About KeepItLocally

Every day, people paste API tokens into random websites, upload contracts to "free PDF converters," and send personal photos to compression services — trusting a stranger's server with data that never needed to leave their computer.

KeepItLocally is built on a simple idea: modern browsers are powerful enough to do all of this locally. Every tool on this site — merging PDFs, OCR, image conversion, JWT decoding, all 49 of them — runs entirely in your browser using WebAssembly and JavaScript. There is no backend. There is nothing to upload to.

Privacy by architecture, not by promise

"We don't store your files" is a promise. A static site with no backend and a Content-Security-Policy that blocks third-party requests is architecture — your browser enforces it, and you can verify it yourself: open DevTools → Network while using any tool, or disconnect from the internet once a tool has loaded. It keeps working.

What the site does measure is small and listed in the privacy policy: anonymous page-view counts, and the request logs any web host keeps. None of it includes your files.

Free browser tools, no account required

Every tool on this site is free to use, with no account and no usage limits. It is built on excellent open-source software — see Licenses for credits. How the service may change over time is covered in the terms of use.
