About LocalKit

LocalKit is a collection of small, focused tools for everyday file and text tasks — compressing images, converting formats, merging and splitting PDFs, generating QR codes, converting JSON to TypeScript and more.

How it works

Every tool on this site is a piece of JavaScript that runs inside your browser. When you drop in a file, your browser reads it from your device, processes it in local memory and hands the result back for download. There is no upload step — we physically can't see your files, because they are never sent anywhere.

This design has three nice consequences: your data stays private by default, results are instant regardless of file size, and the site costs almost nothing to run — which is why everything is free.

Why we built it

We got tired of "free" converter sites that upload your documents, watermark the output, cap you at two files a day and hide the real limits behind a subscription. LocalKit does one thing differently — local processing — and everything else follows: no sign-up, no watermarks, no artificial limits.

Open source & credits

LocalKit stands on the shoulders of open source: PDF.js, pdf-lib, docx, JSZip, html2canvas, jsPDF, docx-preview and qrcode-generator — and draws inspiration from it-tools and omni-tools. Thank you, open web.
