# 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.

Frontend
All frontend commands are run from the repository root using Task:
task frontend:dev— start Vite dev server (localhost:5173)task frontend:build— production buildtask frontend:test— run teststask frontend:test:watch— run tests in watch modetask frontend:lint— run lintingtask frontend:typecheck— run TypeScript type checkingtask frontend:check— run typecheck + lint + testtask frontend:install— install npm dependencies
For desktop app development, see the Tauri section below.
Layout
frontend/ is a workspace containing one or more apps. Today it holds the
PDF editor under frontend/editor/; new apps (the developer portal, etc.)
will sit alongside it as siblings. Shared tooling — package.json, node_modules,
.storybook/, oxlint, Prettier — lives at frontend/ so every app installs
once and lints with the same config.
Environment Variables
The editor's environment variables live in committed .env files at
frontend/editor/:
.env— used by all builds (core, proprietary, and as the base for desktop/SaaS).env.desktop— additional vars loaded in desktop (Tauri) mode.env.saas— additional vars loaded in SaaS mode
These files contain non-secret defaults and are checked into Git, so most dev work needs no further setup.
To override values locally (API keys, machine-specific settings), create an uncommitted sibling editor/.env.local / editor/.env.desktop.local / editor/.env.saas.local. Vite automatically layers these on top of the committed files.
Docker Setup
For Docker deployments and configuration, see the Docker README.
Tauri
All desktop tasks are available via Task. From the root of the repo:
Dev
task desktop:dev
This ensures the JLink runtime and backend JAR exist (skipping if already built), then starts Tauri in dev mode.
Build
task desktop:build
This does a full clean rebuild of the backend JAR and JLink runtime, then builds the Tauri app for production.
Platform-specific dev builds are also available:
task desktop:build:dev # No bundling
task desktop:build:dev:mac # macOS .app bundle
task desktop:build:dev:windows # Windows NSIS installer
task desktop:build:dev:linux # Linux AppImage
JLink Tasks
You can also run JLink steps individually:
task desktop:jlink # Build JAR + create JLink runtime
task desktop:jlink:jar # Build backend JAR only
task desktop:jlink:runtime # Create JLink custom JRE only
task desktop:jlink:clean # Remove JLink artifacts
Clean
task desktop:clean
Removes all desktop build artifacts including JLink runtime, bundled JARs, Cargo build, and dist/build directories.
