New · Redaction

Redaction that takes the data out of the file.

Send a PDF or a scan. Tranly finds the personal data, you check every area, and the data leaves the document — not just the screen. The rest of the page stays exactly as it was.

Start redacting How it works

On the Pro plan and above. 1 credit a page to find the data; applying it after that is free.

A rental contract as it was sent. A sample document: every name and number on it is invented.

What came back: the tenant's name, CPF, date of birth, e-mail, phone, address and bank account are gone from the file. The landlord and the clauses stayed.

Paint over text is not redaction

Three ways a document that looks redacted still gives the data away.

The text is still under the box

A rectangle drawn over a PDF covers the letters on screen. The letters stay in the file, and anyone can select and copy them. We remove them from the file.

The name lives in more than one place

The author field, a form value, a note or a bookmark can repeat the same name. We remove a covered text from all of them.

A scan keeps its pixels

On a scanned page the data is the picture. We erase the pixels under each box, and the box marks where they were.

Three steps, and you approve each one

Nothing is removed until you say so.

Choose what to hide

Upload a PDF or an image and pick the kinds of data to find. Add your own words, such as a project name.

Check the areas

Every proposed area is drawn on the page. Click to keep or drop it, or drag to add one.

Download the verified PDF

We remove the data, read the file again to prove it is gone, and hand you the PDF.

What it finds

Pick any of these, in Portuguese, English, Spanish, French and German documents.

Names of people
ID numbers (CPF, RG, SSN, passport)
E-mail addresses
Phone numbers
Postal addresses
Dates of birth
Bank accounts and cards
My own texts

Numbers with a check digit — CPF, CNPJ, IBAN, payment cards — are checked before they are proposed. You review every area before anything is removed.

For developers

The same redaction, from your code

Detect with one call, apply with another, or do both in one call for a pipeline with no review. Synchronous answers, signed webhooks and idempotency work as they do for translation.

Request

# 1. Find the data. Each area is a page, a box and a category.
curl -X POST "https://api.tranly.co/v1/redact/detect" \
  -H "x-api-key: $TRANLY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "source": { "kind": "pdf", "contentBase64": "JVBERi0xLjcKJ..." },
    "categories": ["person_name", "id_number", "email"]
  }'

# 2. Remove the areas you kept. Naming the detection makes this call free.
curl -X POST "https://api.tranly.co/v1/redact/apply" \
  -H "x-api-key: $TRANLY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "detectionJobId": "9b1e...",
    "areas": [{ "id": "p1_a0", "page": 1, "category": "person_name",

  }'

Part of the Pro plan

Redaction is included from the Pro plan up. Finding the data costs 1 credit a page, like a translated page. Applying it after a detection of the same file is free.
