Frequently asked questions
Is it safe to redact PDFs online?
With StylusPDF, yes — and it matters here more than anywhere. Redaction happens entirely inside your browser on your own device, so your sensitive documents are never uploaded, stored, or seen by anyone else.
Does the hidden text really get removed?
The redacted areas are covered so the information underneath isn’t visible in the exported file. For highly sensitive documents, always review the result before sharing.
Is redacting PDFs free?
Yes. You can redact PDFs for free without creating an account. A free account gives you more daily downloads, and StylusPDF Pro removes all limits.
Can I redact multiple areas?
Yes. Draw as many redaction boxes as you need across any pages before exporting.
Do I need to install anything?
No. StylusPDF runs in your web browser. There’s nothing to download or install, and it works on any device.
