Why REX Paperworks

No subscription

Online PDF editors charge every month and the big-name desktop editor is now subscription only. REX Paperworks is US$79, paid once, with 12 months of updates, and it keeps working after that.

Your documents stay private

Free web PDF tools work by uploading your file to someone else's server. Paperworks does everything on your computer, offline, so a signed contract or a client's drawing is never sent anywhere.

Built for real paperwork

Developed by an engineering consultancy for its own drawings, specifications, contracts and supplier invoices: combine, reorder, stamp, sign, redact and compare revisions.

What's included

Full markup toolkit

Pencil, lines, arrows, shapes, highlighter, text, tick and cross marks, sticky notes, pictures, signature images, and permanent redaction. Select, move, resize, copy and undo.

Pages: move, delete, rotate, extract

Drag thumbnails to reorder (one page or a ticked block), delete or rotate ticked pages, extract pages to a new file.

Combine PDFs

Merge picks several PDFs in one go, appends them in order and opens the combined file in its own tab, ready to reorder and save under a new name.

Make searchable (OCR)

Turn scanned pages into searchable, selectable text without changing how they look.

Convert

PDF to Word, Excel, plain text or images, with table detection for spreadsheets.

Compare

Text and visual differences between two PDFs: see exactly what changed between revisions of a drawing or contract.

Bates numbering, headers and footers

Sequential numbering and custom stamps across a document set.

Forms, password, compress

Fill and lock interactive form fields, password-protect a file, and shrink a PDF for email.

Several documents at once

Open multiple PDFs in tabs, find text with matches highlighted on the page, edit existing text on digital PDFs.

Open and save anywhere

Open a PDF from any folder on your computer or a network drive, and Save to overwrite it or Save As under a new name. Nothing is copied to a server.

Windows and Mac

The same program runs on Windows 10/11 and on Apple-silicon Macs, with the same files and the same markup tools.

Nothing extra to install

Page rendering and OCR engines are built in on Windows; no separate downloads, no internet connection needed.

By buying you agree to the Licence Agreement and Terms of Sale. Third-party components are listed in each product's NOTICES file (Manuals page).

Your licence key is emailed to you at once when you pay. Install the program, enter your name exactly as it appears in the email (and your company if you want it shown), paste the key, tick the licence agreement and click Activate. The key is made for the person named on it and never expires; the program then shows "Licensed to" your name at the bottom of its window and on its About page. It is a one-user licence: each person who uses the program needs their own. There is no free trial for this product: read the manual first, and the 14-day refund policy in the Licence agreement covers a product that does not do what this page says. Runs on Windows 10/11 (64-bit) and macOS 11+ (Apple silicon); see Downloads. On the Mac, OCR uses the free Tesseract engine if you install it. Licence agreement · Website terms · Refunds · FAQ.
