A little less busywork.

Schwapps is a collection of 99 free utilities for writing, web work, images, and everyday calculations. Each tool does a focused job directly in your browser. There are no accounts, subscriptions, or installed extensions. Results should be reviewed before use in important work.

What happens when you use a tool

Text transformations and calculations run in JavaScript on your device. Image tools draw your chosen file into a browser canvas and export a new copy. Tool inputs are not sent to a Schwapps server. You choose whether to copy or download the result; keep your originals until you have checked it.

Understand the result

Each tool includes usage instructions and limitations. The guides walk through concrete tasks such as sizing a blog image or preserving transparency. Browser tools have limits: number precision, image encoding, and text rules can affect the output. Check the page’s notes before using a result in another system.

Help improve a tool

Send a reproducible example to Schwapps support: include the tool, browser, expected result, and actual result. Use made-up data rather than private files or credentials. The project’s source code describes how the utilities work.
