In this article, you can learn how to store and view entire photo libraries in your Documents app as well as how to highlight important details and draw on your images with the handy “Mark up” mode.

You can access your entire photo library through our integration with the Photos app. To do so, simply open Documents > Photo Albums folder.

There are also other ways to add images to Documents:

• Add or take images using the plus button at the bottom right
• Share images from other apps to Documents
• Download them from our built-in browser 
• View and mark up images from any cloud storage connected to Documents without downloading them

Mark up photos and images

The markup tools can be used in many different ways, like pointing out something attention-worthy, highlighting the details, showing design changes, using it as an educational tool, or just making your images more colorful and catchy.

Create a drawing

1. In Documents, open the needed image and tap.
2. In the Markup toolbar, tap the pen , marker , or pencil  tool, then write or draw with your finger.
3. To hide the Markup toolbar and save changes, tap Done.

While drawing, do any of the following:

• To change the thickness, tap the drawing tool in the toolbar, then choose an option.
• To change the opacity, tap the drawing tool in the toolbar, then drag the slider.
• To change the color, tap the Color Picker button  in the toolbar, then choose a color.
• To draw a straight line, tap the ruler tool in the toolbar, then draw a line along the edge of the ruler.

Move your drawing

After you draw something, you can move it around. To do so, tap the Lasso  tool, trace a circle around the drawing that you want to move, then drag it where you want it to be.

Erase or undo a drawing

To undo a drawing, tap the eraser button and rub your finger across the area you want to erase. You can also undo any markup action by using the undo button. If you accidentally undo a markup, you can tapto redo.
