What is XFA?
XFA (XML Forms Architecture) is an older Adobe-specific technology used to create dynamic and interactive PDF forms.
Unlike standard PDF forms (AcroForms), XFA stores form structure and data in XML, which allows:
- Complex data entry layouts
- Calculations and validations
- Dynamic form fields and business rules
- Offline form filling
- Advanced branding and layout customization
XFA was introduced with PDF 1.5 as a proprietary Adobe technology and was never standardized as an independent ISO format. XFA is deprecated in the PDF 2.0 standard (ISO 32000-2) and is no longer considered part of modern PDF compliance. Because of this:
- Many modern PDF viewers and editors do not support XFA
- Supporting XFA requires specialized proprietary processing
- The industry standard for forms is AcroForms, not XFA
- For long-term compatibility, archival workflows (e.g., PDF/A), and interoperability, XFA is generally avoided.
Expert PDF does not currently support XFA forms because they rely on a complex, proprietary structure and an outdated technology standard, but our team is looking into improving compatibility in future versions.
Can I convert XFA to a standard PDF and then open and edit it in Expert PDF?
Yes. We recommend converting the form design to AcroForms for modern compatibility using online or third-party conversion tools.
Note that the form's functionality may be reduced depending on its complexity.
Still need help?
If you received an XFA file from a government agency or enterprise system, we recommend requesting a standard PDF or AcroForm version for full compatibility with modern PDF tools.
