How can I remove metadata from images?

I have encountered the same problem as you before, and I want to find a way to remove metadata from images, especially photos taken with mobile phones, where the location and device information are hidden.
In fact, there are several ways to do it yourself without relying on third-party tools! Share three simple methods with you:

✅ Method 1: Use the built-in function of Windows to batch clear

Select the image → right click → properties → details → click "Delete properties and personal information".

It supports selecting multiple images to process together, and can basically remove metadata from images, but some hidden information may not be deleted thoroughly enough.

✅ Method 2: Use the preview tool that comes with macOS

On Mac, open the image → Export → Uncheck "Include location information".

In this way, the new image exported will not include GPS, and simply clean up most of it, which is a semi-automatic way to remove metadata from images.

✅ Method 3: Use the command line ExifTool (built-in or installable)

If you have brew (Mac) or choco (Windows), you can quickly install exiftool.

It can be done with one command, for example, exiftool -all= *.jpg can remove metadata from images in batches, completely and cleanly without leaving any traces!

To summarize: if you only delete a few photos occasionally, just use the system's built-in function;
If you want to do it in batches, thoroughly and professionally, use the exiftool command line, which is super fast and super clean!
