Square PNG with transparent background works best

Upload an image to build a real multi-resolution .ico file — 16, 32, 48, 64, 128, 256px in one file

Unlike tools that just rename a single PNG to .ico, DCPIXEL builds a genuine multi-resolution icon file containing 16, 32, 48, 64, 128, and 256px versions in one .ico container — exactly what Windows and desktop apps expect.

자주 묻는 질문 (FAQ)

Why not just rename a PNG to .ico?
A renamed PNG is not a valid .ico file — Windows and many apps expect the real ICO container format with multiple embedded resolutions, which is exactly what this tool builds.
Which sizes are included?
16, 32, 48, 64, 128, and 256 pixels, all packed into a single .ico file so the right size is used automatically wherever it's needed.
What is the best source image to use?
A square image, ideally 256×256px or larger, with a transparent background for the cleanest result at every size.
