About this converter
Free PNG to ICO conversion, built for a real workflow.
Use this PNG to ICO converter when you need an icon container rather than a standalone image. Fileverses contain-scales the decoded PNG into four square PNG entries—16, 32, 48, and 256 pixels—with transparent padding where needed. The result is a Vista-and-later PNG-backed ICO; check it in the destination Windows or favicon workflow before relying on it.
- The ICO contains four PNG-backed entries: 16, 32, 48, and 256 pixels.
- Each entry uses contain scaling, so a non-square PNG is centered with padding instead of being cropped.
- Existing decoded PNG transparency can remain in the embedded PNG entries; the converter does not create transparency.
- This is a modern PNG-backed ICO, not a bitmap-only legacy ICO, so compatibility depends on the receiving software.
- The conversion starts from browser-decoded pixels and does not preserve the original PNG bytes, metadata, or a guaranteed output size.
How it works
Upload once.

Good to know
Questions, answered.
Is PNG to ICO conversion free online?+−
Yes. This PNG to ICO converter is free online and does not require an account or sign-up.
Does Fileverses upload my PNG?+−
No. The PNG is decoded and converted in your browser; this converter does not send it to a conversion server.
Which icon sizes are in the ICO?+−
The generated ICO has PNG-backed 16, 32, 48, and 256 pixel entries. The page does not offer a control to add or select entries.
Will a wide PNG be cropped into an icon?+−
No. Each fixed icon canvas uses contain scaling and transparent padding, so the decoded image is centered rather than cropped.
Can PNG transparency remain in the ICO?+−
Existing decoded transparency can remain because the icon entries are PNG files. The converter cannot add transparency that is not in the decoded image.
Will every program accept this ICO?+−
Not necessarily. The output uses modern PNG-backed ICO entries, so test the downloaded file in the specific Windows, browser, or application workflow that will use it.
