I accidentally built an online toolbox during my Easter holiday downtime. 🐣

What started a while back as a local dev tool just for my own use kind of grew into a full little web app —so I decided to polish it and share it with everyone else who might benefit from it.

In a nutshell, it’s a collection of small, useful, no-nonsense browser tools for designers, developers, and other pixel people. Everything runs client-side (no uploads, no tracking), and it’s totally free — no signups, no ads, no nothing.

Here’s what’s available so far:

✅ Image Compressor with batch support

✅ PDF Compressor that can reduce a PDF by 90%+

✅ HEIC Converter for those sneaky iPhone photos

✅ PDF-to-Images Converter for separate JPGs

✅ WebP Converter to shrink and modernize your images

✅ Color Range Generator for automatic tints and shades

✅ Color Tester to preview colors in different contexts

✅ Contrast Checker using the WCAG standard

✅ Mesh Gradient Generator. If you hate your battery

✅ Placeholder Text Generator with smarter “language”

✅ Favicon Generator with instant preview

✅ QR Code Generator that outputs crisp SVGs

✅ Loader Maker with a TON of customizations

✅ A small snippets library with shell commands etc.

Tech-wise, it’s built in React/Next.js with an approx. 50/50 split between my own coding, and AI coding. It’s still a bit rough around the edges — it’s a side project, after all — so if you have any feedback or suggestions, I’d love to hear it ✌️

I’ve called it TonniTools, and it’s now live and free for all at → www.tonnitools.com
