PDF Redactly vs SafeRedact
SafeRedact is a genuinely privacy-conscious redaction tool, and a fair comparison — your file stays in your browser and it does true, permanent redaction. Its detection is powered by a capable cloud AI, which makes it good at catching nuanced, context-dependent PII.
But there's a distinction worth understanding. SafeRedact keeps the file local yet, by its own description, sends the extracted text to an external AI API for detection — so the words on your document (which are the sensitive part) do travel to a server. PDF Redactly runs detection with an on-device model: no file and no text leaves your browser, for any feature. Here's an honest comparison of the trade-off.
Why people switch
SafeRedact keeps the file local, which is good, but sends the extracted text to a cloud AI to find PII. The text is the sensitive part. PDF Redactly detects on-device, so nothing — not the file, not the text — is transmitted. Open your network tab and you'll see no requests at all.
SafeRedact's free output carries a watermark until you pay. PDF Redactly's free tier produces clean, unwatermarked redacted PDFs with no document limit.
Because there is no external call for any feature, you can verify PDF Redactly's guarantee yourself: disconnect your network after the page loads, and redaction still works.
Where SafeRedact wins: its cloud AI can be better at nuanced, context-dependent PII than an on-device model, and it handles image files (JPG/PNG) as well as PDFs. If you're comfortable with extracted text being sent to a well-secured AI API in exchange for that accuracy, it's a solid, privacy-minded tool. If your standard is that nothing at all leaves the device, that's what PDF Redactly is built for.
FAQ
No — SafeRedact keeps the file in your browser. But by its own description it sends the extracted text to a cloud AI for detection, so the text content does leave the device. PDF Redactly detects on-device, so nothing is sent.
SafeRedact's cloud AI may catch more nuanced, context-dependent PII. PDF Redactly trades some of that for a hard guarantee that no text ever leaves your device, and pairs its on-device model with 30+ regex categories.
No. The free tier produces clean redacted PDFs with no watermark and no document limit.
