I built 90+ free browser tools at beginthings.com -- here is the tech behind it

I have been building beginthings.com, a collection of 90+ free browser-based tools. Everything runs client-side with no server processing needed for most tools. Here is a quick overview of what is available and some of the technical thinking behind it. What is beginthings.com? A free, no-signup, no-ads collection of browser tools. Think of it as your utility belt for common tasks that developers, designers, and content creators run into daily. Some of the tools available For Developers: JSON formatter and validator Base64 encoder/decoder Password generator QR code generator Lorem ipsum generator For Designers: Color palette generator Gradient creator Image compressor Image format converter For Content Creators: Word counter Character counter Text case converter General Utilities: Unit converters Calculator tools File converters Why client-side? Privacy and speed. Your files never leave your browser. An image you compress on beginthings.com is processed entirely on your device using Jav
