Release notes

What changed in each release of the EVO HTML to PDF Converter and the EvoPdf library. The current version is listed on the download page.

New Features in EvoPdf Next v15.0

  • The HTML to PDF and HTML to Image converters render with Chromium 154, the current engine at the time of the release. This major version works with version 15 license keys: the same HTML to PDF key is used by EvoPdf Next and EvoPdf Classic, while the Word, Excel, RTF and Markdown converters work with an EvoPdf Toolkit key for version 15
  • Applications written for EvoPdf Classic run on EvoPdf Next without changes to their PDF code: the EvoPdf.HtmlToPdf.Windows, EvoPdf.HtmlToPdf.Linux and EvoPdf.HtmlToPdf.MacOS NuGet packages, with their .Arm64 variants, keep the API of the Classic library and render with the Chromium engine of EvoPdf Next, so the same application runs on Windows, Linux and macOS and directly in Azure App Service for Windows, without the server and client components the Classic library needed there. The Classic converter also gives access to the EvoPdf Next converter it uses (NextConverterCreated), which brings the features of EvoPdf Next to the existing code, such as PDF/UA-1 and PDF/UA-2 documents and electronic invoices. The Classic demo application on the Next engine can be downloaded ready to run: it is the Classic demo application written with the Classic API, configured to run on the platform packages, with a PDF standard option on the Getting Started page and a page that creates electronic invoices. See the Classic to Next migration page and the documentation topic
  • HTML pages are requested through a proxy server when ProxyOptions is set: HTTP or SOCKS5, with credentials for HTTP proxies and a list of hosts that bypass the proxy. See the documentation topic
  • PdfEditor adds, inserts, moves, rotates and removes the pages of an existing document and reports the size and rotation of each page; PdfSplit.RemovePages returns a document without the given page ranges (Split PDF Documents demo). See the Edit PDF Pages demo and the documentation topic
  • Gradient fills for shapes in the Core PDF API. See the Gradient Fills demo and the documentation topic
  • The Core PDF API reads and edits the bookmarks of existing documents, sets the action run when a document opens, draws pages of other PDF documents in the pages of a new or existing document, under or over the content and controls high resolution printing in the document permissions
  • Word to PDF: the fonts embedded in the document and font files added by the application are used in the PDF, with fallback fonts for the scripts the document fonts do not cover (demo, documentation); the running headers and footers of the document are rendered on the PDF pages, with their page numbers (demo, documentation); the document outline, custom bookmarks, the open action and file attachments are set on the generated PDF (demo, documentation); electronic invoices are produced from Word documents (demo, documentation)
  • Word, Excel, RTF and Markdown documents are added to the pages of a PDF document created with the Core PDF API, as elements placed at a given position, with their own zoom, continuing on the pages that follow: Word, Excel, RTF and Markdown demos
  • RTF to PDF renders the headers and footers of the RTF document on the PDF pages, with their page numbers. See the demo and the documentation topic
  • PdfRedactor removes text, images and vector content from the pages of existing documents: the matches of a text or of a regular expression, personal data such as email addresses, phone numbers or card numbers, rectangular areas and whole pages. It also redacts the areas marked for redaction during a review in a PDF viewer and can save its own marks for review before any content is removed. The removed content is taken out of the file, not covered. See the Redact Text and Personal Data, Redact Areas and Pages and Apply Redaction Annotations demos and the documentation topic
  • HTML to PDF: PdfFormOptions.ExcludedFieldsSelector leaves the HTML controls matching a CSS selector out of the generated PDF form (documentation) and PdfDocumentOptions.FirstPageTopMargin starts the content of the first page lower than on the other pages (documentation). Core PDF API: PdfDocument.TableOfContents inserts a table of contents built from the headings of the HTML content added to a document created from code (documentation) and PdfImageElement.KeepAspectRatio set to false stretches an image to the given width and height (documentation)
  • HTML to PDF: the elements of each bookmark level and of each table of contents level are selected with CSS selectors, one selector per level, set in PdfDocumentOptions.OutlineHeadingSelectors and TableOfContentsOptions.HeadingSelectors, so the bookmarks and the table of contents can list different elements; the Core PDF API has the same selectors in PdfDocumentTableOfContents.HeadingSelectors. See the Auto Create Hierarchical Bookmarks and Table of Contents demos and the documentation of the bookmarks and of the table of contents
  • The HTML to Image converter has a Resolution option in dots per inch: a value above 96 produces a sharper image of the same layout, for print or for high density screens and the PNG and JPEG files record the resolution. See the HTML to Image demo and the documentation topic
  • PdfEditor.AddHtml renders HTML content in the pages of an existing document, as text and vector graphics that continue on the next pages. See the Add HTML to Existing PDF demo and the documentation topic
  • A text added to an existing document with PdfEditor can continue on pages inserted after the page where it starts (PdfTextElement.InsertContinuationPages), with its own top and bottom margins on those pages (ContinuationTopMargin, ContinuationBottomMargin). See the Add Text to Existing PDF demo and the documentation topic

