I got tired of sketchy "free converter" sites that upload your files to who-knows-where before doing anything. So I built QuickTools: 20+ tools where every single thing runs client-side. Paste a JWT into a formatter? It never touches my server, because there is no server.
What's in it:
- HEIC to JPG converter (batch, for iPhone photos) — uses heic2any
- Strong password generator — uses WebCrypto, not Math.random
- Image compressor / resizer / to-PDF / PDF merger — pdf-lib for the PDF work
- Word counter, case converter, text cleaner, extractive text summarizer
- Percentage, age, salary, compound interest, discount calculators + a "days from today" date cluster
The whole thing is static — no build step, no backend, no database. Everything is verifiable in dev tools: open any tool, watch the network tab stay silent. Hosting is free (GitHub Pages), so the tools stay free.

(Not affiliated with Picsart's QuickTools — just an unlucky similar name.)
I'd genuinely like feedback: which tools are actually useful, and what should I add next? The password generator and the HEIC converter are the ones I'd bet on.
