**Metapho** is a simple and clean viewer for photo metadata such as date, file name, size, camera model, shutter speed, and location.

On iOS and macOS, you can remove image metadata without using any third-party apps by creating a [**shortcut**](https://apps.apple.com/app/id915249334) for this purpose. Here is an example shortcut you can download to use as is:

[:material-tag-minus: Clean Image Metadata](https://icloud.com/shortcuts/fb774ddb7b5b4296871776c67ac0fff9){ .md-button }

</details>

</div>
You can also use it as a model for your own shortcut; just make sure that the **Preserve Metadata** option under the **Convert** action is unchecked. Once added, you can access the shortcut in the share sheet that appears when you select the :octicons-share-24: Share button. You can select multiple images and invoke the shortcut to remove their metadata all at once.

## Command-line
This shortcut removes metadata such as location, device model, lens model, and other camera information. It also sets the image creation date to the time the shortcut was used.
