REAL WORKFLOWS

Start with the task you need to finish

These three workflows show where to begin. Each tool page also explains its steps, a concrete example and important limits so you can judge the output.

01

Prepare an image before sharing

Scale and compress a large photo before sending it. If the destination rejects HEIC, convert it to JPG. You can also sample colors from the original for a page design.

02

Clean up pasted text

For a copied list or log fragment, remove empty lines before removing duplicates. Counts help you verify the result. Use the JSON formatter when the content is structured data.

03

Debug an API with browser rules in mind

The HTTP builder shows responses from CORS-enabled APIs. Use the WebSocket tester for live messages, or convert an existing cURL command into a fetch draft.
