About Us

Avuis is a free collection of online tools built for one thing: getting a small task done quickly, without friction.

What we offer

Avuis hosts 150+ tools across a range of categories, including image editing, unit conversion, online calculators, text content utilities, developer tools, binary converters, and website management tools. Whether you need to resize an image, convert a measurement, format some JSON, or check on a website, you'll find a tool for it here.

How it works

• No account, no sign-up, and nothing to install — every tool runs directly in your browser.
• Most tools process your input locally in your browser. Where a tool needs our server (for example, some image operations), your input is used only to produce your result and is not kept afterwards — see our Privacy Policy for details.
• All tools are free to use, for personal and commercial work alike.

Why it's free

Avuis is supported by advertising. This lets us keep every tool free to use and cover the cost of running the site, without charging for access or selling your data.
