convert_file

convert

Convert a file between any of Convert Fleet's 178+ supported formats (documents, images, audio, video, e-books, archives, fonts, spreadsheets). Provide the input as a public file_url (preferred) or inline file_base64 + filename, and the target_format (e.g. 'pdf', 'mp3', 'docx', 'webp'). Returns a short-TTL signed download URL for the converted file. Use list_supported_formats first if unsure a target is valid.

Parameters

Name	Type	Required	Description
file_url	string	no	Public http(s) URL of the input file (preferred for agents). Internal/metadata IPs are blocked.
file_base64	string	no	Base64 of the input file for small inline uploads (<=15MB). Provide 'filename' too. Use file_url for larger files.
filename	string	no	Original filename incl. extension (used to detect the source format), e.g. 'invoice.docx'.
mime_type	string	no	Optional MIME type of the input.
target_format	string	yes	Target format extension, e.g. 'pdf', 'png', 'mp3', 'docx', 'webp'.
source_format	string	no	Optional explicit source format if it can't be inferred from the filename.
output_filename	string	no	Optional desired output filename.
