ICO to PNG Converter

ICO files hold Windows icons and website favicons, but most editors, design tools and document apps cannot open them. This converter extracts the icon as a PNG image with its transparent background, so you can reuse it anywhere.

What is a ICO file?

ICO is the Windows icon format, best known for website favicons (favicon.ico). Few image editors, design tools and web platforms can open or edit ICO files directly. Modern websites often provide PNG icons alongside or instead of favicon.ico. Extracting an icon as PNG makes it easy to reuse in documents, presentations and design work.

Why choose PNG?

PNG is a lossless format: pixels are stored exactly, so text, lines and flat colours stay razor-sharp. Choose PNG for graphics with sharp edges, few colours or transparency, and whenever exact pixels matter. PNG supports full alpha transparency, which is why logos, icons, interface elements and cut-outs are usually saved as PNG. PNG files of photographs are large, often three to ten times bigger than a good JPG of the same picture.

What changes when you convert ICO to PNG

An ICO can store several sizes of the same icon. Your browser decodes the file and hands the tool one of those images, usually the largest one stored, and that image is written as PNG with transparency intact. Nothing is scaled unless you ask: open Resize to make the icon smaller or larger, keeping in mind that enlarging a small 16 or 32 pixel icon makes it blurry. At 100% quality the PNG is lossless; the default 90% uses palette compression, which suits icons perfectly because they rarely use more than 256 colours.

How to convert ICO to PNG

1. Drop your ICO files onto the upload area, click to browse, or paste an image with Ctrl+V. You can add many files at once, up to 80 MB each.
2. In Convert to, PNG is already selected; you can switch between JPG, PNG, WebP and AVIF at any time and the preview updates instantly.
3. Set the Quality: 100% writes a lossless PNG with every pixel kept, while lower values (the default is 90%) apply smart palette compression with 256 colours or fewer, which keeps transparency and makes the file smaller.
4. Transparency is kept automatically in the PNG output, so logos and cut-outs stay transparent.
5. If needed, open Resize (exact size, maximum size or percentage) and More options for a DPI value and a file-name pattern.
6. Compare the original and the result with the before/after slider, then download each file or click Download all (ZIP).

Tips for the best result

• If the result is tiny, the ICO probably only contains small sizes; look for a larger source such as an SVG or PNG logo instead of enlarging it.
• Creating a new favicon set from a logo? Use the favicon generator.
• Have the logo as a vector? The SVG to PNG converter renders it at any size without blur.
• Printing the result? Under More options you can write a DPI value (72 to 600) into JPG and PNG files without changing the pixels.

Private, free and fast

The conversion runs entirely on your device: your browser reads the ICO images, draws them on a canvas and encodes the PNG files locally. Nothing is uploaded to a server, so private photos and client work stay on your computer. There is no sign-up, no watermark and no daily limit, and settings changes are applied live to every file in the list.
