It\u2019s free, runs on Windows and checks PDFs against PDF\/UA and WCAG standards.<\/p>\n\n\n\n<p>Using PAC is straightforward. Open your PDF, run the test and review the results.

PAC runs only on Windows and is entirely offline. So, no files are uploaded to axes4 or to the internet.<\/p>\n\n\n\n<p>Alongside the automated tests, PAC 2026 offers AI-assisted checks that evaluate semantic structure like headings, paragraphs and tables, things that previously required manual review.<\/p>\n\n\n\n<p>PAC is useful for <a href=\"https:\/\/venngage.com\/blog\/pdf-accessibility-checkers\/\" target=\"_blank\" rel=\"noreferrer noopener\">PDF accessibility audits<\/a> and compliance work, including requirements such as&nbsp;<a href=\"https:\/\/venngage.com\/blog\/understanding-ada-title-ii-updates-the-dojs-new-rule-explained\/\">ADA Title II<\/a>&nbsp;and Section 508.

This means it couldn&#8217;t complete a specific check due to a technical issue with the document. It doesn\u2019t necessarily mean a failed accessibility check.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Go through each checkpoint<\/strong><\/h3>\n\n\n\n<p>Double-click a checkpoint in the summary to open its detailed results. You&#8217;ll see the specific error message along with the page where PAC found the problem.&nbsp;<\/p>\n\n\n\n<p>For example, PAC might flag missing alternative text for a figure. The detailed report helps you locate that figure, but you still need to decide what the appropriate&nbsp;<a href=\"https:\/\/venngage.com\/blog\/image-alt-text\/\" target=\"_blank\" rel=\"noreferrer noopener\">image alt text<\/a>&nbsp;should be and add it using your source document or PDF editor.<\/p>\n\n\n\n<p>Along with all the checkpoints mentioned in the summary and detailed results, PAC also gives two other views to ensure PDF accessibility: screen reader and tag tree.<\/p>\n\n\n\n<ul>\n<li><strong>Screen reader preview&nbsp;<\/strong>shows the order in which assistive technology would read the document. This helps spot problems with the reading order.<\/li>\n\n\n\n<li>The&nbsp;<strong>tag tree<\/strong>&nbsp;shows the structure behind the document, including headings, paragraphs, lists, images and tables. You can use it to check whether the content has been tagged correctly and whether the&nbsp;<strong>heading hierarchy and semantic structure<\/strong>&nbsp;make sense.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Review warnings carefully<\/strong><\/h3>\n\n\n\n<p>Don&#8217;t treat every warning as an automatic failure, though. Some PDF accessibility checks are designed to point you toward potential problems that still need human judgment.&nbsp;<\/p>\n\n\n\n<p>For example, PAC&#8217;s Quality checks can flag whether something looks like a heading, but you still need to decide whether it should actually be a heading and whether it has the right structure.<\/p>\n\n\n\n<p>Treat the PAC Checker report as the starting point for finding accessibility issues, investigate them in the PDF and decide what you need to fix before moving on to a manual review.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Prioritize accessibility fixes<\/strong><\/h3>\n\n\n\n<p>PAC doesn&#8217;t rank accessibility issues by severity, so you&#8217;ll need to decide what to fix first. Here&#8217;s how you should prioritize PDF accessibility fixes:<\/p>\n\n\n\n<ul>\n<li><strong>Missing information:<\/strong>&nbsp;Missing document language, title, tags or alt text for informative images. Fix these first because the information isn&#8217;t available to assistive technology.<\/li>\n\n\n\n<li><strong>Incorrect structure:<\/strong>&nbsp;Incorrect reading order, heading hierarchy, list structure or table headers. The information is there, but it&#8217;s structured incorrectly, which can make it difficult for assistive technology to interpret.<\/li>\n\n\n\n<li><strong>Navigation issues:<\/strong>&nbsp;Missing bookmarks, unclear link structure or other issues that make the document harder to navigate.<\/li>\n\n\n\n<li><strong>Lower-priority findings:<\/strong>&nbsp;Decorative elements, stylistic issues and Quality warnings that don&#8217;t directly affect how the content is accessed.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Do manual checks<\/strong><\/h3>\n\n\n\n<p>PAC can catch a lot of the technical stuff, like missing heading tags, incorrect structure or missing alt text. But it can&#8217;t tell you whether the alt text describes the image correctly or whether the reading order works for someone using a screen reader.&nbsp;<\/p>\n\n\n\n<p>That&#8217;s where you need to do a manual check, too. Review the reading order, alt text and document structure before you publish a PDF.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What are AI-assisted checks in PAC 2026?<\/strong><\/h2>\n\n\n\n<p>PAC 2026 offers AI-assisted checks for PDF accessibility that were traditionally done manually. It can analyze the document&#8217;s semantic structure and identify headings, paragraphs, lists, tables, images, captions, or any other structural element.<\/p>\n\n\n\n<p>For example, PAC can flag a heading that looks like a heading visually but isn&#8217;t tagged as one, or content that appears on the page but has no corresponding tag. The AI looks at the content, formatting, position and context rather than relying on something simple like bold text to identify a heading.<\/p>\n\n\n\n<p>But don&#8217;t treat the AI checks as final. PAC 2026&#8217;s AI checks are supporting information. The AI tab reports warnings rather than errors. While it can point you toward possible semantic problems, you&#8217;ll still need to decide whether the structure is actually correct.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What are the most common accessibility failures in PAC?<\/strong><\/h2>\n\n\n\n<p>Accessibility checkpoint failures, such as missing tags and incorrect reading order, usually happen at the document creation stage. This is more common in PDFs that have visual elements such as images, charts, tables and infographics, which need the right tags, reading order and alt text for assistive technology.<\/p>\n\n\n\n<p>Let\u2019s look at the most common accessibility failures in PAC and why they happen.<\/p>\n\n\n\n<div style=\"overflow: hidden !important;

