About AppNimbus

AppNimbus is a set of free tools for people who build apps and websites. We focus on the small, repetitive jobs that come up every time you ship something: resizing icons, making store screenshots, writing a privacy policy, compressing images and so on.

How the tools work

Every tool runs entirely in your web browser. When you add an image or fill in a form, the work happens on your own device — nothing is uploaded to our servers. That makes the tools fast, and it means your unreleased designs stay private.

How the site is funded

The tools are free and need no account. The site is supported by advertising.
