Input format
PNG image
PNG is a lossless image format that can keep transparent pixels. A square source image gives the most predictable icon result without stretching or cropping.
Output format
ICO icon
ICO is the icon format commonly used by Windows applications, shortcuts, folders, and favicon.ico files.
How to convert PNG to ICO
Upload the full-resolution PNG you have. Convertr creates one ICO image and scales it down proportionally only when a side is larger than the ICO format maximum of 256 pixels.
- 1 Upload a PNG image. Each file can be up to 1 GB.
- 2 Choose ICO as the output format and start the conversion.
- 3 Download the converted ICO file when processing is complete.
The converter does not crop or add padding. A non-square PNG stays non-square, so crop or resize it to a square first when the icon must fill a square canvas.
Create the right ICO file from a PNG
Choose a clean source image and the workflow that matches where the icon will be used.
Keep transparent backgrounds
Transparent pixels in the PNG remain transparent in the ICO output. An opaque PNG produces an opaque icon.
Start with a square PNG
Square artwork avoids a wide or tall icon. Common source sizes include 16×16 or 32×32 for browser icons, 48×48 for Windows icons, and 256×256 for a larger Windows icon.
One image per ICO file
This converter writes one image into the ICO file. It keeps source dimensions up to 256×256 and scales larger images proportionally so the longest side is 256 pixels.
Need a complete favicon set?
Use the favicon generator when you need a multi-size favicon.ico, browser PNG icons, Apple touch icons, Android icons, and a web manifest snippet in one download.
PNG to ICO FAQ
Does PNG to ICO conversion preserve transparency?
Yes. Transparent pixels in the source PNG remain transparent in the ICO output. An opaque source remains opaque.
What size will the ICO file be?
The ICO contains one image at the PNG dimensions when both sides are 256 pixels or smaller. Larger PNGs are scaled down proportionally so the longest side is 256 pixels.
Does the ICO contain multiple icon sizes?
No. This PNG to ICO converter writes one image into each ICO file. Use the favicon generator when you need a multi-size ICO and a full website icon set.
Can I convert a non-square PNG to ICO?
Yes. The output keeps the source aspect ratio and does not crop or add padding. For a conventional square icon, crop or resize the PNG to a square before converting.
Can I use the ICO as a Windows icon or favicon?
Yes. ICO files are commonly used for Windows shortcuts, folders, desktop applications, and favicon.ico. The application or website still needs to reference or install the downloaded file.
Is this PNG to ICO converter free?
Yes. Convertr is free to use with no registration or software installation. Uploaded files are processed for conversion and automatically deleted afterward.
