All you need is full API enabled in WebViewer to validare pdf/a js. it supports all versions of PDF/A {% hint style="info" %} **Requirements** *These packages are required to use these features in production. Trial keys have unlimited access to all features* Web SDKPackage: ArchiveFull APILive demo {% endhint %} Sample JavaScript code for using Apryse SDK to programmatically convert generic PDF documents into ISO-compliant, VeraPDF-valid PDF/A files, or to validate PDF/A compliance. Supports all three PDF/A parts (PDF/A-1, PDF/A-2, PDF/A-3), and covers all conformance levels (A, B, U). This sample is utilizing the option to [run code programmatically, without the Viewer.](/web/get-started/without-viewer.md) For other WebViewer implementation options, check out: * [Validate PDF/A - Showcase Demo](https://docs.apryse.com/web/samples/showcase-demo-validate-pdfa) * [PDF/A Conversion - Showcase Demo](https://docs.apryse.com/web/samples/showcase-demo-pdfa-conversion) Or check out the [c](/cli/pdf-a-manager/pdfa-manager.md)[ommand-line tool for batch conversion and validation.](/cli/pdf-a-manager/pdfa-manager.md) ### **Implementation steps** To convert or validate PDF/A programmatically with Web SDK: Step 1: Follow [get started in your preferred web stack for WebViewer](/web/get-started/readme.md) Step 2: Follow set up to [implement Full API code without viewer](/web/full-api/running-without-viewer.md) Step 3: Add the sample code provided in this guide This full sample is included in the [manual download of WebViewer.](/web/get-started/manually.md#1-download-webviewer)

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apryse.com/web/get-started/samples/pdfatest.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
