🔍 How your file is processed

Runs: In your browser on this page
Engine: Your browser's own image decoder and canvas encoders (AVIF included); HEIC decodes via a bundled JavaScript decoder (Emscripten-compiled libheif); GIF, BMP and ICO are written by our own encoders
Max input: 512 MB per file
Your file: Processed in this browser tab — the file is not uploaded. Converted results are kept in this browser's local storage for up to two hours so their matching download page can show them; expired results are removed on the next site visit. Nothing is stored on our servers.
Good to know: Converting to JPG or lossy WebP applies the quality level you choose. JPG and BMP have no transparency, and our GIF encoder does not carry transparency either — transparent areas are flattened to the background for all three. Animated GIF input is read as its first frame.

Why convert ICO to PNG?

ICO files cannot be opened by most editors. This tool pulls the largest image out of the icon container and saves it as a regular PNG with transparency, so you can edit, resize or reuse an icon you no longer have the source for.

What this tool preserves — and what it changes

✓ Preserved

The icon's transparency, in a normal PNG any editor opens
The largest image stored in the container — our ICO parser scans every directory entry and picks the biggest one

↺ Changed

Only one image comes out: the other sizes stored in the same ICO are not extracted
The result is a standalone PNG at the icon's stored pixel size — no upscaling is applied

Known limits & edge cases

Both storage flavors are handled: PNG-compressed entries decode directly, and classic DIB (BMP-style) entries are rebuilt with a proper BMP header — including correcting the doubled AND-mask height — before decoding
A file that is not really an ICO fails with a clear 'could not be parsed' message, and the inspection card shows what it actually is

Engine: Your browser's own image decoder and canvas encoders (AVIF included); HEIC decodes via a bundled JavaScript decoder (Emscripten-compiled libheif); GIF, BMP and ICO are written by our own encoders.

About the formats

What is an ICO file?

ICO is the icon container format used by Windows and by websites for favicons — the little icon shown in the browser tab. An ICO file can hold the same image at several sizes (16×16, 32×32, 48×48 and up to 256×256). Browsers and Windows expect this exact format, so PNG or JPG logos usually need to be converted to ICO before they can be used as a favicon or application icon.

What is a PNG file?

PNG is a lossless image format that preserves every pixel exactly as it was saved. It supports full alpha transparency, which makes it the standard for logos, icons, screenshots and any graphic that must keep sharp edges and clean text. PNG files are larger than JPG for photos, but they never lose quality no matter how many times they are re-saved.

Getting an icon back out of the .ico box

ICO is a container format most editors won’t open and most platforms won’t accept as an upload — inconvenient when the only copy of a logo you can find is a favicon, or when documentation needs a picture of an application’s icon. This tool decodes the ICO and hands you a PNG, transparency intact, that every design tool, wiki and chat app understands.

It’s a small conversion with regular real-world uses: auditing a competitor’s brand assets, rebuilding a lost logo from a site’s favicon, embedding tool icons in internal docs and runbooks, or migrating a legacy application’s resources to a modern build. Icons are small by nature — a 32-pixel source stays 32 pixels, so for print or large display you’ll want to track down the original artwork rather than upscale.

Frequently asked questions

Is this ICO to PNG converter free?

Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.

Can I convert multiple ICO files at once?

Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.

Will I lose quality converting ICO to PNG?

No — PNG is a lossless format, so the converted file reproduces the decoded image pixel for pixel. No additional compression artifacts are introduced by the conversion.
