What would a presentation be like without any pictures? Undoubtedly, pictures add more value and aesthetics to your slides. However, some users skip the idea of adding images as their images are not suitable for slides. Some of the problems are that pictures are clipped or lack perfect brightness. Fortunately, you can perform various image editing tasks directly in Google Slides. In this post, we bring you 15 tips for editing images like a pro in Google Slides.
This post lists the steps for Google Slides on the web. However, the tips will also work in mobile apps. Also, many of the tips are also available for other Google Drive services such as Google Docs and Google Drawings.

When you add an image to Google Slides, it will be used in its original size. Therefore, you may need to resize or rotate it.
Click on an image to resize it. When the blue border appears around the picture, resize the picture by dragging it with the help of the corner boxes. You can use the small boxes in the middle of the frame, but that will not preserve the aspect ratio.

Pro Tip: Learn how to batch resize images.
Similarly, to rotate an image, select it by clicking on it. Then rotate the image using the small circular icon at the top of the image. Alternatively, if you want to rotate an image 90 degrees or flip it horizontally/vertical, right-click the image and select Rotate. Choose the appropriate option.

You can also manually adjust the dimensions of the image, the rotation angle, and even lock the aspect ratio. For this, right-click on your image and select Format options. The right sidebar will open. Click Size and rotation to expand. Then set the parameters according to your need.

Pro Tip: To change the position of an image, simply drag it. Or right click the image and go to Format options. Then manually enter the location of the image under the Location section.

When aligning images, it is not possible to ensure that they are properly placed for other elements. You can enable alignment lines to make things easier. These will guide you as you move your images.
To enable them, go to View > Snap To. Click on Guides.
