Free PNG to ICO Converter
Turn a PNG, JPG, or WebP image into an ICO file for favicons and icons. Conversion happens in your browser.
Choose icon sizes
For a crisp icon, start with a square source image at 256 × 256 px or larger. Upscaling a small image cannot restore missing detail.
How to convert PNG to ICO online
- Choose your source image. Select a PNG, JPG, JPEG, or WebP file. A square logo or symbol with clean edges is a useful starting point.
- Select icon sizes. Choose common favicon dimensions such as 16 × 16, 32 × 32, and 48 × 48 pixels. Add larger sizes if your target workflow supports them.
- Create the ICO file. Select Convert to ICO. The tool renders each selected size on a transparent canvas and packages the icon frames into one ICO file.
- Download and check it. Save the result and test it in the website, browser, or application where you plan to use it. Multiple results can be downloaded together as a ZIP.
What does a PNG to ICO converter do?
A PNG to ICO converter creates a Windows icon file from a regular image. ICO is commonly used for website favicons and Windows shortcuts or application icons. Unlike a single PNG image, an ICO file can contain several icon sizes so compatible software can choose an appropriate version for the space available.
This tool creates an ICO container with PNG-encoded image frames for the sizes you select. That works in many modern favicon workflows, but some older software expects bitmap-encoded icon frames. If you are preparing an icon for legacy software, test the downloaded file in the target application before replacing an existing asset.
Why make an ICO file from PNG?
- Website favicons: Create a favicon.ico file from a logo or symbol for projects that request the ICO format.
- Multiple icon sizes: Include common dimensions in one file instead of managing a separate source image for every size.
- Transparent backgrounds: PNG sources with transparency can retain transparent pixels when drawn to the icon canvas.
- Desktop and application workflows: Some tools still request an ICO file for shortcuts, application icons, or site assets.
- Local processing: The image is handled by your browser; the conversion code does not upload it to a PixxelConverter processing server.
Which favicon sizes should you include?
For a typical website, 16 × 16 and 32 × 32 pixels are common small favicon sizes, while 48 × 48 pixels is useful in some desktop contexts. Larger frames such as 128 × 128 or 256 × 256 pixels may help workflows that use higher-resolution icons. Follow the requirements of the browser, operating system, or app you are targeting.
Start from the highest-quality source image you have. A tiny logo stretched to 256 pixels may look soft. If your source is rectangular, the converter fits it inside a square canvas without stretching it out of proportion; unused space remains transparent.
Quality and compatibility notes
- Converting a JPG to ICO cannot restore details lost during earlier lossy compression.
- Check transparent edges against light and dark backgrounds after downloading.
- A larger output dimension does not mean new source detail has been created.
- This converter accepts raster PNG, JPG/JPEG, and WebP files. Export SVG artwork to a raster image first.
- Keep your original image until you have checked the ICO file in its intended workflow.
Frequently asked questions
Is this PNG to ICO converter free?
Yes. Use it in a modern browser without an account. The current tool accepts up to 10 images per batch, with a maximum of 10 MB per image.
Can I convert JPG or WebP to ICO too?
Yes. The tool accepts PNG, JPG, JPEG, and WebP. If your browser cannot decode a file, export a PNG copy first and convert that.
Which sizes should I select for a favicon?
16 × 16, 32 × 32, and 48 × 48 pixels are useful common sizes. Add larger sizes if the target platform supports them.
Will the ICO file keep transparency?
The converter draws the source on a transparent canvas and packages PNG-encoded frames, so supported transparency can be retained. Check the downloaded icon in a viewer that displays transparency.
Are my images uploaded to a server?
No upload is required. The image is read and rendered in your browser, and the ICO file is assembled locally on your device.
Can I use the ICO file as my website favicon immediately?
You still need to configure the favicon in your website settings or HTML. Keep your existing favicon until you have checked that the new one works.
Does ICO always look better than PNG?
No. ICO is a container for icon images, while PNG is a general image format. Choose based on the requirements of the software or platform using the file.
