In April 2026, the Pdftools documentation included the following updates:

Added

• Added release notes for the PDF Viewer SDK version 5.15.0 and version 5.15.1 with updated API references.
• Added a new OCR guide category for the Pdftools SDK, including:
  • An overview of the built-in OCR module with processing dimensions, formats, and use cases.
  • A step-by-step OCR a PDF guide with code samples in C#, Java, Python, and C.
  • An OCR best practices page covering performance optimization, thread safety, and resource management.
  • An OCR with the Shell Tool guide for the ocr command added in version 1.12.0.
• Added Java migration guides for moving from Pdftools SDK 1.14 or earlier to 1.15+ and from Toolbox add-on 1.11 or earlier to 1.12+.
• Added a Customer portal documentation page with screenshots covering license keys, maintenance dates, page credits, and product builds.
• Expanded the Pdftools OCR Service Getting started guides with a license key section, a new Set up Pdftools OCR Service with Pdftools SDK section with per-language tabs (C#, Java, Python), and interlinks with the Pdftools SDK OCR guides.
• Documented all available events emitted by the Conversion Service in the Conversion workflow page.
• Added a banner about the deprecation of the legacy My PDF Tools Portal across the documentation.
• Updated the Pdftools SDK OCR best practices with additional code snippets.
• Improved the Pdftools documentation search with a customized DocSearch, page previews, version deduplication, and better local-result boosting.
  

Changed

• Renamed Product kits to Product builds across OCR Service and Conversion Service install and update guides to match the customer portal naming. Updated MSI filenames to a lowercase-hyphen convention (conversion-service-VERSION.msi, ocr-service-VERSION.msi).
• Migrated all code-sample references from the defunct Sample Service download to GitHub:
  • Redesigned the code-samples pages with the new SampleRepoCards component, including per-language icons and a Jupyter/Colab entry that opens notebooks in Google Colab.
  • Normalized the getting-started intros around a clone-and-navigate workflow.
  • Added a temporary code-samples-unavailable banner and admonitions to the legacy code-samples pages.
• Audited and aligned Pdftools SDK guide code snippets in guides category (archive, assemble, sign, secure, validate).
• Updated the Conversion Service Office conversion guide to clarify that Microsoft Office 2024 is the latest supported version, and removed mentions of Office 2019, which is no longer supported.
• Removed all references to the legacy My PDF Tools Portal (my.pdf-tools.com) and the intermediate “crossroad” pages, after the legacy portal was decommissioned. All flows point directly to portal.pdf-tools.com.
• Removed the beta label from the PDF Viewer SDK version 5 documentation.
• Reordered the Conversion Service workflow items alphabetically in the sidebar (PDF/A entries are sorted 1, 2, 3 instead of 2, 3, 1).
• Updated the documentation portal to Docusaurus version 3.10.0 in preparation for Docusaurus version 4, fixing all build errors and warnings.

Fixed

• Dropped physical and directional language (“scroll”, “left-hand side”, “right-hand side”) across the documentation according to general accessibility guidelines.
• Fixed an invalid syntax issue in the Conversion Service openapi.yaml specification.
• Updated dependencies for security and stability, including marked, axios, protobufjs, posthog-js, and docusaurus-plugin-llms.
