Convert ICO to PNG Free Online — Extract Favicon Images

By Picovert Team2026-03-055 min read

ICO files are the standard format for favicons and Windows application icons. While ICO is excellent for its intended purpose, there are many situations where you need to convert ICO to PNG — to use the icon in design tools, upload it to social media, or view it in applications that don't natively support ICO. This guide covers how to convert ICO to PNG free, online, with no software required.

What Is an ICO File?

ICO (Icon) is a container format developed by Microsoft for Windows icons. Unlike JPG or PNG, a single ICO file can contain multiple images at different resolutions — typically 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. The operating system automatically selects the appropriate size based on where the icon is being displayed.

ICO files are commonly found as:

  • favicon.ico — website favicons displayed in browser tabs and bookmarks
  • Application icons — .ico files bundled with Windows programs
  • Desktop shortcuts — custom icons for Windows shortcuts
  • System icons — Windows UI elements and folder icons

How to Convert ICO to PNG Free Online

  1. Open Picovert's ICO to PNG converter in your browser. No download, no account, no file size limits for local conversion.
  2. Drag and drop your ICO file (or click to browse). The converter reads the ICO container and shows all the sizes stored inside it.
  3. Select which resolution you want to extract as PNG. For most uses, the 256×256 or 128×128 version gives the best quality.
  4. Click "Convert" and then "Download" to save the PNG to your device.

All processing happens locally in your browser — ICO files often contain proprietary corporate logos, so local processing ensures your files never leave your device.

Which PNG Size to Extract from ICO

Multi-resolution ICO files contain multiple PNG or BMP images at different sizes. Choosing the right one depends on your use case:

  • 256 × 256 px: Best for design work, printing, and general use. This is the largest size typically embedded in ICO files.
  • 128 × 128 px: Good for app store listings, social media profiles, and documentation.
  • 48 × 48 px or 32 × 32 px: Appropriate for favicon use or when you need a small icon image.
  • 16 × 16 px: Only for browser tab favicons. Very small — avoid using at larger display sizes as it will appear pixelated.

Common Uses for ICO to PNG Conversion

  • Using a favicon in designs: You've downloaded a website's favicon.ico and want to use the logo in a design tool (Figma, Canva, Photoshop). These tools don't support ICO, but they all support PNG.
  • Creating high-resolution versions: Extract the largest available size from an ICO and use it at high quality.
  • Adding app icons to documentation: ICO files don't display in browsers, Google Docs, or most content systems. Convert to PNG for use in any context.
  • Archiving or migrating icons: Converting an ICO library to PNG for use in cross-platform projects.

ICO vs. PNG for Favicons

For creating or managing favicons, it's worth understanding when to use ICO vs. PNG:

  • ICO: Required by older browsers for favicon.ico at the root of a website. Supports multiple sizes in one file. Windows still uses ICO for application icons.
  • PNG favicon: Modern browsers (Chrome, Firefox, Safari, Edge) support PNG favicons declared via <link rel="icon" type="image/png"> in the HTML head. A 32×32 or 48×48 PNG works for most browser tab uses.
  • SVG favicon: Modern browsers also support SVG favicons, which scale perfectly. Best for new websites targeting modern browsers only.

If you need to go the other direction — convert PNG to ICO — use Picovert's PNG to ICO converter.

ICO to PNG: Quality Expectations

The quality of your converted PNG depends entirely on what's stored in the ICO file:

  • Modern ICO files store full-color PNG images internally. Extracting from these produces perfect-quality PNG output.
  • Very old ICO files may store 4-bit or 8-bit color BMP images. These will convert to PNG with the same limited color depth.
  • ICO files have a maximum embedded image size of 256 × 256 px. You cannot upscale beyond what's stored. If you need larger, you would need to recreate the icon from a vector source.

Batch Convert ICO Files to PNG

If you have multiple ICO files to convert — a collection of app icons, a set of downloaded favicons, or a folder of Windows icons — you can batch convert them. Drop multiple ICO files at once into Picovert's converter and download each as PNG.
