On-device PDF redaction for Mac, iPhone, and iPad

Redact the PDF. Check the copy.

Excise PDF proposes common private-data patterns, turns selected words into a document-wide search on Mac and iPad, and lets you review matches before it writes. Then it reopens the separate copy and reports what it checked and what still needs your review.

Automatically searches six common formats. Clears fourteen supported hidden-data categories. One deliberate review before anything is written.

How it works

Find it. Review it. Check the copy.

Three steps take you from the original PDF to a checked copy you can compare before saving. These are current build-11 captures, not mock-ups.

  • Step 1 in Excise PDF on Mac: the app proposes common private-data patterns, while selected text on the page is offered as either one occurrence or every matching occurrence across the PDF.
    01 Find and mark what needs to go.

    Excise starts by proposing common private-data patterns. You decide which to add, then add any names, numbers, or phrases of your own.

    • Automatically searches for six formats: Social Security numbers, card numbers, IBANs, email addresses, phone numbers, and dates. Date search is off by default.
    • On Mac or iPad, select text on the page and mark this occurrence or every matching occurrence across the PDF.
    • Add as many searches as the job needs in the left panel. Each rule shows how many page-text matches it found.
    • Draw a rectangle around a signature, stamp, image, or mixed area that text search cannot name.
    • Nothing is applied automatically. Proposals and matches move to Review.
  • Step 2 in Excise PDF on Mac: the Review list shows a selected text match and a marked area in context, with a notice that the affected page will be converted to an image before the user presses Redact.
    02 Review every match before redacting.

    Excise shows every match in context and every area you marked. On Mac and iPad, uncheck any occurrence you want to leave in the copy.

    • See the surrounding words, page number, replacement, and any exemption code for each match.
    • Marked areas show what they cover and whether the page will be converted to an image.
    • On Mac and iPad, review one occurrence at a time; an unchecked match is deliberately left in place and keeps the result from passing.
    • Press Redact only after the list is right. Excise writes a separate staged copy; your original stays unchanged.
  • Step 3 in Excise PDF on Mac: the reopened redacted copy appears beside a Verified result, a hidden-data summary, Original and Redacted copy controls, and the Save the copy button.
    03 Check the copy, then save it.

    Excise reopens the staged redacted copy and bases its result on what it reads back, not on what the run intended to do.

    • Switch between Original and Redacted copy before you save.
    • It re-extracts every page's text and checks the document structure for strings your rules still target.
    • Fourteen supported hidden-data categories are cleared by default, including metadata, form fields, bookmarks, annotations, and embedded files.
    • Excise keeps unaffected text live when it can do so safely. When it cannot, Excise can convert the page to an image to complete the redaction; the receipt tells you when it does.
    • The result is explicit: Verified, Review required, or Not verified.

Hidden data

Fourteen supported hidden-data categories, cleared by default.

Taking a name off the page is half the job. A PDF keeps copies where no reader ever looks. All fourteen are cleared by default, and the receipt names anything you chose to keep.

One purchase, three platforms. Each says what it reviewed.

The same engine everywhere. What differs is how much of the review a screen has room for, and the app says which is which.

Mac

  • Rules, page, review list and receipt in one window.
  • Select text and choose “Mark this occurrence” or “Mark every occurrence.”
  • Batch mode: point it at a folder, one combined receipt, refusals and failures included.
  • The headline counts verified, not written: 39 of 40 verified; 1 document needs attention.
Rules were reviewed once for the folder. Individual matches were not reviewed one by one. Every match the rules found was applied.What every batch receipt explains

iPad

  • The full review, not a reduced one.
  • Select text and choose “Mark this occurrence” or “Mark every occurrence.”
  • Per-match checkboxes and the receipt in the inspector.
  • Rectangles drawn with a finger.

iPhone and the share extension

  • Share a PDF from Mail, Files, or Safari.
  • Every match listed before anything is written, and the button says how many it will remove.
On a phone, every match is still listed before anything is written. There is simply no place to uncheck one.Phone review behavior
The share extension on iPhone: every match listed with the words around it, the page it is on and the replacement it will get, above a button naming how many matches will be removed and a note that a copy is written, reopened and checked while the original is not changed.

Who makes this

Built and supported by Kalman Software.

Excise PDF is developed and supported by Kalman Software LLC, a Colorado software company. It is deliberately focused on one consequential workflow: mark what should be removed, review it, check the separate copy, and make the result explain itself.

Support is available directly through Kalman Software. The app also includes searchable, offline Help on Mac, iPhone, and iPad, and this site explains the workflow, saved-copy checks, and supported features.

Find faster. Review deliberately. Check the copy.
