Convert PNG to ICO Online Free & Fast
Turn your PNG images into ICO files in seconds. No installs, no software just upload, convert and download.
This tool converts PNG images into ICO format, the icon format used for website favicons and Windows application icons, directly in your browser. PNG is a well-matched source for this: it already supports transparency, so a transparent background in your PNG carries over to the ICO rather than being filled in. As with any icon, the best results come from simple, high-contrast designs logos, symbols or wordmarks since icons are typically displayed very small, often 16 or 32 pixels, where fine detail tends to disappear. Upload your file and download an ICO in seconds; it's deleted automatically within an hour.

Frequently Asked Questions
Will my PNG's transparency carry over to the ICO?
Yes. Both PNG and ICO support transparency, so a transparent background in your PNG stays transparent in the resulting icon.
Will my image look good as a favicon or icon?
It depends on the design. Icons are typically displayed very small 16 to 32 pixels is common so simple, high-contrast graphics like logos or symbols work best. If your PNG is a detailed image, consider simplifying it before converting.
What sizes does an ICO file need to be?
Favicons and app icons are often needed at multiple sizes, like 16x16, 32x32 and 48x48, so the browser or operating system can pick the right one for each context. Check the requirements for your specific use case.
Is ICO the same as PNG, just renamed?
No. ICO is a distinct container format built specifically for icons, and it's typically what browsers and Windows expect for favicons and app icons rather than a standard image format like PNG.
Is there a limit on how many PNGs I can convert?
The free plan allows 10 conversions a day for files up to 10 MB. Paid plans remove the daily limit and raise the file-size cap.
Is it safe to upload my PNG files?
Yes. Conversion is automated, uploads are encrypted (HTTPS/TLS) and every file is permanently deleted within 60 minutes. Your images are never used to train AI models.
