Summary: This article introduces a new Apryse code sample that leverages LangChain and LLMs directly within WebViewer to automatically detect PII and create redaction annotations to streamline the document security workflow. By integrating AI-powered detection, users can efficiently identify sensitive data while retaining necessary human oversight for final redaction approval.

Summary: This article demonstrates how to create a highly intuitive tool for generating GoToR links by using two side-by-side instances of Apryse WebViewer. By utilizing a custom button in a dual-viewer setup, developers can enable users to select text and link it directly to a document's current page in a view-only pane, eliminating the need for manual metadata entry.

Summary: Apryse WebViewer offers extensive functionality but has a large default file size that can be significantly reduced using a built-in, automated "Optimize" script. This article details how to use the script to remove unused components, decreasing the deployment size and optimizing the library for specific project needs.

Summary: This blog details three approaches to PDF signing (visual, e-signature with audit trails, and cryptographic digital signatures) emphasizing the need for a secure client-server split to avoid exposing private keys. It covers production certificate management for compliance with standards like ESIGN and eIDAS, ensuring long-term validation (LTV) and document integrity. Also included is sample code for implementing digital signatures using Apryse SDKs.

Summary: Protecting sensitive data in industries like healthcare, law, and insurance is vital for compliance and risk reduction. This article demonstrates how to use the Apryse SDK to automate the detection of sensitive content inside a PDF within the browser. You will learn how to automatically scan and identify sensitive keywords, names, and addresses upon document load, programmatically generate redaction annotations using text coordinates (quads), and customize redaction styles by adding descriptive overlay text like replacing a name with "Witness A".

Summary: Adding measurement capabilities to a PDF viewer app requires accurate canvas scaling, calibration interfaces, and proper ISO-compliant annotation storage. This article walks through the architectural requirements of embedding PDF measurement tools, compares the four main implementation paths, and provides concrete code examples for both turnkey SDKs and building from scratch using PDF.js.
