Open a PDF, click the text you want to change, and change it. Reorder, rotate, extract, split and merge pages. Add headers, footers, watermarks, page numbers and Bates numbering across a whole document.
Common questions
Does CompendiumPDF upload my documents?
No. Opening, editing, OCR, conversion, compression and redaction all run on your own computer. The only time a document is transmitted is if you explicitly send it for signature through Compendium Sign.
What does it cost?
One license is $25 a month and covers five named users, which works out at about $5 per person. Prepaying a year takes 5% off, and five years takes 40% off. An optional AI assistant is $5 per user per month.
Does it work offline?
Yes. The Windows application is fully offline. It checks its license every 45 days, and if it cannot reach the internet it keeps working normally within that window.
What happens if I stop paying?
The application drops to read-only. You can still open, read, search, annotate and print every document you have. You are never locked out of your own files.
Can I use it in a browser?
Yes. There is a browser version that runs the same engine, so the PDF is still processed on your device rather than on a server.
