Redact PDF processes files locally in your browser.

Permanently redact a PDF in your browser

Draw one or more boxes over sensitive text or images and Redact PDF permanently removes that content — pages you redact are flattened to an image, not covered with a removable overlay. Runs entirely in your browser, no uploads required.

How to redact a PDF

  1. Select or drop a PDF.
  2. Navigate to each page that has sensitive content.
  3. Draw a box over each area to redact.
  4. Select Redact & download.

Browser privacy

  • Redaction happens locally in the browser.
  • Your file is not uploaded to Looty Tools.

Limits

  • Maximum file size is 25 MB, up to 200 pages (50 flattened per file).
  • Pages with a redaction box are permanently flattened to an image — text on those pages is no longer selectable or searchable, and links, form fields, or annotations on those pages are removed.
  • Pages without a redaction box keep their original visible/vector content and are not rasterized.
  • Document metadata, bookmarks, and form fields are not preserved in the output.
  • Password-protected PDFs are unsupported.

Redact PDF FAQ

Is my PDF uploaded when I redact it?
No. Redact PDF runs entirely in your browser using pdf-lib and PDF.js. Your file is never uploaded to Looty Tools.
Is a black box really enough to redact a PDF?
A black rectangle drawn on top of existing PDF text is not real redaction — the original text usually remains selectable, searchable, and recoverable underneath it. Redact PDF instead rebuilds each redacted page as a flattened image, so the covered content is not present in the output at all.
What happens to a page after I redact it?
Pages with a redaction box are permanently flattened to an image. Text on those pages is no longer selectable or searchable, and any links, form fields, or annotations on those pages are removed. Pages without a redaction box keep their original visible/vector page content and are not rasterized.
Does Redact PDF preserve document metadata, bookmarks, or form fields?
Not currently. Redact PDF focuses on permanently removing selected visible page content. Document-level metadata, outlines/bookmarks, and form fields are not carried into the redacted output.
Will the file size change after redacting?
It can. Flattened pages become images, which may be larger or smaller than the original vector content; unredacted pages keep their original size and quality.
What is the maximum file size and page count?
Redact PDF accepts one PDF up to 25 MB and 200 pages, with up to 50 pages flattened (redacted) per file.
