Redaction for confidential documents.
Select a name, a logo or an image once – every copy gets deleted, at any size or colour, even inside a scanned document. CIMs, board decks, contracts, diligence packs, discovery productions, FOIA releases, and de-identified medical records – in under a minute.

Key features
-
Nothing is uploaded
No server, no account, no analytics. The document is opened, read and rewritten inside this tab. No LLM is used. Close it and nothing remains.
-
Text, logos and pictures
Type any word and every occurrence is redacted, even if the word is an image and not in text format. Pick out a logo, signature, or image and every other copy is redacted, regardless of size or colour.
-
Placeholders, not blanks
Optionally label each redaction
[P1],[E2], so a later reader – or a model – can still follow the sentence. The same thing always gets the same label. -
A full set of PDF tools
Merge files, pull pages out, turn them, add text, draw on the page. Save a draft and pick the work up later. Works on a phone as well as a desktop.
Top use cases
-
Before it goes to an AI. Take the names and logos out, then paste the file into any model. The numbers and the argument survive; the party does not.
-
Deal materials. CIMs, board decks, diligence packs. Cover the target once and every copy goes, down to the badge in a chart on page 63.
-
Legal agreements. Counterparties, prices and signatures out. The clauses stay readable, so the precedent can be shared without the deal.
-
Discovery and FOIA. Covered text is gone from the file, not hidden under a rectangle somebody can select through. Each bar says what it removed.
-
Medical records. Names, dates, record numbers and hospital marks off a chart before it is used for research, teaching or a second opinion.
A real deck, redacted
This is Kimberly Clark's investor presentation on their acquisition of Kenvue. Blinded is able to redact the two companies’ logos and names, specific key brands, people's names across the deck, in small print and inside the artwork, while the figures, the charts and the rival brands are left readable. Each redaction is labelled, so the sentence around it still reads coherently, with the private key file only accessible by you.
How Blinded compares
Blinded is the only redaction tool that never takes the file to the cloud, never uses a model, and still automatically finds repeated text, logos and images by sight and removes them completely.
| What is being compared | Blinded | Acrobat Pro | Redactable | KeptPDF |
|---|---|---|---|---|
| Where the file goes | Stays in this tab. Works offline. | Desktop, yes. The web version uploads. | Their cloud. | On device, then a login. |
| What a bar removes | Everything. The page is rebuilt from pixels. | Nothing, until you Apply and Sanitize. | Everything, on their servers. | Everything. Flattened. |
| Logos, stamps, faces | Pick one; every copy goes, any size or colour. | Draw a box. Every time. | Found for you – in the cloud. | Text only. A face still needs you. |
| Names, and words in a picture | Type it once. Caught in the text and the artwork. | Find, one spelling at a time. | Matched in the cloud. | On device, 45 kinds. No visual picker. |
| Proof of privacy | Read the source. The browser enforces it. | None. Trust the operator. | A certificate, from the host. | A checksum on the export. |
| Readable afterwards | [P1] labels; the key stays with you. | Black boxes. | Tokens, mapped in their project. | Tokens, inside their suite. |
| Cost | Free, no account. | A paid seat. | Free for a few, then monthly. | Free with their branding. |

Q&A
Carry on from your draft
A draft holds your marks, not the document – which is why it is a few kilobytes. Keep it as carefully as the document itself: the words you asked to cover are in it, and so is any note you wrote on a page.
The image you picked
Run a second check?
Are you sure?

Image redaction selection
Drag a corner to fit the box to it. A box drawn tightly around the mark finds it far more reliably than a loose one.
