How to convert PNG to ICO

The PNG is decoded on your device and re-encoded as ICO with the browser's own graphics engine. Because nothing is uploaded, even dozens of photos convert quickly and privately. ICO is the icon format used for favicons and Windows application icons.

Step 1: Choose your PNG file
Drag and drop a .png file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Convert to ICO
Each image is converted to ICO immediately.
Step 3: Download the ICO
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

The icon contains 16, 32, 48, 64, 128 and 256 px sizes, which is what Windows and browsers expect for favicons and app icons.
Photo metadata (EXIF, GPS location) is removed from the converted image, which is good for privacy.

About the formats

What is PNG?

PNG (Portable Network Graphics) is a lossless image format created in the mid-1990s as an open replacement for GIF. It keeps every pixel exactly as it was and supports an alpha channel, so images can have smooth, partial transparency. Photos saved as PNG are much larger than the same photos as JPG.

Use PNG for logos, icons, screenshots, diagrams and any image with sharp edges, text or a transparent background. For photographs where file size matters, JPG or WebP are usually better choices.

What is ICO?

ICO is the icon file format used by Microsoft Windows for programs, shortcuts and folders. A single ICO file can contain the same image at several sizes and colour depths, such as 16×16, 32×32 and 256×256 pixels, so the system picks the best one for each context. It supports transparency, and modern ICO files can embed PNG images inside.

Use ICO for Windows application icons and for favicon.ico, the small icon browsers show in tabs and bookmarks. Include several sizes so the icon stays sharp everywhere. For other purposes, a PNG or SVG is easier to work with.
