## About

## What it does
PDF Redaction lets you permanently remove sensitive content from a PDF by sending the file and a set of redaction boxes. You define the target areas by page number and box coordinates, and the API returns a redacted PDF as a binary file.

Use it when you need to publish or share documents without exposing personal data, account numbers, internal notes, or other confidential text and images. The request accepts one PDF file up to 20 MB and a `boxes` string containing a JSON object that maps page numbers to lists of rectangles. Each rectangle uses `x`, `y`, `width`, and `height` values so you can target exact regions on the page.

The response is the modified PDF file, ready to store, download, or pass to the next step in your workflow. Typical uses include legal document cleanup, compliance workflows, support ticket attachments, and document sharing pipelines where specific areas must be removed before release.

Because the redaction is applied in the output PDF itself, you can build automated systems that remove sensitive areas before a document leaves your app.
