Why use this tool: Redact a PDF without uploading
Permanently remove confidential information directly in your browser and create a flattened PDF that does not retain the underlying content.
Private browser processing
The tool uses the PDF editor and keeps the document on your device. You do not have to wait for an upload or trust a cloud service with the file contents.
Review before download
Review the result before downloading and continue using text, signature, image and page organization tools. Changes are written only when you choose to export a new PDF.
Original and compatibility
Keep a copy of the original when working with important documents. Complex PDFs can contain embedded fonts, layers or restrictions that depend on the software used to create them.
Long and complex documents
Multi-page documents use progressive thumbnails and an automatic mode for large files. Pages do not have to be rendered all at once, which reduces memory use and interface delays. Actual performance depends on the device, file size and graphical complexity of the PDF.
Check before sharing
Before exporting, review the pages and every element you added. The downloaded file is a new copy, which preserves the original and lets you compare the result. For legal or administrative documents, always confirm the required signature type, document requirements and PDF compatibility expected by the recipient.

How to permanently redact information from a PDF
Secure redaction must remove information from the result rather than merely cover it on screen. JunoPDF exports a new flattened copy of redacted pages.
Find every sensitive item
Review names, addresses, identification numbers, signatures, images and repeated occurrences. For scanned documents, OCR can help with discovery, but every page still needs visual review.
Use the Redact tool
Mark the complete area containing confidential information. Do not substitute highlights, ordinary shapes or cropping for redaction.
Export and verify in a second reader
Open the new copy, search for removed text and try to select or copy it. Check properties, attachments, annotations and links separately before sharing.
What redaction produces
Affected pages are rendered into a new flattened PDF. Redacted visible content is not retained as selectable text underneath the covered area.
What is not secure redaction
Black rectangles, highlights, cropping and overlaid text may leave the original information accessible. Visual redaction also does not automatically remove every metadata field or attachment.
Browser processing
The document and redaction areas are processed on your device. The PDF does not need to be sent to a JunoPDF server.
Checks before sharing
Search for removed words and numbers, attempt copy and paste, open the file in a second reader and inspect every page. Keep the original separately so it is not shared by mistake.
Frequently asked questions about PDF redaction
Essential checks before removing confidential information.
Does a black rectangle really remove the text?
Not necessarily. A rectangle, highlight or crop may only hide content visually. Use the dedicated redaction export, which creates a new flattened copy.
How do I verify that redaction is permanent?
Open the exported copy in a second PDF reader. Search for the removed text, try to select and copy it, and inspect every page before sharing the file.
Does redaction automatically remove all metadata?
Do not treat redaction as complete document sanitization. Check properties, attachments, annotations, links and other non-visible information separately.
Is the PDF uploaded to a server?
No. Pages are processed and flattened in your browser. The public verification page explains how to inspect network requests.
