What is this Universal Cookie Converter?
Our free online Cookie Converter is a vital tool for digital marketers, web scrapers, and developers. When purchasing or transferring accounts, session cookies are often exported in raw Netscape format (.txt). However, modern anti-detect browsers like Dolphin Anty, AdsPower, and Multilogin often require cookies to be strictly formatted in JSON.
This intelligent script works 100% locally in your browser ensuring maximum privacy. It auto-detects your pasted format, automatically removes dead or corrupted lines (invalid domains or missing names), and converts it to the opposite format instantly.
Auto-Minify JSON Feature: If you paste a heavily formatted, multi-line JSON payload, our engine will automatically compress and minify your input into a single raw line to save screen estate, while simultaneously providing the structured Netscape strings in the output window.
