How to convert PNG to ICO
Here's how to turn your PNG files into ICO:
- Add one or more PNG files — drag and drop them or click to browse.
- Click Convert to ICO and let the conversion run in your browser.
- Download your new ICO files individually or as a batch.
What is PNG?
PNG is a lossless image format that preserves every pixel exactly and supports a full alpha-transparency channel. It is the standard choice for logos, icons, screenshots and any graphic with sharp edges, flat colour or transparent areas.
What is ICO?
ICO is the icon container used by Windows and by websites for the favicon shown in browser tabs. A single ICO file can hold several sizes (16×16 up to 256×256) so the right resolution is always available.

Why convert PNG to ICO?
People convert PNG to ICO to get a format that fits website favicons and windows application icons — and to make the file easier to open, share and reuse.
What ICO gives you: holds multiple sizes in one file, native Windows and browser support and supports transparency.
Where PNG falls short: much larger than JPG for photographs, no animation and not ideal for print colour profiles. Converting keeps your content while moving to a format that matches where the file is going.
Tips for the best results
- ICO is lossless, so your converted files keep every detail of the original PNG.
- You can convert several files in one go — add as many PNG files as you like and download them together.
- Everything runs locally in your browser, so even large files convert quickly and nothing is uploaded.
