How to Fix Image Orientation with EXIF Metadata?

Have you ever opened a photo and found that it appears sideways or upside down, even though it looks correct in another app?

The problem may come from the photo's EXIF Orientation metadata rather than from the image pixels themselves.

Many cameras and smartphones use the EXIF:Orientation tag to tell software how an image should be displayed. If this value is missing or incorrect, a photo may appear with the wrong orientation.

In this guide, we'll show you how to inspect and fix EXIF image orientation on Mac using MetaImage.

What Is the EXIF Orientation Tag?

When you rotate your camera or smartphone to take a portrait photo, the device doesn't always rearrange the image pixels themselves.

Instead, it can store information in the image's metadata indicating how the photo should be displayed.

This information is stored in the EXIF Orientation tag.

Compatible applications read this value and automatically rotate or flip the image when displaying it.

Why Does a Photo Appear Rotated Incorrectly?

Problems can occur when the EXIF Orientation value doesn't correctly describe the orientation of the image data.

This can result in a photo appearing:

• Sideways
• Upside down
• Mirrored
• Correct in one application but incorrectly rotated in another

Different applications may also handle orientation metadata differently, which can explain why the same file doesn't always appear identical everywhere.

How to Fix EXIF Orientation on Mac

MetaImage lets you inspect and edit the EXIF:Orientation tag directly.

Start by opening MetaImage, then drag and drop the image you want to correct into the application.

You can also use the dedicated Open command to select your file.

In this example, the image isn't displayed with the correct orientation.

Edit the EXIF Orientation Tag

You can correct the orientation manually by locating:

EXIF:Orientation

Double-click the tag and select the appropriate orientation value.

Alternatively, MetaImage provides a dedicated command:

Tags → Fix Image Orientation

Once the orientation is correct, save your changes.

EXIF Rotation vs. Rotating Image Pixels

It's useful to understand that changing the EXIF Orientation tag and physically rotating the image pixels are not necessarily the same operation.

EXIF orientation tells compatible software how the existing image data should be displayed. A pixel rotation actually transforms the image data itself.

This distinction explains why orientation problems can sometimes appear when moving photos between different applications, websites, or workflows.

Edit EXIF Metadata with MetaImage

MetaImage is a metadata editor for Mac that lets you inspect and edit EXIF, IPTC, XMP, GPS, dates, camera information, and other photo metadata.

In addition to fixing image orientation, you can use MetaImage to correct dates, edit locations, manage copyright information, and modify other metadata stored with your photos.
