Five concrete examples of the JPG Cropper in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Cutting a photo to a blog header ratio
The task: Cutting a photo to a blog header ratio. You start from a JPG photo plus a crop rectangle or target ratio.. The tool returns the selected region as a new JPG, pixel-clean and in the proportions you set., giving you a tightened composition that fits its slot and loses the distracting edges. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Removing clutter from the edges of a shot

A Full Worked Example
Input: street-scene.jpg · ratio 4:5 · drag over the subject
A 4:5 crop centred on the subject, background clutter removed.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
