File tools that never see your files.

Resize passport photos, compress images, format JSON and more. Everything runs on your device, so your files are never uploaded to a server.

Quick Presets · One-Click WorkflowsClick any preset—or drop a file directly onto it—to process your file immediately. You can save your own presets inside any tool.
All tools

Pick a tool. Add a file. Download.

Every tool works the same way, so once you have used one you know them all.

How it works

Three steps, and none of them upload anything.

STEP 1

Add a file

Drop it on the page, choose it from your computer, or paste text. It opens inside this browser tab.

STEP 2

Adjust the settings

See a live preview as you change size, quality or format. Basic settings first, Advanced when you want control.

STEP 3

Download the result

Check the before and after, then save the file. Delete it from the tab with one click when you are done.

Why your files stay private

Each tool runs inside your browser tab, using your own computer. Our servers only send you the page. They never receive your file, because there is nowhere in the page to send it. While a tool works you will see a paper envelope close over your file. That is our way of showing that it stays sealed in your tab.

Do not take our word for it.

Process something above, then look at these numbers. They are measured in this tab.

0

Network requests while processing

Counted from the browser's own request log around every run. It should stay at zero.

Hashing…

Fingerprint of this page's code

A live SHA-256 digest of the runtime code executing in this tab, verified alongside our WebAssembly module hashes.

connect-src 'self'

Blocked by the site's own rules

Enforced by a strict Content-Security-Policy header that blocks the page from contacting any external server.

Try it: open your browser's developer tools, switch to the Network tab, then process a file. You will see no upload. You can also switch off your internet connection first. The tool still works.
For developers and AI agents

The same tools, callable by code.

Every tool is described by one manifest. The page builds its settings from it, and AI agents (Claude, ChatGPT, Cursor) call the same tool through the Model Context Protocol. The same input always gives the same output, whether a person clicked or an agent called.

How Destructive PDF redactor & blackout tool Works Locally in Your Browser

Direct Answer Summary (Optimized for Search & AI Citations)
PrivacyFold's Destructive PDF Redactor permanently burns blackouts into document content streams and scrubs underlying text, vector objects, and metadata in local RAM, eliminating data leaks with zero server transmission.
Technical Privacy Guarantee:Your file is processed 100% locally in your browser memory and is never uploaded. This page contains advertisements served by Google AdSense to sustain free operation without accounts or subscriptions.
Share Privately:(0 trackers · plain links)
Redacting sensitive information from legal filings, government FOIA requests, and corporate contracts requires true destructive removal of underlying data. A notorious failure mode in digital redaction involves placing black rectangles over sensitive text without deleting the underlying text stream—allowing anyone to select, copy, or search the hidden Social Security Numbers, names, or financial figures underneath. PrivacyFold's Destructive PDF Redactor permanently removes both the visual elements and the underlying content stream objects, vector paths, and metadata from the document structure. Running 100% locally in your browser, it ensures that classified and private information is mathematically eradicated before the document ever leaves your workstation.
Step-by-Step Instructions
  1. Open your PDF document in the secure client-side viewer.
  2. Use the redaction cursor to draw blackout boxes over sensitive names, account numbers, or text paragraphs.
  3. Optionally enable automated PII pattern matching to flag SSNs, credit card numbers, and email addresses.
  4. Preview the redactions and select "Apply Destructive Redaction".
  5. Download the permanently sanitized document with verified zero underlying text leakage.
Settings Explained & Safe Configurations
Redaction Mark Style
Choose between solid black fill (standard legal blackout) or cross-hatch outline with exemption codes (FOIA style).
Safe Default: Solid Black (#000000) · Example: Use solid black for court filings and legal NDAs.
Metadata Purge
Automatically strips author names, software creation timestamps, and revision histories that could reveal who drafted the document.
Safe Default: Enabled · Example: Prevents metadata from revealing internal corporate author identities.
Exemption Label (Optional)
Prints statutory FOIA or privacy exemption codes (e.g. "(b)(6) Personal Privacy") over the blackout area.
Safe Default: None · Example: Helpful for government transparency and public records responses.
What to Expect & Performance Benchmarks
A sanitized PDF document where redacted regions cannot be selected, searched, or extracted by any PDF inspection tool.
Execution Latency: Applies and burns redactions at ~35ms per page in WebAssembly RAM.
Supported Limits: Supports PDF documents up to 100 pages per session.
Privacy Verification & Technical Guarantee
Rewrites the PDF page content stream by removing glyph drawing operators (Tj / TJ) within the target bounding boxes and burning a filled path operator.
  1. Redact a sample sentence with the tool and download the output.
  2. Open the output in Acrobat, Chrome, or Preview.
  3. Attempt to highlight or copy text over the black box: confirm no text is selectable or searchable.
  4. Inspect DevTools Network tab to confirm 0 network requests occurred.
Complies with US Judicial Conference Policy on Privacy and Public Access to Electronic Case Files.

Frequently Asked Questions
Can someone copy and paste the text underneath the black boxes in the output PDF?
No. Unlike superficial annotation tools that merely place a black rectangle annotation on top, PrivacyFold destructively removes the text glyphs, font references, and string literals from the PDF content stream. The text no longer exists in the file.
Does this tool satisfy legal standards for court filings and FOIA compliance?
Yes. It adheres to federal court redaction rules (such as US Federal Rule of Civil Procedure 5.2) and FOIA guidelines by completely purging designated characters from both the display layer and search indexing layer.
Are OCR text layers and hidden text stripped as well?
Yes. Any invisible OCR text layer within the specified redaction coordinates is excised from the document object hierarchy.
Is my document uploaded to any cloud server during redaction?
No. The entire rendering, redaction, and file re-generation pipeline executes inside your browser tab via WebAssembly and Canvas APIs. Zero bytes are uploaded.
Does redaction alter the rest of the document formatting or quality?
No. Non-redacted text, vector graphics, and layout structures remain completely crisp and uncompressed.
Can I redact multiple pages in a single document?
Yes. You can navigate through multi-page contracts, apply redaction marks across any number of pages, and burn them all in a single pass.
