PDF 2.0 “Errata Collection 2” is now available
The latest PDF 2.0 Errata Collection 2 is a complete update and replacement for the previous no-cost sponsored edition of ISO 32000-2:2020 (PDF 2.0).In April 2023 the PDF Association, sponsored by leading PDF technology companies, Adobe, Apryse, and Foxit, made the ISO standard that defines PDF - ISO 32000-2 - available at no cost.
BUSINESS NOTE
PDF is a modern evolving technology, so corrections and clarifications to PDF’s specification are a fact of life. Implementing errata resolutions ensures PDF software is both correct and interoperable to the greatest degree possible.
BUSINESS NOTE
PDF is a modern evolving technology, so corrections and clarifications to PDF’s specification are a fact of life. Implementing errata resolutions ensures PDF software is both correct and interoperable to the greatest degree possible.
The resulting “ISO 32000-2 bundle” includes PDF’s core specification and four ISO Technical Specification extensions to PDF enabling modern cryptography and digital signature technologies in PDF 2.0. With downloads of these documents now exceeding 30 times ISO’s own sales, the PDF Association and its sponsors have successfully placed the latest and most up-to-date PDF specification into the hands of developers worldwide, helping to improve interoperability and reduce malformed PDF files.
This edition of PDF 2.0 includes Errata Collection 2 and is a complete replacement for the previous no-cost sponsored edition of ISO 32000-2:2020 (PDF 2.0) with the following features and benefits:
- ISO-approved and industry-resolved errata corrections to ISO 32000-2:2020 up to July 20, 2024. A small subset of these errata will also be published in the forthcoming ISO amendment to ISO 32000-2:2020 (PDF 2.0) as these errata corrections are required by ISO/TS 32005 (and thus WTPDF and ISO 14289-2 (PDF/UA-2)) and the dated revisions of ISO 19005-4 (PDF/A-4) and ISO 15930-9 (PDF/X-6).
- 265 total errata corrections implemented as 603 edits (many errata required multiple edits). 324 of the 603 edits (54%) are approved by ISO TC 171 SC 2 WG 8 (the working group responsible for ISO 32000), with the remaining 278 edits approved by the PDF Association’s PDF Technical Working Group (the working group responsible for overseeing PDF in general). The latest resolved errata included in Errata Collection 2 is Issue #449.
- ISO TS 32001 errata correction: Included in the sponsored ISO 32000 bundle, an updated ISO TS 32001 (Extensions to Hash Algorithm Support in ISO 32000-2 (PDF 2.0)) includes an errata correction.
- 17 new / replacement pages. Some errata corrections are unsuited for markup annotations, such as new and corrected illustrations and new tables. These cases are provided as 17 additional pages appended to the PDF, with navigation buttons to and from each appended page.
- Updated Arlington PDF Model. This resource is actively maintained to reflect errata corrections and represents the most up-to-date definition of PDF in machine-readable form.
- Updated Annex L embedded file attachment annotations. These occur on page 947, replacing the previous PDF and spreadsheet data for Annex L.
- Introducing machine-readable EBNF into the PDF specification. The additional errata resolution pages include railroad diagrams and four associated machine-readable EBNF assets as embedded file attachment annotations.
- Navigation enhancements. Page labels now match ISO’s page identifiers, with all new pages bookmarked.
- An instructions page clarifies usage and locations for further updates and information.
You’ll need a capable PDF viewer
Capable PDF viewers are necessary for use of this PDF file, as the errata corrections will otherwise not be visible. Viewers must support, at a minimum, PDF markup and file attachment annotations. Depending on the PDF viewer it may be necessary to enable a “Comment” or similarly-named pane or window in order to make the markup visible.
Each markup includes one or more GitHub Issue numbers referencing the original errata and background discussions preceding its resolution in the respective PDF Association GitHub repository.
Each errata correction indicates its approval body using a status value of either Completed or Accepted. The status is shown using different icons and colors depending on the PDF viewer.

Page labels
Based on feedback from users, the new edition’s Page Labels (ISO 32000-2:2020, 12.4.2) were corrected by the PDF Association such that page navigation now matches the page indicators used on the footer of all ISO pages:
- The Cover pages are labeled “Cover-A” and “Cover-B”.
- The ISO front matter (ISO Foreword and Introduction clauses) uses lowercase Roman numerals from “i” to “xiii” inclusive.
- Clause 1 “Scope”, the main body of the ISO specification, is labeled as page 1; this page and all subsequent ISO pages are numbered with matching Arabic numerals from 1 to 1,003.
- The appended errata pages added for Errata Collection 2 are separately identified as “Errata-n” where n is an Arabic number 1 to 17 inclusive.
When using capable viewers such as those provided by the sponsors, entering these page labels will now navigate to the expected ISO page, avoiding confusion between physical pages and the logical page as indicated in the ISO footer.
