Photoshop allows you to create transparent images (backgrounds, layers or parts that are transparent) using various transparency options via the opacity control or the background contents options that appear when you create a new file. In addition, you can also use the Selection Tool or the Eraser Tool to make only some areas of the image transparent. Many people often add transparency in Photoshop when they want to print on paper with a textured design or want to add an image on a textured background on a website because the texture is visible through the transparent plane. With a little practice, you'll be able to add transparency in Photoshop in no time.
Step
Method 1 of 4: Making the Background Transparent

Step 1. Click " File " → " New"
Navigate to the File option at the very top of the menu and select " New." A new window will appear where you can add settings to your new file in Photoshop.

Step 2. Choose "Transparent"
A menu will appear and in the section that says " Background Contents ", select " Transparent ". It's at the very bottom of the drop-down menu.

Step 3. Click OK
Press the OK option.

Step 4. Look at the layers
Look at the Layers window or the Layers tab in the file settings bar (which will usually open by itself). The background layer will look like a gray and white checkerboard (indicating that the image is transparent).
Method 2 of 4: Making the Layer Transparent

Step 1. Select the layer
Select the layer you want to make transparent by clicking on it from the layer list on the Layers tab.

Step 2. Choose Opacity
Click the numbered box that appears next to Opacity at the top of the Layers tab. The opacity value by default is 100 percent.

Step 3. Lower the opacity
Drag the arrow on the opacity value that appears to change the opacity of the layer. If you want to make the layer completely transparent, you have to change the opacity value to 0 percent.
Method 3 of 4: Making the Selection Transparent

Step 1. Select your layer
Choose a non-transparent layer, but make sure the layer below it covers the transparent background layer.

Step 2. Select the field to change
Make a selection using one of the selection tools.

Step 3. Copy the selection
Click Layer Via Copy.

Step 4. Delete the selection
Hit delete. You will see now your image is hollow.

Step 5. Create a new layer
Place the selection you copied on a new layer.

Step 6. Lower the opacity value
The field in the selection you have selected will become transparent.
Method 4 of 4: Creating a Transparent Image

Step 1. Create or select a layer
Select the layer (should have opacity more than 0 percent, preferably 100 percent). All layers below it must be transparent.

Step 2. Click the Eraser Tool
Select the Eraser Tool in the tool selection bar.

Step 3. Change the settings
Choose the size and shape of the eraser in the drop-down menu that appears after you select the Eraser Tool.

Step 4. Draw an image using the Eraser Tool
Basically, you have to delete the area you "drawn", by opening the transparent layer below it.
