pdftk 命令

常用示例

说明

pdftk (PDF Toolkit) is a command-line tool for manipulating PDF documents. It can merge, split, rotate, encrypt, decrypt, fill forms, and modify metadata without quality loss. Page selection uses flexible syntax: ranges (1-5), specific pages (3,7,10), reverse order (end-1), and rotation suffixes (north, south, east, west). Multiple input files can be combined with per-file page selections. Form handling fills interactive PDF forms from FDF (Forms Data Format) or XFDF data files. The dump_data_fields command extracts field information for preparing fill data. Flatten permanently merges form data into the document. Encryption options set owner and user passwords with permission controls. Owner password grants full access; user password can have restricted permissions (no printing, no copying, etc.). The stamp and background operations overlay PDFs, useful for watermarks, letterheads, or combining content. Attachments can embed files within PDFs.
