# Convert File to PDF

`POST /sign/conversions`

> **Deprecated.**

*This endpoint was deprecated* on March 24, 2026, and will be sunset on July 1, 2026. Please migrate your existing functionality to the current endpoint:
https://developers.gonitro.com/docs/api-reference/sign/create-document-by-envelope-id , which already supports multiple file types.

The **Convert File to PDF** endpoint transforms various file formats into PDF documents for use with the Nitro Sign API.

  ### Input files
  Supported input document types and formats:

  | Document Type | Formats |
  |---------------|---------|
  | Doc | .doc, .docx, .dot, .xml, .docm, .dotx, .dotm, .rtf |

  | HTML | .html |
  | Powerpoint | .pptx, .ppt |

  ### Output files
  The **Convert File** Sign API endpoint only supports PDF files as output.

  ### Asynchronous Processing
