Fill forms
With the UI or programmatically
Limitations and known issues
- XFA forms: XFA forms aren’t supported; convert them to AcroForms or flatten them to static PDFs.
- Dynamic behavior: PDF form JavaScript, calculations, and custom actions are only partially supported; complex dynamic logic may need to be handled in your app.
- Field type restrictions: Some field types or appearances (for example, rich text, barcode, or custom widgets) can render as plain text or be read-only in the web UI.
For detailed workarounds, see troubleshooting.

What are forms?
The concept of forms in PDFs is similar to that of a form in the physical world. Forms allow a user to enter unique information into a preformatted page. As it’s an electronic format, PDF offers certain advantages to users — for example, the ability to edit entered information at a later date.
