How to Convert PNG to ICO Online
Follow these three simple steps to create an ICO icon or favicon from a PNG image.
Add a PNG Image
Select a PNG logo, symbol, or image from your device. You can also drag and drop your PNG files into the converter.
Choose the ICO Size
Choose an icon size such as 16×16, 32×32, 48×48, or 256×256 pixels, or enter custom dimensions. The default size is 32×32.
Convert and Download
Start the conversion, preview the ICO result, and download it. If you added multiple PNG images, you can download the completed files together as a ZIP file.
How Does the PNG to ICO Converter Work?
The CompressFly PNG to ICO converter turns PNG images into ICO files at the width and height you select, directly in your browser. Unlike online converters that require file uploads, CompressFly handles image conversion with modern browser technology. No files are sent to a server: everything is processed locally, individually or in bulk. Smart image conversion makes changing formats simple and free, with no signup required.
What "in your browser" means
- Your PNG files are not uploaded to a server
- Conversion runs locally on your device
- Converted ICO images are downloaded directly from your browser

Easy to Use

Preview Before Downloading
Review each converted ICO image and its output file size before downloading it to your device.
Private & Secure
Your PNG files are processed locally in your browser and are not uploaded to a server.
Create a Favicon from PNG
Turn a PNG logo or symbol into an ICO favicon for your website. Simple artwork with a clear shape remains easier to recognize at small sizes. A square image helps keep the icon proportions consistent; use Crop Image first if you need to adjust the composition.
Choose the icon dimensions you need, generate the ICO file, and add it to your website through its favicon settings or an icon link in the page head. The converter creates the icon file; it does not install the favicon on your website.

Upload the downloaded ICO through your website platform's favicon settings, or place it on your website and reference its path in the page head, for example <link rel="icon" href="/favicon.ico">. The file path must match where you saved the icon.

Is there a file size limit, and are my PNG images uploaded?
Your PNG images are processed locally in your browser and are not uploaded to a server, so there is no server upload limit. The practical limit depends on your device's available memory and processing power, especially for very large images or batches.
