PortableDocs

PortableDocs positions itself as a complete replacement for the scatter of single-purpose PDF websites people usually juggle. From one interface you can convert a PDF into an editable Word document, merge several files, split a document into per-page files archived in a ZIP, compress heavy scans, rotate or reorder pages, stamp page numbers and diagonal watermarks, encrypt with a password, permanently blackout confidential text, remove unwanted pages and attempt to repair files that will not open.

The suite comes in two shapes. The web app is aimed at quick one-off jobs in the browser, while the PortableDocs Desktop app is designed around a drag-and-drop workflow: hold Shift while dragging a file to surface format-conversion options, hold Command on macOS or Control on Windows for the PDF tools wheel (merge, split, compress, repair, numbering, watermarking, encryption, redaction), and hold Control/Alt for file actions such as copying paths, sharing via AirDrop or sending a file to Terminal.

AI is where the product goes beyond a traditional toolbox. A chat panel lets you have a conversation with a PDF — asking questions about clauses, pulling out summaries and surfacing insights without reading the whole document. According to the site, files are processed in memory rather than stored, and encryption uses 256-bit security. Support is handled directly by email.
