When you would use this
Situations, not settings.
- Pulling artwork back out of a favicon
- The site icon is often the last copy of a small logo, and PNG gets it out with the clear background still intact.
- An app icon for a store listing
- Listings ask for PNG at a stated size. An ICO is refused on sight, even when it holds exactly the right picture.
- An icon for a design file
- Figma, Sketch and most editors will not place an ICO. A PNG drops straight in and keeps its alpha.
How it works / no cloud
A conversion engine, not an upload form.
Your browser decodes ICO, so filetity reads the icon and writes a PNG from the same pixels, alpha channel included. An ICO holds several square sizes and the browser hands back the largest, which is the one you get.
- Offline ready
- Installable app
- No file limit queue
Straight answers
No accordion. Nothing hidden.
- Is it free?
- Yes, with no watermark and no page limit.
- Does it need an account?
- No. There is no account system.
- Is my file processed on my device?
- Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- What formats are supported?
- ICO in. PNG out, one file per image, or a ZIP when you convert several.
- What are the limits?
- No image count limit. An ICO usually holds several sizes and only the largest comes out; the smaller copies are dropped. Nothing else about the picture changes, so there is no quality setting.
- Does it work on mobile?
- Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Does it work offline?
- Yes, once the page has loaded. The tool keeps working with no network connection.
- Which of the sizes inside the icon do I get?
- The largest. An ICO is a container: one file holding the same picture at 16, 32, 48 and often 256 pixels. Measured in Chrome on 2026-09-06, the browser returns the largest copy regardless of the order they are stored in, and this page converts that one.
- Is the clear background kept?
- Yes. Both formats have a real alpha channel, so the transparent area around the icon stays transparent and no white square appears behind it. That is the reason to pick PNG over JPG here.
- Can I pull out all the sizes separately?
- No. The browser hands over one image per file and it is always the largest, so the smaller copies cannot be reached from this page. If you need a particular size, convert and then resize.
- Does this work the other way, PNG back to ICO?
- Not on this site. Writing an ICO needs an encoder your browser does not have, and asking a canvas for one silently returns a PNG with the wrong extension on it. Rather than ship that, the conversion is not offered.
