PDF ADA Accessibility Editor

Instructions for use (click to expand)

Use Build New PDF to compose a simple tagged document from sections: document title and metadata in the left column, content sections in the center, and a live preview on the right.
Under Section content, choose Paragraphs, Bulleted list, or Numbered list. Paragraphs preserve line breaks (blank line = new paragraph) and can include pasted Word-style bullets or numbers in the same block (indent nested rows with tab or two spaces per level). Use the Link button or [link url="https://…"]descriptive text[/link] for hyperlinks (write where the link goes in the visible text, not “click here”). In Numbered list mode, set Numbered list starts at for the first top-level number; nested rows use a./b., then i./ii., then 1) markers. List-only mode uses one item per line.
Drag sections by the grip control to reorder. Use Image max width and Image alignment to match figures in both the preview and the exported PDF. Click View full (100%) or the preview area to open the document at actual size (100%); scroll vertically when there are multiple pages. The sidebar preview stays scaled to fit the column.
Set page margins, fonts, and line spacing under Page layout & typography, then use Build and Export PDF to download your tagged US Letter PDF.

WCAG scope and export notes (click to expand)

When a PDF is web content (download link, button, or embedded viewer on your site), WCAG 2.1 AA applies to both the surrounding HTML/CSS (link purpose, focus, labels for controls that open the PDF, keyboard use, errors in custom viewers) and the accessibility of the PDF itself (real text, logical reading order, structure for headings and images, sufficient contrast, forms when present). W3C publishes PDF-specific guidance and techniques for document accessibility alongside the general WCAG criteria.

Exports apply WCAG-oriented PDF settings (document title shown in the viewer window where supported, catalog language, keywords, XMP PDF/UA part declaration, logical structure tree, tagged highlights). Full WCAG 2.1 Level AA for PDF-as-web-content still depends on your HTML (links, embedding, keyboard use), document content (contrast, tables, scans/OCR), and verification with your checklist or tools such as Acrobat’s accessibility checks or PAC—this app does not certify conformance.

Build New Accessible PDF

US Letter (8.5 × 11 in) with margins you choose below. Paragraphs preserve line breaks. Inline emphasis: [b]…[/b], [i]…[/i], [u]…[/u]; accessible links: [link url="https://…"]link text[/link] (use descriptive link text, not “click here”) in body, headings, and list lines. Lists export as nested L / LI / LBody (indent with two leading spaces or one tab per sub-level). In Numbered list mode, set the starting number for top-level rows; nested rows use a., b., then i., ii., then 1) styles. Figures need alt text (WCAG-oriented).

Include Accessibility Export Manifest in the PDF

Uncheck to omit the tagged manifest section at the end. Your document still exports with StructTreeRoot, MarkInfo, and tagged body content (headings, lists, paragraphs).

Print visible alt caption under images

When off, images still export with Figure tags and real /Alt text; only the extra body line (Image alt text: …) is omitted.

Content Sections

Drag a section by the grip (left) to reorder. The live preview updates as you type. Image width is a percentage of the text column; use Image alignment for left/center/right independent of body text when you want.

Upload and Remediate

Metadata, tags, and export. Page previews are on the right. Save Tagged PDF keeps the original page text as-is (this tool does not reflow or repair broken spacing in the source file); review captured tag text and fix the authoring document if the text layer is wrong.

Existing PDF file

Draw a rectangle on a page preview first. Then set the tag and text below and click Save highlight. Tag consecutive regions as List item (in reading order). Set List nesting level (0 = main list, 1 = sub-list, 2 = sub-sub-list, …) so export builds nested L / LI / LBody trees in the PDF.

Remediation notes

Include remediation summary page

Uncheck to download the tagged PDF only, without the extra “Accessibility Remediation Summary” page at the end.

Include Accessibility Export Manifest in the PDF

Uncheck to omit the tagged manifest (H2/P) after the remediation summary or on its own page. Tagged highlights and structure for your document are unchanged.

Saved tag manifest (inspectable)

PDF page previews

After you choose a file, previews load here. Drag to draw a highlight, then use the panel on the left to choose the tag, review or edit text, and save. Use Tab / Shift+Tab to move through each tagged region on the page previews (and Enter or Space to open the editor).
