FDF to PDF PHP Overview

Import FDF (Forms Data Format) into PDF documents that contain corresponding interactive form fields. Field values are mapped by name and written into the appropriate PDF form fields to produce an updated, ready‑to‑use document. Handle password‑protected PDFs when required and validate that the form structure matches the FDF schema before applying changes. Designed for automation, the PHP SDK delivers predictable results for e‑forms processing, records management, and downstream approval workflows.

File

File Supported formats: .pdf

File to be converted. Value can be URL or file content.

FdfFile

File Supported formats: .fdf

Specifies the FDF file that contains structured form data. Value can be URL or file content.

Password

String

Sets the password to open protected documents.

StoreFile

Bool Default: False

When the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.

When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
