QuickTools.one is a collection of free online tools for everyday file tasks. Merge PDFs, compress images, convert video to GIF, generate favicons, and more. The key difference: everything processes locally in your browser. Your files never leave your device. The Problem Most online tools upload your files to remote servers. You don’t know who sees them, how long they’re stored, or what happens to them. Many require account creation, bombard you with ads, or limit free usage to push premium plans. The Solution QuickTools.one runs entirely in your browser using modern web technologies. When you merge a PDF or resize an image, the processing happens on your device. No server ever touches your files. No accounts needed. No upload limits. No watermarks.
