pdftk – the PDF toolkit

Pdftk is a simple tool for doing everyday things with PDF documents. If PDF is electronic paper, then pdftk is an electronic stapler-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses.

Pdftk is a front end to the iText library. It’s capable of splitting, merging, encrypting, decrypting, uncompressing, recompressing, and repairing PDFs. It can also be used to manipulate watermarks, metadata, and forms.

It’s a very versatile toolkit.

Features include:

  • Merge PDF documents.
  • Split PDF pages into a new document.
  • Decrypt input as necessary (password required).
  • Encrypt output as desired.
  • Fill PDF Forms with FDF Data and/or Flatten Forms.
  • Apply a Background Watermark.
  • Report PDF on metrics, including metadata and bookmarks.
  • Update PDF Metadata.
  • Attach Files to PDF Pages or the PDF Document.
  • Unpack PDF Attachments.
  • Burst a PDF document into single pages.
  • Uncompress and re-compress page streams.
  • Repair corrupted PDF (where possible).
