About this tool
Converting PNG to ICO is the standard way to make a favicon for a website or an icon for a Windows program or shortcut. Transparency is kept.
PNG is lossless and supports transparency, which makes it ideal for screenshots, logos, icons and graphics with sharp edges or text. For photographs it produces much larger files than JPG or WebP.
ICO is the Windows icon format, and the classic format for website favicons (favicon.ico). One ICO file holds the same icon at several sizes so it looks crisp in browser tabs, bookmarks and on the desktop.
The icon is made square (the image is centred on a transparent background if it isn't square already) and saved at 16, 32, 48, 64, 128 and 256 pixels in one file, each stored losslessly. For the sharpest result, start from an image at least 256 pixels wide.
Frequently asked questions
Can I convert multiple PNG files to ICO at once?
Yes. Select or drop as many PNG files as you like; each is converted to ICO and you can download them individually or all together as a ZIP.
Which sizes are included in the ICO file?
16×16, 32×32 and 48×48 for browser tabs and Windows, plus 64, 128 and 256 pixel versions when the source image is large enough. Browsers and Windows automatically pick the best size.
What happens to the photo's metadata (EXIF, GPS location)?
The new file is encoded from the image pixels only, so camera details and GPS location stored in the original are not copied over. The photo is rotated correctly before that, so it won't come out sideways.
Are my images uploaded to a server?
No. The image is decoded, processed and re-encoded entirely inside your browser using WebAssembly. Nothing is sent to us or anyone else, which also makes it fast — there is no upload or download wait.
