Before You Generate
- Write the goal in one sentence before you open the tool.
- Gather your real material first: facts, numbers, names and constraints.
- Decide what done looks like - length, format, tone and audience.
- Set aside five uninterrupted minutes; context switching costs more than the task.

Mistakes to Avoid
- Using a non-square source and getting a distorted icon
- Starting from a small image and upscaling
- Ignoring transparency on a JPG source
- Forgetting Windows caches old icons
A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
Frequently Asked Questions
What size should the source image be?
Square and at least 256 pixels. Larger sources scale down cleanly into every icon size.
Does the ICO keep transparency?
Yes when the source is a PNG with transparency - the alpha channel carries through.
Can I include several sizes in one file?
That is exactly what ICO is for - multiple sizes live in one file so Windows can pick the right one.
Is my image uploaded?
No, conversion runs entirely on your device.
