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
- Starting from a non-square PNG
- Using a small source and losing the big sizes
- Forgetting transparency on a flattened source
- Not clearing the browser icon cache after replacing
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
Why does ICO need several sizes?
Different contexts render icons at different pixels - the file carries a size for each so none has to upscale.
What PNG size should I start with?
Square, 256 pixels or larger. Bigger sources scale down cleanly into every slot.
Does transparency carry over?
Yes - PNG alpha maps directly into the ICO format.
Is my file uploaded?
No - conversion runs entirely on your device.
