PDF redaction for macOS and Windows
Permanently remove sensitive information from PDFs and scans. Save a checked copy and a report, without uploading your documents.


Original preview
Example data only. No file is uploaded.
No cloud.
Nothing is uploaded, ever. There is no upload path in the app.
No servers.
Your documents never touch a server: not ours, not anyone's.
100% private.
Every page is processed on your Mac or PC, even offline.
The app connects only to check your license key, to send error reports and, if you allow it, to fetch signed rule updates. No document data is ever sent.
01 / The problem
Many tools only paint over the page. The text is still in the file: copy, search or a metadata viewer brings it back. RedactFirst rebuilds every redacted page, so there is nothing underneath to find.
Patient: Jane R. Doe
SSN: 481-55-9027
Copied text: 481-55-9027
Patient: Jane R. Doe
SSN:
Copied text: (nothing)
Example data. Redacted pages become images, so their text can no longer be selected or searched; pages you did not redact keep their text.
02 / How it works
Your original file is never changed. RedactFirst always writes a new, single-revision copy.
Open a PDF, a scan or a whole folder. A rule set suggests what to remove: SSNs, card and account numbers, emails, phone numbers, dates of birth, addresses, names and your own word lists. Scanned pages are read with the text recognition built into your computer.
Every suggestion is a box you approve, ignore or redraw. Label boxes PII, PHI, PRIVILEGED or (b)(6). Find one value and RedactFirst marks it everywhere, in every way it is written.
RedactFirst rebuilds the copy, re-opens it from disk and runs six checks that do not share code with the redaction itself. Only a copy that passes is saved, next to its PDF and JSON report.


03 / Verification
The check is independent of the code that removed the text. If any check fails, the copy is held back, and RedactFirst shows which text remained on which page, masked.
How the engine works →
Every saved copy keeps its pages and little else. These are removed from every output:

04 / Private by design
05 / Built for real caseloads
Checksums keep numbers honest: card numbers pass Luhn, IBANs pass mod 97, routing numbers pass their checksum, before they are ever suggested.

What RedactFirst finds
Drop a folder, apply one rule set, get a folder of checked copies and a summary report.
Automatically redact new files in a chosen folder while the app is open, using your selected rule set. Files are processed without manual review.
Ready-made sets by line of work. Save and share your own as JSON, and try them on sample text first.
A PDF and JSON report per copy: SHA-256 of input and output, rule set, every redaction by page and type, every check.
Per-box labels such as PII, PHI or (b)(6), page stamps and Bates numbering.
Original and redacted preview side by side, with the list of pages that change.
Finder's Open With, the Services menu, Explorer's right-click menu or the command line.
Every copy with its report details, kept locally. Turn it off or clear it any time.
English, Spanish, German, French (Canada), Portuguese (Brazil) and Turkish.
06 / Who it is for

10 / Questions
Yes. Every page with a redaction is rebuilt as a picture with the boxes painted into its pixels, so the text under a box no longer exists in the copy. The copy is then re-opened from disk and checked six ways. A copy that fails is not saved.
No. RedactFirst has no cloud service. Documents, their text and what RedactFirst finds are never sent anywhere. The app only connects to check a license key, to send error reports that contain no files or document contents and, if you allow it, to download signed rule template updates.
Yes. Pages without a text layer are read with the text recognition built into macOS or Windows. Recognized boxes are drawn generously and the app asks you to look closely, because recognition of scans is never perfect.
No software can do that on its own. RedactFirst is a tool that helps you remove information and documents what it did; you decide what to remove and remain responsible for your obligations. Its suggestions can miss things, so review every page.
You can still open, search and review documents. Copies you save carry the word TRIAL across every page and come without a report until you activate a license. Your settings and rule sets are kept.
Yes. One license key works on macOS and Windows, in any mix, on computers you own or control. You buy a number of computers, not an operating system.
A license is a one-time purchase for 1, 3 or 5 computers, depending on the package you choose. Each computer where you enter the key uses one of them. To move to a new computer, choose Remove license from this computer in Settings > License on the old one, then enter the key on the new one. If the old computer is lost or broken, write to support and we will free its activation.
On macOS, names are suggested with the language tools built into the system. On Windows, names are found from the word list you enter, such as client or patient names. Every other detector works the same on both.
PDF, including password-protected PDFs, and scanned images in PNG, JPEG and TIFF. Images are turned into a PDF first and then redacted like any other document.
