Favicon and icon conversion

PNG to ICO | Convert PNG Icons to .ICO Free

Browsers, Windows shortcuts and classic web stacks still want .ICO files | our generator builds a real multi-resolution icon from any PNG, entirely in your browser.

Open Favicon Generator
Drop a square PNG | get a ZIP with a true multi-size .ICO, PNG favicons, manifest and the HTML snippet.

A proper favicon.ico is not one image renamed: it is a container holding 16 × 16, 32 × 32 and 48 × 48 renders so Windows taskbars, browser tabs and desktop shortcuts each get the right density. The generator encodes that container locally and packages it with the modern PNG favicons and a webmanifest.

Start from a square PNG with transparency for the cleanest result | non-square sources are centre-cropped with preview, so nothing important lands outside the icon circle.

Everything (encode, ZIP, download) happens on-device | your brand assets never leave the tab, and the output ZIP drops straight into any site root or project folder.

What sizes go inside a .ICO?
The classic trio: 16 × 16, 32 × 32 and 48 × 48 px. Modern sites also link apple-touch-icon (180 px) and PNG favicons | the generator emits all of them plus the HTML snippet.
Can I convert a JPG or WebP to ICO?
Yes | convert to PNG first with Image to JPG/WebP to PNG if you need transparency, then feed the PNG to the generator.
Is the .ICO standards-real?
Yes | a genuine ICO container with BMP-encoded frames, the format every browser and Windows shell expects, built client-side.
Is there a daily limit or watermark?
No limits, no accounts, no watermarks | process one file or fifty, all free, including commercial use.
