如何刪除 PPT 背景圖片：桌面版和線上版

製作PPT時，我們經常需要設定多個不同風格的模板，並插入預先準備好的圖示或圖片。但很多素材圖片都有背景色。如果頁面上的顏色過多，會顯得雜亂，所有元素隨意堆疊，無法構成一個完整的設計。

So we must deal with it seriously and perform PPT removing the background image . PowerPoint itself has two ways to realize this operation. But if you want to experience a more brilliant background removal service, you can try the best online tools recommended in the article. We will not continue to nag; we will immediately start to see how to do it.

一、如何刪除PPT中的背景

製作 PPT 時，你可以手動處理 PowerPoint 中的圖片。它的介面上有兩個工具可以幫助你去除圖片背景。接下來，我們分別從這兩種情況來看如何操作。

使用“設定透明顏色”功能刪除背景

第一種是為圖片加上透明色效果。這種方法非常適合單色的圖片，而且效果立竿見影。

以下是如何使用透明色彩功能去除 PPT 中影像的白色背景。

Step 1. Open your PPT. Navigate to the image you want to edit. Please select it and choose Format in the toolbar.

Step 2. Find Color in the top left corner. Expand the menu and choose Set Transparent Color.

Step 3. Your cursor will become a pencil. Hover it on your image and click. The background color of your image will be transparent.

請注意，此方法不適用於背景有陰影的影像。此外，如果圖片中的物體顏色與背景過於接近，透明度功能可能會同時擦除背景和物體。

使用刪除背景功能刪除背景

您會在 PowerPoint 頁面的左上角看到一個「刪除背景」按鈕。點擊它，PPT 刪除背景程式會自動識別背景並高亮顯示要刪除的部分。

以下是如何使用「刪除背景」功能從 PPT 幻燈片中刪除背景圖像。

Step 1. After inserting your image into your slide, select it.

Step 2. Click Picture Format > Remove Background.

Step 3. The platform will run and detect the background automatically. The background will be highlighted in purple. You can also choose Mark Areas to Keep or Mark Areas to Remove to adjust the frame manually.

Unfortunately, there is a common problem with this feature and the Transparency Effects feature. They are both very bad at detecting the background and are likely to erase the core objects in the image. And even if you try to adjust it manually, PowerPoint will still follow its idea when executing it. If your picture background is dark or not a single color, try to find another more innovative tool to remove or add background to your image.
