Clean metadata Leave feedback

Sometimes you may need to just remove all or clean metadata properties without applying any filters. The best way to do this is to use the sanitize method.

This example demonstrates how to remove all detected metadata packages/properties.

1. Load a file to clean
2. Call the sanitize method
3. Check the actual number of removed packages/properties
4. Save the changes

basic_usage.CleanMetadata

const metadata = new groupdocs.metadata.Metadata("input.pdf");

    // Remove detected metadata packages
    var affected = metadata.sanitize();
    console.log(`\nProperties removed: ${affected}.`);

    metadata.save("output.pdf");
}

As a result, we get a sanitized version of the original file.

You may easily run the code above and see the feature in action in our GitHub examples:

• GroupDocs.Metadata for .NET examples

• GroupDocs.Metadata for Java examples

• GroupDocs.Metadata for Node.js via Java examples

Along with a full featured Java library we provide simple, but powerful free Apps.
