Remove all encryption from a PDF, including open passwords and permission restrictions.
The PDF Decrypt API removes password protection and restrictions from PDF files. Provide the file password (owner or user) to unlock the document. The output will be a fully decrypted PDF with no security constraints.
Pass your API key as the apiKey parameter in every request.
This is version v1.0 of the API.
The PDF Decrypt API accepts a file upload, query parameters, and webhook headers described below.
The request body is a single optional file upload sent as multipart/form-data. All other parameters (including file_id and file_password) are passed as query parameters, not in the request body.
