The Best 100% Client-Side Tool Suite — Free, Private & Secure
InBrowserTools is a privacy-first file processing suite that runs entirely in your browser. Unlike Smallpdf, ILovePDF or TinyWow, your files are never sent to any server. Every operation — PDF edit, image compression, document conversion, PDF redaction, metadata removal, PII scrubbing and log file analysis — happens on your own CPU using WebAssembly and browser-native APIs. It is a genuine zero-knowledge PDF editor built for GDPR- and HIPAA-sensitive workflows — ideal for individuals, law firms, healthcare providers and security teams.
The new PDF Redaction tool permanently blacks out sensitive text in PDFs with auto-detection of emails, phone numbers, SSNs and credit card numbers. The PII Scrubber detects and removes personally identifiable information from any text before you paste it into ChatGPT, Claude or other AI tools — with dummy data replacement and tokenization modes. The Metadata & EXIF Remover strips GPS coordinates, camera details, author names and creation dates from images, PDFs and DOCX files. The Log File Parser is a full incident response tool that detects SQLi, XSS, Log4Shell, brute force attacks and extracts IOCs — all without uploading sensitive company logs to a third-party service.
For document work, the new Invoice Generator creates professional PDF invoices with currency conversion, custom colour themes and signature upload — entirely in browser. Combined with the existing 30+ tools for PDF, image, data and developer tasks, InBrowserTools is the most comprehensive offline-capable browser-based tool suite available for free.

💻 Developers & Data Teams
JSON formatter, JWT decoder, UUID generator, SHA256, MD5, hex-to-ASCII, Base64, YAML converter, Markdown previewer, Unix timestamp converter, and a secure password generator — all client-side. Scrub PII from payloads before sending to AI assistants.
💼 Business & Finance

Frequently Asked Questions
Are these tools truly private with no upload?
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.
How does the PDF Redaction tool work?
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.
What is the PII Scrubber and why do I need it?
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.
What metadata does the Metadata Remover strip?
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.
What can the Log File Parser detect?
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.
Is InBrowserTools GDPR and HIPAA compliant?
InBrowserTools is architected for GDPR- and HIPAA-sensitive workflows: all processing is 100% client-side, so no file content, filename or metadata is ever transmitted, stored or logged on any server. Because no data leaves your device, there is no data processor relationship to manage. Note that compliance certifications apply to organizations and their practices — the tools give you a no-transmission architecture that makes compliant workflows straightforward.
What is a good free secure alternative to Smallpdf or ILovePDF?
InBrowserTools offers the same core features — merge, split, compress, edit, watermark, protect and convert PDFs — but processes everything in your browser instead of uploading files to a server. It is free, requires no registration, has no file limits beyond your device's memory, and adds privacy tools like PDF redaction, PII scrubbing and metadata removal that server-based suites do not offer.
Does InBrowserTools work offline?
Yes. Once a tool page has loaded, all processing runs locally in your browser, so you can disconnect from the internet and keep working. Your files are processed by your own CPU using WebAssembly and browser-native APIs — no server connection is needed for any file operation.
