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 and a GDPR-compliant, HIPAA-safe tool suite 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.
Password-protect contracts, watermark NDAs, redact sensitive names and account numbers from PDFs, and remove document metadata before sharing. A true HIPAA-safe PDF converter and no-server file editor — confidential client documents never leave your machine.
Use the Log File Parser for incident response — detect SQL injection, XSS, Log4Shell and brute force attacks with MITRE ATT&CK mapping. Extract IOCs. Use the PII Scrubber to safely use AI tools with sensitive data. Export findings as CEF for SIEM ingestion.
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.
