About FizzKit

FizzKit is a collection of focused, free, browser-based tools for developers and people who work with text, data, and code. Every tool runs 100% in your browser — there is no server-side processing, no account system, and no analytics that can identify you.

The project exists because most "online tools" sites are slow, covered in ads, and paste your data into a server you have no reason to trust. FizzKit is the opposite: fast, private, and focused on the task at hand.

Privacy policy

No tool on this site sends your input anywhere. Everything — formatting, encoding, hashing, parsing — happens on your device using the same JavaScript that your browser uses for every other website. When you close the tab, nothing about your session remains with us.

The site uses local storage in your browser for two optional features: your theme preference and a list of the tools you have recently used. You can clear both at any time from your browser's site settings.

FizzKit does not use tracking cookies, does not integrate third-party analytics with cross-site identifiers, and does not rent your browsing history to advertisers.
