# Description of Changes Adds a PDF/UA converter, an accessibility report, and PDF/A conformance level A. **New: `POST /api/v1/convert/pdf/ua`** (Convert tool, "PDF/UA" target). Tags an untagged PDF, marks decorative content as artifacts, embeds missing fonts and applies the document-level PDF/UA requirements (title, language, tab order, form-field descriptions), then validates with veraPDF. The `pdfuaid` declaration is written only if validation passes, so a returned file never claims more than it delivers; response headers report whether it was declared, how many checks still fail and how many images still need a description. **New: `POST /api/v1/security/accessibility-report`.** Reports what fails, what the converter can fix on its own, what needs a person, and lists the figures needing a description with the keys the conversion accepts back. Read-only; does not modify the file. Capped at 100 MB / 2000 pages and weighted `LARGE_WEIGHT`, since it runs a full veraPDF pass plus the converter's layout analysis over every page. **PDF/A level A.** `pdfa-1a`, `pdfa-2a` and `pdfa-3a` output formats on the existing `/api/v1/convert/pdf/pdfa` endpoint. Level A is level B plus tagging, so the document is tagged after Ghostscript (which discards any structure tree it is given) and the level A claim is written only if veraPDF agrees. Optional `pdfUa=true` additionally declares PDF/UA alongside PDF/A, again only if it validates. Honesty rules the implementation holds to: - **Never claim a level that was not reached.** If tagging fails, the file is returned at level B and is named `_PDFA-2b.pdf`, not `_PDFA-2a.pdf`. With `strict=true` the request fails outright rather than returning a level B file against a level A request, and a level B pass no longer satisfies a strict level A request. - **Never relabel a document's language.** The requested language (default `en-GB`) is applied only when the document declares none; a French PDF stays French unless the caller sets `overrideLanguage`, and ignoring a requested language is reported as a warning. - **Never invent alternative text.** Descriptions come from the caller. The Convert panel can list the images needing one (via the report endpoint) and send them back per figure; any image left undescribed blocks the conformance claim rather than being papered over. - **Never certify hidden content.** Marking images decorative, or suppressing text that could not be tagged reliably, withdraws the claim instead of passing the checker by hiding content. PDF/UA-1 and PDF/UA-2 are both offered; UA-2 raises the file to PDF 2.0 and namespaces the structure tree, and its test asserts conformance rather than merely reporting it. Convert steps saved in Automations/Pipelines round-trip their PDF/UA settings (profile, language, override, title, font embedding, descriptions). --- ## Checklist ### General - [ ] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [ ] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [ ] I have performed a self-review of my own code - [ ] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### Translations (if applicable) - [ ] I ran [`scripts/counter_translation.py`](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/docs/counter_translation.md) ### UI Changes (if applicable) - [ ] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [ ] I have run `task check` to verify linters, typechecks, and tests pass - [ ] I have tested my changes locally. Refer to the [Testing Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/DeveloperGuide.md#7-testing) for more details.
