Why Client-Side Processing?

Most online converters upload your sensitive files to a remote server. We don't. By leveraging advanced WebAssembly technologies, we process everything locally on your machine.

100% Private

Your documents never leave your computer. We cannot see, store, or share your files because they are never uploaded to our servers.

Lightning Fast

No upload or download wait times. Processing happens instantly using your device's processing power, restricted only by your CPU.

Offline Capable

Once the page is loaded, our PWA technology allows you to use the tools without an active internet connection. Perfect for travel.

The Technical Difference

How we compare to traditional online tools

Traditional Converters

You
Upload
Server
Download
File

Your file leaves your device, travels the internet, and gets processed on someone else's computer.

InBrowserTools Way

Your Device Processing happens right inside your browser. The file never travels anywhere.

Why we built this.

A few years ago, we needed to merge a simple PDF containing sensitive financial information. The top search results were all online converters that required uploading the file.

We hesitated. "What happens to the file after upload? Who sees it? Is it deleted?"

The privacy policies were vague, and the websites were cluttered with ads. We realized there had to be a better way. With modern browsers becoming incredibly powerful, the need for server-side processing for simple tasks like splitting a PDF or compressing an image has vanished.

InBrowserTools was born from a simple idea: Build the tools we wanted to use. Tools that respect user privacy by design, not just by policy. Today, we offer a suite of manipulation tools that are free, fast, and completely offline-capable.
