How to Convert ICO to PNG
Add your ICO files
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to PNG
Press Convert. PNG is lossless, so every pixel is preserved exactly.
Download
Save each PNG file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert ICO to PNG?
The main reason is logos, screenshots, text and anything with sharp edges or transparency. ICO excels at favicons and Windows application icons, but when you need pixel-perfect quality, PNG is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
PNG is a lossless format, so the conversion preserves your image exactly — no detail is discarded in the PNG encoding itself.
A note on file size
File size will be broadly similar to your original ICO.

Tips & Things to Know
Check the file size after converting
File size will be broadly similar to your original ICO. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your ICO stay transparent in the PNG — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your ICO files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
The conversion is faithful
PNG is lossless, so every pixel is preserved exactly as it was in your ICO, meaning you do not have to worry about settings — just convert and download.
Frequently Asked Questions
How do I convert ICO to PNG for free?
Add your ICO file above and press Convert. The PNG download appears in seconds. It is completely free, with no signup, no limits and no watermark.
Is my ICO uploaded to a server?
No. The entire conversion runs inside your browser using your device's own processor, so your images never leave your computer. That matters for private photos and confidential work.
Can I convert multiple ICO files at once?
Yes. Add as many as you like and they are converted in one batch, then offered individually or as a single ZIP download.
Will converting to PNG reduce quality?
No. PNG is lossless, so the conversion keeps every pixel. Any quality limit comes only from the original ICO, not from this step.
Does PNG support transparency?
Yes, PNG supports an alpha channel, so transparent areas in your image are preserved.
Why is my PNG file larger than the ICO?
PNG stores up to 16.7 million colours plus an 8-bit alpha channel without lossy compression, so it is naturally larger than ICO. This is expected and the image quality is fully intact.
What is the difference between ICO and PNG?
ICO is the Windows icon and favicon format, holding one or more small square images up to 256×256. PNG is the lossless web standard for graphics, keeping every pixel exact and supporting full transparency. That difference is what this conversion is really about.
Is there a file size limit?
Because processing happens in your browser, very large images depend on your device's memory, but typical photos convert instantly. Nothing is capped by an upload limit.
Do I need to install anything?
No. This works in any modern browser on any device — Windows, Mac, Android or iPhone — with nothing to install.
Is this ICO to PNG converter really free?
Completely free, forever, with no account, no watermark and no hidden premium wall.
