Edit Images in WordPress

Go to your “Dashboard” of your site. On the left side of the page, click Media, then Library. The “Media Library” will open.

In the “Media Library”, find the image you want to edit. Click the image once. The “Attachment Details” page will open.

In the “Attachment Details” page, right below the image, click Edit Image. The “Edit Image” menu will open.

Go to your “Edit Page” or “Edit Post” page. On the Edit Page/Post page, click the Image. The “Image options” menu will open.

In the “Image options” menu, click the Edit icon. The “Image Details” page will open.

In the “Image Details” page, right below the image, click Edit Original. The “Edit Image” menu will open.

In the “Edit Image” menu, at the top of the image you want to edit, seven options will be available. From left to right, “Crop”, “Rotate to left”, “Rotate to right”, “Flip horizontally”, “Flip vertically”, “Undo”, and “Redo”.

By default, when opening the “Edit Image” menu, “Crop” will be active. To crop an image, simply click the image and, holding the click, drag the mouse around the area you would like to keep.

To confirm the crop, click the crop icon. The image will refresh to show its new size.

To rotate or flip the image, simply click the icons located at the top of the image. The image will refresh to its new orientation.

On the right side of the page, three more options will be available: “Scale image”, “Image crop”, and “Thumbnail Settings”.

• Scale Image changes the dimensions of the image. Note: It is not recommended to scale to a bigger size than the original dimensions. That could lead to a pixelated image.
• Image crop will show you the aspect ratio that results from the cropping process.
• The thumbnail is a small image preview displayed in the “Media Library” and in featured locations in some themes. Below the “Thumbnail Settings”, the “Apply changes to:” option is available. By default, any changes made through this editing process will be applied to all the image sizes. However, you can apply the changes on different levels.

  

To confirm the changes made, below the image, click Save.
