When the Image to ICO Converter seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The icon looks stretched
Use a square source image - non-square art is squeezed into the square icon frame.
The icon is blurry in Explorer
Start from at least 256px; small sources cannot fill the larger sizes.
Background is solid white
JPG has no transparency - use a PNG with an alpha channel as the source.
Windows still shows the old icon
Icon caches are stubborn - refresh the icon cache or restart before judging the result.
The .ico was rejected by a tool
Some tools require specific sizes - include the classic 16, 32, 48 and 256 pixel set.
Rounded logo corners look cut
Add padding inside the square canvas so the artwork is not clipped by the frame.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- 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
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
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.
