PNG to ICO Converter

Runs in your browser — your files are never uploaded.

Turn any PNG into a complete, ready-to-ship favicon package. OkConverter generates a multi-resolution favicon.ico plus every PNG size modern browsers and devices expect — and a site.webmanifest — bundled into a single ZIP. Everything runs locally in your browser, so your image is never uploaded to a server.

How to convert PNG to ICO

  1. 1

    Drag and drop your PNG (a square image of at least 512×512 works best) onto the box, or click to choose a file.

  2. 2

    OkConverter instantly renders every favicon size and builds a multi-resolution favicon.ico — all in your browser.

  3. 3

    Click “Download favicon package” to save the ZIP containing the .ico, all PNG sizes, and site.webmanifest.

  4. 4

    Unzip into your site root and add the linked <link> / manifest tags to your HTML <head>.

Frequently asked questions

Is the PNG to ICO conversion really free?+

Yes. Every conversion runs entirely in your browser using your own device, so there is no server cost and no usage limit. It is free and unlimited.

Are my files uploaded anywhere?+

No. OkConverter reads and converts your PNG locally in the browser. The image never leaves your device — nothing is uploaded, stored, or logged.

What is included in the favicon package?+

A multi-resolution favicon.ico (16, 32 and 48 px), standalone PNGs at 16, 32, 48, 180 (apple-touch-icon), 192 and 512 px, and a ready-to-edit site.webmanifest — all zipped together.

What size should my source PNG be?+

Use a square PNG at 512×512 or larger for the sharpest results. Smaller or non-square images still work, but will be scaled to fit each square favicon size.

Does the .ico work in older browsers?+

Yes. The .ico embeds standard PNG-compressed images, which every browser since Internet Explorer 11 and all modern browsers support.
