ICO to PNG Converter

Convert a Windows ICO file into a PNG you can open, edit or use anywhere. One thing worth knowing before you start: an ICO usually contains several images at different sizes, so this extracts the largest one — which is almost always the one you want.

How to convert ICO to PNG in 3 steps

  1. Add your ICO file

    Drag it in or click to browse.

  2. Nothing to configure

    PNG is lossless and transparency carries over automatically.

  3. Download

    You get the largest image the icon contained.

Format comparison

ICO vs PNG

ICO (Windows Icon)

Multi-size icon

Bundles several sizes of the same small image in one file, for Windows icons and website favicons.

  • Several icon sizes in a single file
  • Understood by every browser as a favicon
  • Only for small images — each entry is at most 256 × 256 pixels

PNG (Portable Network Graphics)

Lossless

Stores every pixel exactly as it was saved, so nothing is lost however often the file is opened and saved.

  • Pixel-perfect: ideal for screenshots, logos and text
  • Supported everywhere, including every browser
  • Photographs make large files — often several times the JPG size

Converting from ICO is less straightforward than it looks, because an ICO is not a single image.

It is a container. A typical favicon holds four separate pictures — 16×16, 32×32, 48×48 and 256×256 — each stored complete and independent. Whatever displays the icon picks the size that suits the context: a browser tab takes the 16, a desktop shortcut takes the 48.

So "convert this ICO to PNG" has no single correct answer. This tool takes the largest image in the file, which is what people almost always want — it has the most detail and can be scaled down, whereas the small versions cannot usefully be scaled up.

Two consequences worth expecting:

  • You may get a smaller image than you hoped. If the icon only ever contained 16 and 32 pixel versions — common for older favicons — then 32×32 is the most that exists. No conversion can produce detail that was never in the file.
  • The small sizes are often not just scaled copies. Careful icon designers redraw at 16×16 rather than shrinking, because fine detail turns to mush at that size. If so, the versions inside a single ICO can look meaningfully different from one another, and you are getting the detailed one.

Transparency is preserved exactly. Icons are almost always transparent around the edges, and PNG carries that across including soft, partially transparent pixels — which is why PNG is the right target here and JPG is usually not.

Quality

Quality and file size

There is no quality setting. Both formats store their pixels losslessly, so the PNG contains exactly the image that was inside the icon — nothing is recompressed or degraded.

The size of the result depends entirely on what the icon happened to contain:

  • A modern, well-made favicon usually includes a 256×256 version, so you get a genuinely usable image.
  • An older favicon may top out at 32×32 or 48×48.
  • An application icon extracted from Windows software often includes 256×256 and sometimes larger source art.

Do not enlarge the result hoping for more detail. A 32×32 icon scaled to 512 is a blurry 512-pixel image — the information simply is not there. If you need a large version of a logo, find the original artwork rather than upscaling an icon.

If you need a specific size smaller than what you get, resize the PNG afterwards. Downscaling works well.

Why people convert icons to PNG

  • Editing an existing favicon when the original artwork has been lost — extract, edit, and convert back to ICO.
  • Using an app icon in a document, a presentation or a help guide.
  • Design and asset work, where ICO is awkward and PNG is what every tool expects.
  • Web use. Browsers display ICO in a tab but it is a poor choice for an image on a page; PNG belongs there.
  • Inspecting what an icon actually contains at full size.

ICO's awkwardness elsewhere

ICO is well supported by Windows and by browsers as a favicon, and poorly supported almost everywhere else. Design tools often will not open it, upload forms reject it, and it is not a sensible format for an image inside a web page. That mismatch is the usual reason for this conversion.

Round-tripping an icon

A common workflow is to extract, redraw, and rebuild:

  1. Convert the ICO to PNG here.
  2. Edit the PNG — ideally at 256×256 or larger.
  3. Convert back to ICO, which rebuilds the full multi-size set.

Worth noting: rebuilding generates every size by scaling from your edited image. If the original icon had a hand-drawn 16×16 version, that hand-tuning is lost — the new 16 is a scaled version of the large one. For a detailed logo that can be a visible downgrade in a browser tab, so it is worth checking the result small before replacing the old file.

PNG or JPG?

PNG, essentially always. Icons are transparent around the edges and JPG cannot store transparency, so converting to JPG puts a solid rectangle behind your icon. They are also small, flat-coloured images — exactly what JPEG compression handles worst. Choose JPG only if something specifically demands it.

Privacy

What happens to your file

This tool runs on our server, so it works the same on every phone and computer. Your file is uploaded, and this is exactly what happens to it:

  • Stored outside the public web root under a random name, never under your file's name.
  • Processed, with the original upload deleted immediately — whether it succeeded or failed.
  • The result sits behind a signed link that only you receive, which stops working after 20 minutes, and the file is deleted the moment you download it.
  • Anything never collected is deleted automatically within 30 minutes.
  • The image itself is never logged or kept. If a conversion fails, we record the formats involved and the error — not the file.
  • Camera metadata, including any GPS coordinates recording where a photo was taken, is removed from the result. Only the rotation needed to show the image the right way up is kept.

Questions & answers

ICO to PNG: frequently asked questions

Which image do I get if the ICO contains several?

The largest one. An ICO typically holds 16, 32, 48 and 256 pixel versions, and the largest has the most detail and can be scaled down if you need something smaller. The smaller versions cannot usefully be scaled up.

Why is my PNG only 32 pixels across?

Because that is the largest image the icon contained — common with older favicons, which often included only 16 and 32 pixel versions. No conversion can produce detail that was never in the file. If you need a large version, find the original artwork instead.

Is transparency preserved?

Yes, exactly, including soft partially transparent edges. That is why PNG is the right target for an icon — JPG cannot store transparency and would put a solid rectangle behind it.

Can I enlarge the PNG to get a bigger logo?

You can enlarge it, but it will be blurry. A 32×32 icon scaled to 512 is a soft 512-pixel image, because the detail was never captured. Track down the original artwork rather than upscaling an icon.

Can I edit an icon and convert it back?

Yes — extract to PNG, edit at 256×256 or larger, then convert back to ICO, which rebuilds the whole multi-size set. One caveat: if the original had a hand-drawn 16×16 version, that hand-tuning is lost, since the new small sizes are scaled from your edit. Check the result at tab size before replacing the old file.

Why will my design tool not open the ICO directly?

ICO is well supported by Windows and by browsers as a favicon, and poorly supported almost everywhere else. Many design tools never added it, and upload forms often reject it. Converting to PNG is the usual way around that.
