About Toolkit

Toolkit is a collection of 76 free browser-based utilitiesfor developers, writers, designers, and anyone who needs to get things done.

Why Toolkit?

Most online tools require you to:

Create an account
Upload your files to their server
Wait for the server to process
Download the result
Trust them with your data

We do it differently.

Our Principles

Every tool runs entirely in your browser. Your files, text, and data never leave your device. No upload. No server. No tracking.

⚡ Fast by Default

Static pages load in milliseconds. No backend means no network latency — tools respond instantly.

🆓 Free Forever
