PDF redaction guide
How to permanently redact visible details in a PDF on iPhone or iPad
Blurpeg lets you place manual redactions page by page, then creates a new image-only PDF with those visual regions flattened into each page.
Free to download. One free export: a photo or one complete PDF. Optional one-time purchase for unlimited photo and PDF exports.
Redact a PDF in five steps
- Open Documents and choose a PDF. Select the source through Apple's Files picker. Blurpeg processes it locally.
- Review every page. PDF redaction is manual. Blurpeg does not automatically find names, account numbers, signatures, faces or other sensitive details in a PDF.
- Add and resize each region. Place a redaction over the complete visible detail. Use Solid concealment when the content must be fully covered, or Mosaic where that treatment suits your purpose.
- Move between pages and check your work. Redactions remain associated with their pages while you review the document.
- Export a new PDF. Blurpeg rasterises every page and generates a separate, image-only PDF. The original remains unchanged.
Flattened is different from drawing a box
A removable annotation can leave the underlying text or image available. Blurpeg instead rasterises the source pages and draws the selected visual redactions into the newly generated page images. Source searchable text, OCR layers, annotations, form fields, attachments, scripts, hidden layers and earlier revisions are not carried into that output.
Always inspect the exported file.
Open the new PDF, check every page and confirm that each intended detail is concealed before relying on or sharing it.
What changes in the output
Rasterising a PDF can change searchability, accessibility, links, forms, annotations, file size, image quality and digital signatures. The output receives new creation, modification and producer metadata, and its suggested filename retains the source filename with -redacted.pdf added.
Blurpeg provides visual redaction, not a legal determination that a document meets a particular disclosure, court, regulatory or records-management standard.
