Octavo PDF Tools

Octavo is a Windows app for everyday PDF work that makes no network connections at all. You can merge PDFs; reorder, rotate, delete, split and extract pages; protect a file with an AES-256 password or remove one; make scanned pages searchable with on-device OCR; edit and sign with text, cover-and-retype, whiteout, shapes, pen, images, signatures, highlights and comments; and turn JPEG, PNG, TIFF, BMP and GIF pictures into PDFs. It’s a WPF app on .NET 10, built around bundled command-line engines: qpdf and my own static build of Tesseract. It’s packaged as an MSIX and sold on the Microsoft Store.
