Questions
Frequently asked
Is this a subscription?
No. Guardian PDF is a one-time purchase — you pay once and own it forever, including 12 months of free updates. After that, updates are optional via the low-cost Updates+ plan, but the app keeps working either way.
Are my documents uploaded anywhere?
No. Guardian PDF runs entirely on your own PC. Your files are opened, edited and saved locally and are never sent to us or any cloud service.
Which computers does it work on?
Guardian PDF runs on 64-bit Windows 10 and Windows 11. A Mac version may follow later — let us know if you'd like one.
Can I edit text that's already in a PDF?
Yes. Use the Edit-text tool to change existing words, or built-in OCR to turn a scanned, image-only PDF into editable text first.
Can I use it on more than one computer?
A Personal licence covers one PC. Need several? The Business plan offers volume licensing for teams and offices on a single invoice.
What if it's not for me?
Every purchase is covered by a 30-day money-back guarantee. If Guardian PDF isn't right for you, just let us know and we'll refund you.
