Convert ICO to PNG

Output is typically roughly 140× larger.

  • Files stay on your device
  • No upload, no waiting
  • No sign-up, no watermark

How it works

  1. Add your ICO file

    Drag a ICO file onto the drop zone, or click to browse. You can select several at once.

  2. Choose your settings

    PNG is lossless, so there is nothing to configure — the output matches the input pixel for pixel.

  3. Download the PNG

    Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.

Questions

Which resolution comes out of a multi-size ICO?

The browser picks when it decodes the file, and in practice that means the largest image the ICO contains. Most favicons top out at 32 or 48 pixels, and older ones at 16, so do not expect to recover a large logo from one. If you need a big version, go back to whatever artwork the icon was originally made from.

Will converting ICO to PNG make the file smaller?

Usually, yes. A 12-megapixel photo is around 100 KB as ICO and around 14 MB as PNG — roughly 140× larger. Because PNG is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.

Does converting ICO to PNG lose quality?

No. PNG is lossless, so every pixel decoded from your ICO file is stored exactly. Both formats are lossless, so the conversion is pixel-for-pixel identical.

Is transparency preserved when converting ICO to PNG?

Yes. Both ICO and PNG support an alpha channel, so transparent and semi-transparent pixels carry across unchanged — a logo with a cut-out background stays cut out, and soft drop shadows keep their gradient rather than picking up a white halo. Because PNG is lossless, the alpha channel is stored exactly as it was.

When should I use PNG instead of a smaller format?

Use PNG when exactness matters more than size: screenshots, logos, diagrams, UI assets, anything with sharp text, and any image you will re-edit repeatedly. Lossless means no artefacts and no cumulative degradation. For photographs on the web, WebP or AVIF will be several times smaller at quality nobody can distinguish.

About ico to png

Why people convert ICO to PNG

Extracting an existing favicon so it can be edited, reused at a larger size, or rebuilt as a modern icon set.

PNG is the right editing target: lossless, transparent, and readable by every editor. Modern sites usually want a 180 × 180 PNG for Apple touch icons and an SVG for the tab icon, with favicon.ico kept only as the legacy fallback.

Worth knowing: An ICO bundles several resolutions in one file, and this extracts one of them. If the result is a 16 × 16 image, the icon simply did not contain anything larger — you cannot enlarge it without redrawing.

On a typical 12-megapixel phone photo, the PNG output comes out roughly 140× larger than the ICO original. These are order-of-magnitude figures for one kind of image — your own results will vary a great deal, because flat colour, text and line art behave nothing like photographic detail.

What to watch out for

  • Very large files for photographic content
  • No animation (APNG is a separate, less-supported extension)
  • Slower to decode than JPEG at the same pixel count

About the two formats

ICO is a container rather than a codec: it bundles the same icon at several sizes — typically 16, 32, 48 and 256 pixels — so the operating system or browser can pick the right one. Its remaining job is the favicon at the root of a website, and Windows application icons.

PNG stores every pixel exactly as it was, with no generation loss no matter how many times you re-save it. That fidelity is why it dominates screenshots, logos and UI assets, and also why it is the wrong choice for photographs — lossless compression simply cannot get a 12-megapixel photo down to a reasonable size.

Other conversions

Everything runs on your device — nothing is uploaded, so there is no size limit, no queue and no copy left on a server afterwards. There is more on how browser-based conversion works if you want the detail. Otherwise, browse every image tool, or convert PNG back to ICO.
