QuickUtil
The last "free online tool" site you'll ever bookmark
QuickUtil launched on March 12, 2026.
What it does
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.
The private alternative to SmallPDF, TinyWow, and ILovePDF. 112+ free tools for PDF, image, developer, finance, and more — 100% client-side. Your files never leave your browser.
110 + free tools for PDF, image, developer, finance, health, and more. Every tool runs in your browser. Your files never touch our servers. Decode and inspect JSON Web Token header, payload, and signature. Calculate monthly payments, total interest, and amortization schedule. Calculate your Body Mass Index with metric or imperial units. From PDFs to finance to developer utilities — everything in one place. Evaluate options against weighted criteria to make better decisions. Calculate your 5 heart rate training zones based on your max heart rate. Calculate your daily protein, carbs, and fat targets based on your goals. Encrypt and decrypt text with AES-256 using the Web Crypto API. Check…from quickutil.io
