File

File Supported formats: .rtf

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

InlineImages

Bool Default: True

Inline images to html.

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.
