Question 1

Are these tools truly private with no upload?

Accepted Answer

Yes — every tool is a genuine no-upload file processor. Your files are loaded into browser memory using FileReader, processed by JavaScript libraries (pdf-lib, PDF.js, mammoth.js, JSZip), and the result downloads directly. No file content, filename or metadata is ever transmitted. This includes the PDF Redaction, PII Scrubber, Metadata Remover and Log Parser tools — none of them send any data to a server.

Question 2

How does the PDF Redaction tool work?

Accepted Answer

The PDF Redaction tool uses PDF.js to render your document on an HTML5 canvas and pdf-lib to burn permanent black rectangles over selected content. You can draw manually, use freehand brush, or enable Auto-Detect to find emails, phone numbers, SSNs, credit cards, IP addresses, dates and URLs. Preview mode shows amber highlights before committing. Three redaction styles: black bar, red CLASSIFIED stamp and hash block. The redacted text cannot be recovered by selecting, copying or inspecting the downloaded PDF.

Question 3

What is the PII Scrubber and why do I need it?

Accepted Answer

The PII Scrubber detects and removes personally identifiable information from text before you paste it into public AI tools like ChatGPT or Claude. It detects emails, phone numbers, SSNs, credit card numbers, dates, IP addresses, URLs, full names, addresses and ZIP codes. Four modes: remove entirely, redact with black blocks, replace with dummy data, or tokenize with labels like [EMAIL_1]. All detection runs locally — your text never leaves your browser.

Question 4

What metadata does the Metadata Remover strip?

Accepted Answer

For images (JPG, PNG, WEBP): GPS coordinates, camera make and model, lens info, ISO, aperture, shutter speed, date taken, artist, copyright and embedded thumbnails. For PDFs: Title, Author, Subject, Creator, Producer, Keywords, CreationDate, ModDate and XMP metadata stream. For DOCX, XLSX and PPTX: author, last modified by, company, manager, revision number and creation dates. For MP4 and MOV videos: encoder name, GPS coordinates and Apple ID fields zeroed in-place.

Question 5

What can the Log File Parser detect?

Accepted Answer

The Log File Parser scans raw system logs locally to identify security threats, anomaly profiles, persistent scraping clusters, unauthorized administrative entry attempts, and network errors without passing diagnostic trace files over the web.
