The last "free online tool" site you'll ever bookmark

Most "free online tool" sites upload your files to their servers, slap a watermark on the output, and ask you to sign up for the full version. QuickUtil doesn't. Every single tool on QuickUtil runs entirely in your browser. PDFs are merged locally. Images are compressed locally. Passwords are generated locally. Your data never touches a server — because there's no server involved.
Hey Product Hunt!
The idea started from a personal frustration: every time I needed a quick tool — merge a PDF, check a BMI, generate a QR code — I'd land on a site that either wanted me to create an account, had a file size limit, or was uploading my files to some server I knew nothing about. I didn't want to sign up. I didn't want my files leaving my device. I just wanted the tool to work. So I built QuickUtil with one hard constraint: nothing uploads, ever. Every tool runs entirely in your browser using native APIs — Web Crypto for hashing, Canvas for image processing, PDF.js for documents. The server literally can't see your data because it never receives it.
What started as "I'll build 10 tools over a weekend" turned into 64 tools across 11 categories in a few days. The scope kept expanding because every time I built one tool, I'd think of three more people actually need.
Features I'm Proud Of
The JWT Decoder that inspects tokens with expiry countdowns — without sending your tokens anywhere.
The Mortgage Calculator with a full amortization SVG chart and extra-payment savings — built with zero charting libraries.
The Readability Checker that computes 6 academic scores (Flesch, Gunning Fog, SMOG, ARI, Coleman-Liau) in a single pass.
The roadmap is aggressive — aiming for 150+ tools. Phase 3 is already in progress.
Would love to hear which tools you use most, and what's missing that you wish existed. Every feature request goes straight into the backlog.
Thanks for the support!
