About ICO to PNG Converter
ICO is the Windows icon container format, used mostly for website favicons. PNG is a lossless format with full transparency support, ideal for logos, icons, and screenshots.
Converting ICO to PNG produces a lossless file that opens in virtually every browser, operating system, and image editor. Drop your file above and it is decoded and re-encoded as PNG entirely inside your browser, so even sensitive images never leave your device.
To use it, drop your ICO file into the upload area or click to pick one from disk. The conversion runs as a single pass — the ICO bytes are decoded into a pixel buffer and re-encoded as PNG losslessly, so the output pixels are identical to what the ICO decoded to. Output dimensions match the source; to resize as well, run the image resizer before or after the conversion. A typical photo converts within a second or two on a modern device.
