Redact sensitive text in a PDF (video walkthrough)
What this video is showing (in plain English)
The video demonstrates how to black out (redact) specific text inside a PDF in DocKosha, and then save a new redacted copy so the original file stays unchanged.
Step-by-step (follow this exactly)
Step 1 — Open the PDF you want to redact
- Go to Data Rooms (left sidebar).
- Open the folder/data room where your file lives (in the video it’s Investors Docs).
- Click the PDF to open the document viewer.
Step 2 — Start redaction mode
- On the right side, in Document details, click Redact Document.
- This takes you to a dedicated screen called Document Redaction.
Think of this as “edit mode” for redactions. Nothing is final yet.
Step 3 — Select the text you want to hide
- Scroll (or zoom) until you see the text you want to remove.
- Click and drag to highlight the word(s) or phrase(s).
Step 4 — Turn the selection into a redaction
- After you highlight text, a small floating action appears near the selection.
- Click Redact.
- You’ll now see:
- The selected text highlighted in the PDF (marked for redaction)
- A new entry added to the Redactions list on the right (example: “#1 · Page 1 · ‘questionnaires’”)
Step 5 — Repeat for every sensitive part
- Highlight another word/phrase (example from the video: “Secure Sharing” in the title).
- Click Redact again.
- The right-side list grows with each redaction you add.
Step 6 — Review or undo before finalizing
In the Redactions panel (right side):
- Click Remove next to any item to undo just that redaction.
- Click Clear All if you want to remove all redactions and start over.
Step 7 — Apply the redactions (this is the “finalize” step)
- Go to the Apply Redaction section on the right.
- Click the Apply redaction button (it has a dropdown arrow).
- Choose one option:
- Replace current document (overwrites the existing PDF)
- Save as new document (keeps the original unchanged — this is what the video chooses)
Step 8 — Name the new redacted PDF
- If you pick Save as new document, a popup appears: Name redacted document.
- Enter a filename (the video uses something like:
... redacted.pdf) - Click Done and wait while it saves.
Step 9 — Confirm the result
- You’ll see a success message like “Redacted copy created successfully.”
- The newly created PDF opens.
- Verify the sensitive text is now replaced with solid black blocks (true redaction).
Key idea to remember
Marking text ≠ redacting it.
- Highlight + Redact = adds it to the list (a “to-be-redacted” marker)
- Apply redaction = permanently generates the redacted PDF (final output)
Quick safety checks before sharing
- Open the new redacted file and confirm every intended area is blacked out.
- Make sure you share the redacted copy, not the original.
- If you’re unsure, keep your original file untouched and always use Save as new document.
