Tue, 09 Jun 2026 00:00:00 +0000

Clear PDF metadata

Use this workflow when you need to remove stored document information before sharing or archiving a PDF.

Steps

Create a PdfFileInfo object for the input PDF.
Call clearInfo() to remove document metadata.
Save the result to a new file with save().
Close the PdfFileInfo instance.

Java example

public static void clearPdfMetadata(Path inputFile, Path outputFile) {
    PdfFileInfo pdfInfo = new PdfFileInfo(inputFile.toString());
    pdfInfo.clearInfo();
    pdfInfo.save(outputFile.toString());
    pdfInfo.close();
}

Tue, 09 Jun 2026 00:00:00 +0000

Get PDF metadata

This example reads standard document information, file status flags, and a custom metadata key.

Steps

Create a PdfFileInfo object for the source PDF.
Read the standard metadata fields such as subject, title, keywords, and creator.
Inspect file state flags such as whether the file is valid, encrypted, password protected, or a portfolio.
Read a custom metadata value with getMetaInfo.
Close the PdfFileInfo instance.

Java example

public static void getPdfMetadata(Path inputFile) {
    PdfFileInfo pdfInfo = new PdfFileInfo(inputFile.toString());
    System.out.println("Subject: " + pdfInfo.getSubject());
    System.out.println("Title: " + pdfInfo.getTitle());
    System.out.println("Keywords: " + pdfInfo.getKeywords());
    System.out.println("Creator: " + pdfInfo.getCreator());
    System.out.println("Creation Date: " + pdfInfo.getCreationDate());
    System.out.println("Modification Date: " + pdfInfo.getModDate());
    System.out.println("Is Valid PDF: " + pdfInfo.isPdfFile());
    System.out.println("Is Encrypted: " + pdfInfo.isEncrypted());
    System.out.println("Has Open Password: " + pdfInfo.hasOpenPassword());
    System.out.println("Has Edit Password: " + pdfInfo.hasEditPassword());
    System.out.println("Is Portfolio: " + pdfInfo.hasCollection());
    String reviewer = pdfInfo.getMetaInfo("Reviewer");
    System.out.println("Reviewer: " + (reviewer == null || reviewer.isBlank() ? "No Reviewer metadata found." : reviewer));
    pdfInfo.close();
}

Java: Save Metadata with XMP

Tue, 09 Jun 2026 00:00:00 +0000

Save metadata with XMP

Use this workflow when you need the updated document information to be stored in XMP format.

Steps

Create a PdfFileInfo object for the source PDF.
Set the metadata fields you want to update, such as subject, title, keywords, and creator.
Call saveNewInfoWithXmp() with the output file path.
Close the PdfFileInfo instance.

Java example

public static void saveInfoWithXmp(Path inputFile, Path outputFile) {
    PdfFileInfo pdfInfo = new PdfFileInfo(inputFile.toString());
    pdfInfo.setSubject("Aspose PDF for Java");
    pdfInfo.setTitle("Aspose PDF for Java");
    pdfInfo.setKeywords("Aspose, PDF, Java");
    pdfInfo.setCreator("Aspose Team");
    pdfInfo.saveNewInfoWithXmp(outputFile.toString());
    pdfInfo.close();
}

Java: Set PDF Metadata

Tue, 09 Jun 2026 00:00:00 +0000

Set PDF metadata

Use this workflow when you need to normalize or enrich document information before saving the PDF.

Steps

Create a PdfFileInfo object for the source PDF.
Set the standard metadata fields you want to update.
Add any custom metadata with setMetaInfo.
Save the updated document with save().
Close the PdfFileInfo instance.

Java example

public static void setPdfMetadata(Path inputFile, Path outputFile) {
    PdfFileInfo pdfInfo = new PdfFileInfo(inputFile.toString());
    pdfInfo.setSubject("Aspose PDF for Java");
    pdfInfo.setTitle("Aspose PDF for Java");
    pdfInfo.setKeywords("Aspose, PDF, Java");
    pdfInfo.setCreator("Aspose Team");
    pdfInfo.setMetaInfo("CustomKey", "CustomValue");
    pdfInfo.save(outputFile.toString());
    pdfInfo.close();
}
