Toolbench is a toolkit of everyday converters — time zone, unit, currency, CSV/JSON, PDF & DOCX tools (merge, split, images→PDF, DOCX→PDF, PDF→DOCX), plus two AI tools: image upscaling and OCR text extraction. Everything runs entirely in your browser. No signup. No file uploads. No ads. Your files never touch a server — even the AI features run on in-browser models, not an external API. Built solo as a side project. Feedback welcome, especially on the AI tools and PDF/DOCX conversions.

Hey Product Hunt 👋 Maker here. I built Toolbench because I kept needing quick converters (time zone math, unit conversions, merging a couple PDFs) and was tired of ad-heavy sites that make you wait through a countdown timer or upload your files somewhere. Everything here runs client-side — pdf-lib, mammoth.js, and pdf.js do the heavy lifting entirely in your browser. Nothing you upload or paste is ever sent to a server. It's free, no account needed. Would genuinely love feedback — especially if you try the PDF/DOCX tools on a real file and something breaks or looks off. That's the part I'm least confident about and most want to improve.
