Exiftool

Remove all Metadata like camera model, lens, aperture etc from Image metadata.

1. Install ExifTool

• Open Terminal and paste the following command to install Homebrew:

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

• Install ExifTool: Once Homebrew is installed, use it to install ExifTool by running:

  brew install exiftool

2. Strip All Metadata

To completely strip all metadata from the images, use the -all= option, which removes all metadata tags from the files.

1. Open Terminal.

2. Navigate to the directory containing your images. For example:

   cd ~/Desktop/images

3. Run ExifTool to strip all metadata: Use the following command to remove all metadata from all JPEG images in the directory:

   exiftool -all= -overwrite_original -r .

   Here is what each parameter does:

   • -all=: Removes all metadata tags.

   • -overwrite_original: Overwrites the original files without creating backup copies.

   • -r: Processes directories recursively.

   • .: Specifies the current directory.

3. Verify the Changes

After running the command, you can verify that the metadata has been removed by checking the properties of one of the images:

exiftool yourimage.jpg

Replace yourimage.jpg with the name of one of your JPEG files. ExifTool should return minimal information, indicating that most, if not all, metadata has been removed.

Additional Step: Remove Specific Tags Only (Optional)

You can specify which tags to remove if you need to keep some metadata while removing others. Here’s an example that removes common camera-related metadata and other specific tags:

exiftool -Model= -Make= -FocalLength= -ExposureTime= -FNumber= -ISO= -ApertureValue= -ShutterSpeedValue= -WhiteBalance= -ExposureBiasValue= -Flash= -ProfileDescription= -ColorSpace= -ImageWidth= -ImageHeight= -ResolutionUnit= -XResolution= -YResolution= -overwrite_original -r .

Use this command if you want to selectively remove specific metadata fields while retaining others.
