About PNG and ICO
image/png
PNG is a raster-graphics file-format that supports lossless data compression. It supports palette-based images, grayscale, and full-color non-palette-based RGB or RGBA images. Its most notable feature is support for transparency (alpha channel).
image/vnd.microsoft.icon
Image file format used for icons in Microsoft Windows. It can contain multiple images at different sizes and color depths.
Conversion Notes
Image conversion from PNG to ICO preserves colour information and dimensions. If ICO uses lossy compression (such as JPEG), compression artefacts appear at lower quality settings — use quality 85+ to minimise visible loss. Transparency (alpha channel) is preserved in formats that support it; if the target format does not support transparency, transparent areas are filled with white by default.
