What is CompendiumPDF?

Questions, answered
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 can’t 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’re never locked out of your own files.
Can I use it in a browser?
Yes. There’s a browser version that runs the same engine, so the PDF is still processed on your device rather than on a server.
Is CompendiumPDF a drop-in replacement for Acrobat Pro?
Not for every workflow. It covers about 43% of Acrobat Pro’s published feature list, concentrated in editing, page operations, forms, OCR, redaction, conversion and signature. It doesn’t yet do accessibility tagging, prepress and preflight, batch automation or Office-format import.
How is redaction different from drawing a black box?
A black box leaves the original text in the file, where it can still be extracted. CompendiumPDF converts the affected pages to images so the underlying text is destroyed rather than hidden.
Which languages does the OCR support?
English, Spanish, French and German.
What does the installer include?
One installer covers CompendiumPDF, CompendiumWP and Compendium LECX, and it installs without administrator rights.
How much is the AI assistant?
The AI assistant (document summaries, questions about a document, drafting help and image generation) is $5 per user per month and optional. You only pay for the people who turn it on.
