How to convert PNG to ICO

  1. 1

    Choose your PNG files

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Start the conversion

    Press the convert button. Your browser converts the files in seconds.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

Generate a favicon or Windows icon from any image. The ICO file contains 16, 24, 32, 48, 64, 128 and 256 px versions so it looks sharp in browser tabs, bookmarks and desktops.

What is PNG?

PNG (Portable Network Graphics) is a lossless image format with transparency support. It is ideal for screenshots, logos and graphics with sharp edges, but files are larger than JPG for photos.

What is ICO?

ICO is the Windows icon format used for website favicons and desktop shortcuts. One ICO file can hold several sizes of the same icon.

Safe for confidential files

Unlike upload-based converters, ZapMorph processes files inside your browser tab. Your documents are never transmitted, stored or logged — close the tab and they’re gone.

Frequently asked questions

Is the png to ico converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple PNG files at once?

Yes. Select several PNG files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
