A Reliable Java PDF Library

A powerful solution for batch processing, manipulating, and editing PDF documents.

Trusted By

Redaction

Permanently Remove Sensitive, Confidential, or Privileged Information from PDFs

Search for personally identifiable information and redact it automatically or stage it for redaction at a later point. You can use out-of-the-box presets or create custom search patterns using regular expressions. Frequently used in e-discovery, e-disclosure, legal, financial, healthcare, and government applications.

Batch redaction of PDFs using built-in presets

Secure and irrecoverable removal of PDF text and images
Ensure compliance with GDPR, HIPAA, and other privacy laws
Rapidly process redactions across large batches of PDFs

Document Editor

Merge, Add/Remove, Split, and Rotate Pages

Access powerful low-level controls for merging PDFs, adding or deleting pages, appending cover sheets, and rotating pages. Assemble multiple documents into a single unified PDF for easier distribution and recordkeeping. Ensure document uniformity across all business processes.

Annotation Editing

Import and Export Annotations to XFDF and Instant JSON

Extract annotation data from large volumes of PDF documents for exporting to a database. Optimize for speed and network traffic by transmitting only the user’s edited changes via XFDF or Instant JSON.

XFDF and Instant JSON data imported into PDF

Use our proprietary Instant JSON format or XFDF to import and export large amounts of annotation data
Permanently apply annotations by batch-flattening all changes to prevent further revision
Extract user data from PDF form fields in XFDF

PDF Rendering

High-Fidelity Rendering of PDF Documents

Access the same powerful rasterizing engine that annually processes billions of documents for our customers worldwide. Easily integrate accurate document and page rendering into your existing workflows. Render large batches of PDFs to commonly used image file types.

PDF rendering with documents saved as JPG, PNG, and WEBP

Render and save PDF documents as JPG, PNG, or WEBP
Rapidly convert PDF documents or individual pages to high-fidelity bitmaps of any size
Ensure precise file structure retention, with text layout and tables appearing exactly as shown in the original PDF

Form Filling

Read and Write Form Fields with an Easy-to-Use API

Our Forms component enables you to programmatically read and write form values. Simply build a model of your data and call a single API to fill out forms.

Integration

Using PSPDFKit for Java

PSPDFKit can be integrated with just a few lines of code, and it comes with a rich API, which allows for complete customization.

Java
Copy// Initialize PSPDFKit with your activation key.
PSPDFKit.initialize("YOUR_LICENSE_KEY_GOES_HERE");

// Open a document to work on.
File file = new File("assets/default.pdf");
PdfDocument document = new PdfDocument(new FileDataProvider(file));

// Add a new stamp annotation.
JSONObject jsonObject = new JSONObject();
jsonObject.put("bbox", new float[]{0, 0, 100, 50});
jsonObject.put("pageIndex", 0);
jsonObject.put("type", "pspdfkit/stamp");
jsonObject.put("stampType", "Approved");
jsonObject.put("opacity", 1);
jsonObject.put("v", 1);
document.getAnnotationProvider().addAnnotationJson(jsonObject);

// Export the changes to Instant Document JSON.
File jsonFile = new File("out/instantOutput.json");
if (jsonFile.createNewFile()) {
    document.exportDocumentJson(new FileDataProvider(jsonFile));
}

// Render the first page and save to a PNG.
BufferedImage image = document.getPage(0).renderPage();
File pngfile = new File("out/test.png");
boolean success = ImageIO.write(image, "png", pngfile);
