Real-world examples

Shipping an API change

A backend engineer pastes a response payload into Crop Image to get it readable, then switches to Convert Image to confirm the change behaves the way the ticket describes. Two tabs, under a minute, nothing uploaded.

A file arrives from a client in the wrong shape. Convert Image handles the conversion or check, and Crop Image produces the tidy version you actually send back. Because both run locally, client data never leaves the laptop.

Debugging in a hurry

Production is throwing an error and you have a blob of data and no context. Crop Image tells you what you are looking at; Convert Image tells you whether it is correct. Together they replace a much heavier desktop toolchain.
