Free Online Tools is a small collection of browser-based utilities for developers and everyday tasks. Each tool runs entirely as JavaScript in your own browser — nothing you type, paste, or upload is ever sent to a server, so it's safe to use with sensitive text, images, or documents. There's no sign-up, no installation, and no limit on how many times you can use them.
