Is my ICO file uploaded to a server?

No. The entire extraction runs in your browser using JavaScript. Your file never leaves your device.

Why does my ICO only show one size?

Some ICO files contain only a single image, especially older favicons or icons created from a single source. The tool extracts all images present — if only one appears, that is all the ICO contains.

The extracted PNG looks blurry — why?

Small ICO images (16×16, 32×32) are inherently low resolution. They are pixel-art icons designed to be viewed at their native size. Scaling them up will always appear blurry. The 256×256 image, if present, will give you a sharp large version.

Can I create an ICO file from PNG?

Yes — use our Favicon Generator to create a multi-size favicon PNG, or resize an existing PNG to the standard favicon dimensions.

Why do some ICO files have no 256×256 image?

Older ICO files created before Windows Vista (2007) typically only contain sizes up to 48×48. The 256×256 PNG-embedded format was introduced in Vista. Older icon sets will only yield small BMP-encoded images.

Can I batch-convert multiple ICO files?

This tool processes one ICO file at a time and extracts all sizes within it. For batch processing many ICO files, a command-line tool like ImageMagick (convert icon.ico output.png) is more efficient.

Why Extract PNG from ICO?

ICO files are favicon containers that bundle multiple image sizes (16×16, 32×32, 48×48, 64×64, 128×128, 256×256) into a single file. Browsers pick the right size automatically, but if you need one of those images as a standalone PNG — for a design file, presentation, or to identify a website's icon — you need to extract it. This tool reads the ICO binary, finds every embedded image, and lets you download each one as a clean PNG.

Standard ICO Sizes

Size	Typical Use
16×16	Browser tab favicon, bookmarks
32×32	Windows taskbar, address bar
48×48	Windows desktop shortcut
64×64	High-DPI taskbar icons
128×128	macOS dock icons
256×256	Windows Vista+ high-res icons

How ICO Files Work

Modern ICO files embed each image either as a standard PNG (for 256×256 and sometimes 128×128) or as a Windows BMP/DIB (for smaller sizes). This tool handles both formats — BMP-encoded images are decoded and rendered to canvas before being exported as PNG.

Common Reasons to Extract PNGs from ICO Files

Brand asset recovery — if you only have a website's .ico file and need a standalone PNG logo for design work.
Favicon resizing — extract the 256×256 version from an ICO to use as the base for creating Apple touch icons (180×180) or other sizes.
Cross-platform icon use — ICO is Windows-specific; PNG works everywhere. Extract and use the PNG on macOS, Linux or in web projects.
Design reference — inspect a competitor's favicon at full resolution to understand their branding approach.
Presentation assets — paste a company logo PNG extracted from its favicon into a slide deck or document.

ICO vs PNG vs SVG for Favicons

The browser support landscape for favicons has evolved significantly. Modern browsers support all three formats. For most sites today, a 32×32 PNG favicon is sufficient — add a 180×180 PNG for Apple touch icons and optionally an SVG favicon for automatic dark-mode support. ICO is still recommended only if you need to support Internet Explorer. Use the Favicon Generator to create new favicon files from scratch.
