Clean metadata
Remove all recognized metadata properties from a file
Sometimes you may need to just remove all 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.
- Load a file to clean
- Call the sanitize method
- Check the actual number of removed packages/properties
- Save the changes
basic_usage.CleanMetadata
// Constants.InputPdf is an absolute or relative path to your document. Ex: @"C:\Docs\source.pdf"
try (Metadata metadata = new Metadata(Constants.InputPdf)) {
// Remove detected metadata packages
int affected = metadata.sanitize();
System.out.println(String.format("Properties removed: %s", affected));
metadata.save(Constants.OutputPdf);
}
As a result, we get a sanitized version of the original file.
