how to convert ico to png
Drop your ICO file
Drag your ICO file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs Canvas API on your device to decode the Windows Icon and encode it as Portable Network Graphics. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the PNG file
When the conversion finishes, the PNG file is ready to download. Save it anywhere on your device.
FAQ
common questions
Will my ICO file lose quality when converted to PNG?
Quality is preserved at the data level — the converter unpacks Windows Icon and re-stores the same content as Portable Network Graphics. Any quality differences come from the encoders inside each container, not from the conversion itself.
What happens to transparency when converting ICO to PNG?
Yes. Both Windows Icon and Portable Network Graphics support transparency, so any alpha channel in your source ICO is preserved in the PNG output.
Will the PNG file be smaller or larger than my ICO?
Usually much larger — sometimes 2–10× the size of the source. Portable Network Graphics is a less compressed format than Windows Icon; the trade-off is editability or compatibility rather than file size.
When does it make sense to convert ICO to PNG?
Common reasons: ICO is only practical for icons — not a general image format, while PNG is lossless — saving and re-saving never degrades quality. Converting also matters when the app, device, or platform you're sharing with prefers Portable Network Graphics — every image viewer, browser, and graphics tool.
Where will my PNG file open after conversion?
Every image viewer, browser, and graphics tool. Portable Network Graphics is widely enough supported that you can hand the output file to most modern apps and expect them to render it.
Does this site upload my ICO files anywhere?
No. The whole conversion runs in your browser using Canvas API. The file you drop in never leaves your device — we don't see it, and we couldn't even if we wanted to.
Is there a file size limit for ICO to PNG?
There's no hard cap — limit is your device's memory. Several hundred megabytes works fine on a typical laptop. Phones and low-RAM machines may struggle with very large files.
Does ICO to PNG work offline?
Once this page has loaded, yes. The converter library lives in your browser and runs without any further network calls. Reloading the page does still need connectivity.
