About SmaftyTools

SmaftyTools is a collection of 55+ free online utilities for developers, writers, students and anyone who needs to get a quick job done — formatting JSON, converting units, generating passwords, resizing images and much more.

Every tool runs entirely in your browser. Nothing you type, paste or upload is ever sent to our servers, because we don't have any servers processing your data — the site is a static bundle served from a global CDN. That makes the tools fast, private and available even on flaky connections.

There are no accounts, no signups, no usage limits and no paywalls. The site is supported by unobtrusive advertising, which keeps every tool free for everyone.