New Features in EvoPdf Next v14.86

  • Digital signatures: PAdES signatures at all the levels, up to long-term validation, signed with a PFX file, with a certificate from the Windows certificate store, a smartcard or a USB token, or through an external signing service such as a hardware security module or a cloud key service. The Digital Signatures demo and the documentation topic show the options
  • PdfEditor signs existing PDF documents and keeps the signatures already in the document valid. It also adds signature fields to a document, one for each signer, signed later by field name and placed where the HTML page shows the signatures. See the Digitally Sign Existing PDF demo, the Add Signature Fields from HTML Elements demo and the documentation
  • Electronic invoices: the HTML to PDF converter and the Core PDF API produce standard electronic invoices, a PDF/A-3 document with the invoice data embedded, accessible with PDF/UA-1. The Create Electronic Invoices demo and the documentation topic show the options
  • The documentation has deployment guides with complete examples for Azure App Service, Azure Functions, Azure Container Apps and AKS, AWS Elastic Beanstalk, Lambda, Amazon ECS and EKS, Google Cloud Run and GKE and Docker on Linux and Windows; the Azure, AWS and Google Cloud pages summarize them

New Features in EvoPdf Next v14.84

  • The default rendering mode of the HTML to PDF converter is now FitBrowserWindowToPage: a fixed A4 page with the 1024 pixel browser window scaled to fit it, the same output the Classic converter gives by default. Code moving from Classic to Next keeps the look of its PDF documents with no page settings. The Classic to Next migration guide and the migration topic of the documentation describe the move
  • The previous default, with the PDF page as wide as the browser window and the HTML drawn without scaling, is available as PageWidthFromBrowserWindow
  • New rendering modes were added as ready-made recipes for the converter options: LayoutAtPageWidth for templates designed for a paper size, PrintLikeChrome for the output of the Chrome browser and SinglePageOfWidth for receipts on narrow paper. They are described in HTML to PDF Page Setup and Scaling; the Getting Started demo lets you compare the page layouts on any URL

New Features in EvoPdf Next v14.60.3

  • Convert HTML to PDF/UA-compliant tagged documents for accessibility (PDF/UA-1 and PDF/UA-2 are currently supported)
  • Convert HTML to PDF/A-compliant documents for archiving (PDF/A-2a, PDF/A-2b, PDF/A-3a, PDF/A-3b, PDF/A-3u, PDF/A-4 and PDF/A-4f are currently supported)
  • Create PDF/UA- and PDF/A-compliant documents containing text, images, graphics and attachments
  • Convert HTML form controls into interactive PDF form fields while preserving submit and reset button functionality
  • Allow rotation of HTML stamps applied to existing PDF documents or to PDFs generated from HTML
