KEEP
Original ICO and exported PNG both stay local.
No upload, no cloud, no log.
What it actually does
01
DECODE
ICO container parsed in your tab.
ICOs hold multiple resolutions (16×, 32×, 48×, 256×). We pick the largest.
02
ENCODE
PNG with the original alpha channel preserved.
Lossless. Transparent. Sharp at every pixel.
04
BATCH
Drop a folder of ICO files.
Each file's largest layer becomes a PNG.
How it works
- Open morph.cool in any modern browser.
- Drop your .ico file onto the drop zone, or click to browse.
- Pick PNG as the output format.
- Download your converted .png file. Done in seconds.

Why it lives in the tab
ICO is one of those formats most people never need to think about — until they need to extract the icon out of one. Favicons, app icons, legacy Windows resources — all wrapped in this multi-resolution container that few image editors handle gracefully. We crack it open in the browser, pick the largest layer, and write it back out as a clean PNG with alpha intact. Local-first by design.
Frequently asked
What's actually inside an ICO file?
An ICO is a bundle of small bitmap images at different resolutions (16×16, 32×32, 48×48, sometimes 256×256). Windows picks whichever size it needs at the moment.
Which size do you extract?
The largest one available. If the ICO has a 256× layer, that's what you get. Otherwise the next-biggest.
Does the transparency carry over?
Yes — modern ICOs use PNG-encoded layers with full alpha, and the alpha channel ports cleanly to the output PNG.
Can I extract a specific size?
Not in this tool. For per-layer control, drop the ICO into the Artboard image editor.
Will the PNG match the ICO pixel-for-pixel?
Yes. ICO → PNG is a lossless operation when the source layer is itself lossless.
