straight up, down, left, or right, and might overlap an object already located there. If you see an overlap, you can undo the alignment.
Edit an image outside Acrobat
You can edit an image or graphic using another application, such as Photoshop, Illustrator, or Microsoft Paint. When you save the image or graphic, Acrobat automatically updates the PDF with the changes. The applications that appear in the Edit Using menu depend upon what you have installed and the type of image or graphic you have selected. Optionally, you can specify the application you want to use.
Under Objects in the right hand panel, click Edit Using and then choose an editor.
To choose a different editor than offered on the menu, select Open With, locate the application, and click Open.
If a message asks whether to convert to ICC profiles, choose Don’t Convert. If the image window displays a checkerboard pattern when it opens, the image data could not be read.
- Make the desired changes in the external editing application. Keep in mind the following restrictions:
- If you change the dimensions of the image, the image may not align correctly in the PDF.
- Transparency information is preserved only for masks that are specified as index values in an indexed color space.
- If you are working in Photoshop, flatten the image.
- Image masks are not supported.
- If you change image modes while editing the image, you may lose valuable information that can be applied only in the original mode.
In the editing application, choose File > Save. The object is automatically updated and displayed in the PDF when you bring Acrobat DC to the foreground.
For Photoshop, if the image is in a format supported by Photoshop 6.0 or later, your edited image is saved back into the PDF. However, if the image is in an unsupported format, Photoshop handles the image as a generic PDF image, and the edited image is saved to disk instead of back into the PDF.
