File tools that never see your files
InBrowserTools is a suite of 34+ free utilities for PDFs, images, documents and data that run entirely inside your browser. Nothing you open here is ever uploaded, logged or stored — your files stay on your device, always.
Explore the ToolsWhy InBrowserTools exists
Every popular "free online PDF tool" works the same way: you upload your contract, your medical record, your ID scan to a stranger's server, and trust that it gets deleted. We built the alternative — the same convenience, with the upload step removed entirely. InBrowserTools is built and maintained by Ananta Software.
No Uploads, Ever
Files are read into browser memory with FileReader and processed by JavaScript and WebAssembly libraries like pdf-lib and PDF.js. No file content, filename or metadata is ever transmitted — you can even disconnect from the internet and keep working.
Free, No Registration
Every tool is free with no account, no email capture and no artificial limits. Because processing happens on your device, there are no server costs to pass on to you — the only limit is your browser's memory.
Built for Sensitive Work
PDF redaction, PII scrubbing, metadata removal and log analysis are designed for lawyers, healthcare workers, and security teams who cannot send confidential files to third-party servers — GDPR- and HIPAA-sensitive workflows welcome.
Two ways to process a file
The difference between a traditional online converter and InBrowserTools is where your file physically goes.
The traditional way
Your file travels to a company's server, gets processed there, and a copy exists outside your control — you're trusting their retention policy and their security.
The InBrowserTools way
The tool's code comes to your browser — your file never leaves it. Processing runs on your own CPU, the result downloads from memory, and closing the tab erases everything. There is no server copy because there is no server step.
