(1) Create a New Transparent File

Select File > New from the menu. A window opens this includes the option to make the file transparent.

Once the new file has been created, add your image content to one or more new layers. This will happen automatically if you copy and paste an image into the file.

(2) Add a Transparent Layer

You can add a transparent layer to an existing file by selecting Layer > New > Layer from the menu.

The new layer will be added above the currently selected layer. Drag the new layer below the image's layer.

Whichever method you use, you should end up with at least two layers. The image content is on one layer, positioned above the transparent background layer.

Notice how the transparent layer is checkered. This pattern is not part of the image - it is just there to help you identify transparent areas.

Make sure the content layer is selected before you continue.

Using the Magic Wand or Lasso tool, select the area of the image you want to be transparent.

You may want to experiment a few times with the tolerance and anti-aliasing settings to get the best selection.

Hit the Delete button. The selected area is removed and the checkered (transparent) background becomes visible.

Now that you have a transparent background you can save the file in a variety of formats, including GIF, TIFF, PNG and of course PSD.

JPG format does not support transparency.

If you find ugly edges around the image when you place it against a different background color,

Sometimes when you make a transparent GIF and place it in an environment with a background color (e.g. on a web page) you find that an ugly border appears around the image. The example on the right shows a transparent image placed on a purple background. As you can see there is a thin but nasty edge to the image.

This happens because the edges of the image need to gently transition into the background color. In this example Photoshop has assumed that the background will be white, so it has faded the edges towards white. To fix the problem you need to tell Photoshop to fade the color towards the actual background that you will be using.

Save as Indexed ColorTo do this you need to use the matte feature. When you select "Save As" you will see a window like the one on the right. Select the Matte drop-menu, then select Custom. A color-picker window will appear — enter the color of your background.

Note: If this is for a web page you should be able to copy the hex color from the web page HTML or stylesheet, and enter it into the color-picker window.

Continue to save the file. If all goes well, it should now blend nicely into the background.

Remember that this file will only blend nicely with the specified color, so if you change the background color you are back to square one. As always, it makes sense to save a copy of the master PSD file so you will always be able to change your mind.

Answer 3

You could copy it into PowerPoint, choose Show Picture Toolbar, then Set Transparent Color, click the bit you want transparent, then copy it back into Photoshop.

Answer 4

Umm... I haven't used Photoshop for a while now. Best thing to do is probably go to Help>Contents and type "transparent". It should help.

Answer 5

I think you have to set it as a background or as a watermark

Answer 6

You can highlight an area and then press the delete key normally.
