Version 5

The following sections provide updates in version 5 of the Conversion Service.

5.7

Added

• As of this update, you can convert WebP images to PDFs.

• You can now export word track changes (redlining) to PDF. For more details, review Configure conversion of redlined Microsoft Word documents.

  

• Previously, you could only skip creating the table of contents in the Dossier workflow. As of this update, the Conversion Service Configurator lets you also skip the creation of outlines (bookmarks) in the Dossier workflow. To skip the outline creation, go to the Dossier workflow configuration and disable the Outline (Bookmarks) toggle.

  

  When the previously described Outline (Bookmarks) option is enabled, the Outline (Bookmarks) configuration section includes the Document Bookmark toggle. If you disable this toggle, bookmarks from various files that are merged into a dossier are no longer nested as children but are all included at the same level.

  

Changed

• With this update, the Troubleshooting tab of the Conversion Service Configurator displays issues detected in profile and connector configuration validation.
• Previously, you could accidentally install the Conversion Service Client on a machine where the Conversion Service was already installed, causing the service to malfunction. As of this release, you can no longer install the Conversion Service Client when the Conversion Service is already installed on the same machine.

5.6

Added

• You can now configure the default address of the Connector Service. For more details, review Connector service host address section.

Changed

• Previously, the Conversion Service Configurator included separate toggles for Add Outlines and Hide Outlines. This feature is available in the Archive PDF/A-1, Archive PDF/A-2, and Archive PDF/A-3 workflows. With this update, the previously separate toggles are now moved into one dropdown menu with the following three options: Display, Hide, and Remove

Fixed

• As of this release, the conversion of HTML, XML, MSG, and EML files is improved.

5.5

Added

• A new welcome window is displayed when you open the Conversion Service Configurator. The welcome window links to the Getting Started documentation, and you can disable it for the next sessions.
  
• With this release, you can set which files attached to emails are skipped during conversion. For more information, review the following sections of the Email connectors documentation:
  • Watched Mailbox (IMAP) Settings
  • Watched Mailbox (Exchange Online) Settings
  

Changed

• With this release, the Pdftools no longer supports Microsoft Office 2016 and Windows Server 2016 with the Conversion Service. You can still utilize the Conversion Service on Windows Server 2016 and use Microsoft Office 2016 for file conversion. However, Pdftools doesn't provide technical support for new customers who use the mentioned versions.

5.4

Added

• Support HTTPS communication for REST input JSON and REST input plain HTTP connectors. For details how to activate the HTTPS communication, review HTTPS documentation.
• You can now convert HTML files containing multimedia elements that are being removed during file conversion. Previously, attempting to convert HTML files with elements such as iframes, audio, or video resulted in an error. With this update, you can set HTML Multimedia Removed in the Warnings section of the profile configuration in the Conversion Service Configurator. As a result, you can skip multimedia elements from HTML files using the described configuration.
• Set the Allow Scaling option for Text Stamps to ensure that the Conversion Service is not adding the stamp outside of the page boundaries. For more information, review Configure stamping documentation.
• With this release, you can specify which files the Watched Folder connector skips using glob patterns. For more information, review Configuration options in the Watched Folder connector docs.
• The Conversion Service adds outlines (bookmarks) to converted PDF files by default. Previously, there was no option to disable or hide the bookmarks. As of this update, options to remove or hide bookmarks are available for the following workflows: Archive PDF/A-1, Archive PDF/A-2, Archive PDF/A-3.
  • To remove the bookmarks: Disable the Add Outlines toggle in Conversion Settings > Viewer Preferences configuration section.
  • To hide the bookmarks: Enable the Hide Outlines toggle in Conversion Settings > Viewer Preferences configuration section. As a result, the bookmarks are still accessible in your PDF viewer but are hidden by default.
• As of this release, you can now convert hidden attachments in emails (attachments that start with a dot). To use this feature, enable the Include Hidden Attachments toggle in Email Settings of the Configurator.
• You can now remove format protection in the Office for Web configuration. Enable the Remove Excel Format Protection toggle in Office Conversion > Office For Web Settings configuration section.

Fixed

• Under certain circumstances, conversion of .MSG file to any PDF or PDF/A format resulted in images being replaced by placeholders in the output PDF files. This issue is now fixed and all images are displayed correctly.
• Before this update, while using the Dossier Workflow, merging PDF with form fields of the same name as the PDF file overwrote the form fields. This issue is now fixed and all PDFs are displayed properly.

5.3

Added

• Proxy settings are now extended. Email-related connectors can now use a defined proxy URL if you enable it in the Configurator. Review Proxy configuration documentation for more information.
• With this release, the Configurator introduces a Troubleshooting tab that offers solutions to detected issues. In this version, the troubleshooting functionality checks if the recommended Microsoft Defender rules are set. This feature will be expanded to include additional checks.
  
• Profile option Allow Resize PDF in Document Settings configuration section. This option resizes the page using the value set in the Default Page Size option configured in the Document Settings section. If you disable this option, the original page size of the document is used.
• Before this update, you could only convert email subject fields to titles during email to PDF/A conversion. With this update, you can now set the Use Subject As Subject configuration option in the Email Settings section of the Configurator that converts the subject of an email as a title and as a subject of the PDF file.
  

Fixed

• Previously, when configuring the Child Removed to error in the Warnings section of the profile settings, the Conversion Service prompted you with a warning instead of an error when removing the child files (files attached to emails or other document formats). With this update, the issue is fixed, and the configuration results in an appropriate error prompt when the Conversion Service removes child files in the described configuration.
