PaperFlow

PaperFlow is a complete PDF toolkit that works entirely on your computer.
Nothing is uploaded, no account is needed, and it works without an
internet connection.

- Merge, split, organize, rotate and extract pages, with real page
thumbnails, drag-and-drop reordering and undo.
- Compress PDFs with quality presets and see how much space you saved.
- Convert pages to PNG or JPEG, images to PDF, and PDFs to text, or
extract the pictures embedded in a document.
- Add text or image watermarks and page numbers with a live preview.
- Edit document metadata.
- Protect PDFs with AES-256 passwords and permissions, or remove a
password you know.
- Make scanned documents searchable with OCR in 17 languages.
- Read, search and navigate PDFs in the built-in viewer.

Ghostscript, Poppler, qpdf and Tesseract with its language data are
included, so every tool works out of the box.