However, it only helps verify the PDF against PDF\/UA and WCAG standards. It can&#8217;t fix the issues it finds. That can lead to a lot of back and forth: test the PDF, go back to the source document or another tool to fix the issues, export it again and then run another PAC test.<\/p>\n\n\n\n<p>A better approach is to address accessibility while you create the document. Venngage helps you do this with built-in accessibility tools, so you can check things like color contrast, reading order, heading structure and alt text before exporting your PDF. You can then use PAC to check the final document rather than uncovering a long list of issues after export.<\/p>\n\n\n\n<center><a href=\"https:\/\/calendly.com\/bhanu_laul\/call-with-bhanu-from-venngage-a11y?utm_source=blog\" target=\"_blank\" rel=\"noopener\"><button class=\"btn-cta\"><b>START CREATING ACCESSIBLE PDFs WITH VENNGAGE<\/b><\/button><\/a><\/center>&nbsp;\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Frequently asked questions<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. What is PAC used for?<\/strong><\/h3>\n\n\n\n<p>PAC is a free PDF accessibility checker that tests PDFs against PDF\/UA and WCAG requirements. It helps you identify accessibility issues before publishing a PDF.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. How much does PAC cost?<\/strong><\/h3>\n\n\n\n<p>PAC is free to download and use. It\u2019s available as a Windows desktop application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Does PAC fix PDF accessibility issues?<\/strong><\/h3>\n\n\n\n<p>No. PAC identifies accessibility issues but doesn&#8217;t remediate them. You&#8217;ll need to fix the issues in your source document or another PDF tool, then run the test again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Does a passing PAC test mean a PDF is fully accessible?<\/strong><\/h3>\n\n\n\n<p>No. PAC can automate many technical checks, but some accessibility requirements still need human review. You should manually check things such as reading order and whether alt text actually describes the visual content.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Does PAC work on Mac?<\/strong><\/h3>\n\n\n\n<p>No. PAC is currently a Windows-only tool. If you&#8217;re on Mac, you can use axesCheck, the web-based accessibility checker from axes4.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>6. What\u2019s new in PAC 2026?<\/strong><\/h3>\n\n\n\n<p>PAC 2026 introduced AI-assisted checks that can identify potential issues with the semantic structure of a PDF, including headings, paragraphs, lists and tables. These checks complement PAC\u2019s existing automated tests but don&#8217;t replace manual review.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>7. Should I use a design tool or a PDF editor to fix PAC failures?<\/strong><\/h3>\n\n\n\n<p>If the problem is with the document&#8217;s layout, structure, reading order or visual content, it&#8217;s usually better to fix it in the source or design tool and export the PDF again. For issues that only appear after export, a PDF editor can be useful for making targeted fixes.&nbsp;<\/p>\n\n\n\n<p>Ideally, you should build accessibility into the document from the start, then use a tool like PAC to verify the exported PDF.
