Every size stored inside is unpacked as its own transparent PNG.
Download individual sizes or all as a ZIP.

Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Unpacking the container
A .ico is not one image — it is a box holding the same icon at several sizes, each hand-tuned (a good 16-pixel
favicon is drawn, not scaled). Converting "ICO to PNG" properly means unpacking all of them at their true pixels,
which is exactly what happens here, transparency intact.
Useful for recovering an icon whose source file is long gone, reusing a favicon in documentation, or editing a
legacy Windows icon in a normal editor. The reverse trip — building a proper multi-size .ico — is
PNG to ICO, and the full favicon package is the
Favicon Generator.
Frequently asked questions
Why does one ICO give several PNGs?
An ICO is a container holding the same icon at several sizes (16, 32, 48…). This tool unpacks all of them, so you get each size at its true pixels instead of one scaled guess.
What is this for?
Reusing a site’s icon in documentation or bookmarks managers, recovering an icon whose source is lost, or editing a legacy .ico in a normal image editor. The reverse direction is PNG to ICO.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
