PDF generation settings support accessibility features such as accessibility tags for screen readers, customizable export formats, and image retrieval timeouts for optimized HTML to PDF conversion.  
Note:  
PDF generation with accessibility is unavailable for on-premise customers.

## Accessible PDF {#pdf-generation-accessibility__section_clt_gcy_mdc}

To enable accessibility for PDF generation, add the accessibility property com.snc.pdf.generation.accessibility and set the value to <kbd class="ph userinput">true</kbd>. Only users with admin roles can set the
property. For more information, see [Add a system property](https://www.servicenow.com/docs/access?context=t_AddAPropertyUsingSysPropsList&version=zurich&pubname=zurich-platform-administration&ft:locale=en-US).

For PDF generation API, see [PDFGenerationAPI - Scoped, Global](https://www.servicenow.com/docs/access?context=PDFGenerationAPIBothAPI&version=zurich&pubname=zurich-api-reference&ft:locale=en-US)

## Image retrieval timeout in HTML to PDF conversation {#pdf-generation-accessibility__section_ewq_bb3_tfc}

To specific the time out duration for HTML to PDF conversion update the timeout value for the system property com.snc.pdf.html2pdf.image_retrieval_timeout. This property enables you to specify an image
retrieval timeout in seconds.
* **[Export to PDF](https://www.servicenow.com/docs/xQwOX2OuPeO_SE8au2sWYA)**   
  Export an individual record or list of records into a PDF format that supports accessibility. When this feature is enabled, accessibility tags are available in the PDF tag tree to help users who rely on-screen readers to navigate, understand, and interact with the generated PDF documents.
* **[Guardrails for PDF generation and accessibility](https://www.servicenow.com/docs/G1axGfs7rK2r8p70Agb4Fg)**   
  Static and dynamic guardrails are safeguards that help maintain stability during PDF generation. Static guardrails enforce fixed limits like maximum PDF size, while dynamic guardrails monitor real-time memory usage and terminate exports when memory pressure exceeds a defined threshold.
