How do I convert an ICO file to PPM?

Upload your ICO file, choose the specific icon size/depth (e.g., 256x256, 32-bit) if multiple are present, set output options if any, then click Convert. The tool extracts the selected raster image and writes an uncompressed PPM (P6) file containing raw RGB pixel data, ready for download.

Why would I want to convert an ICO to PPM?

PPM is a simple, uncompressed format used in image processing, scientific visualization, and legacy Unix tools. Unlike ICO, which is a Windows icon container with multiple sizes and optional transparency, PPM provides direct RGB data that is easy to parse in scripts, compiled programs, or applications like Netpbm and MATLAB, offering pixel-exact output without compression artifacts.

How does the conversion handle transparency, multiple sizes, and color profiles?

ICO can bundle multiple resolutions and an alpha channel. Since PPM does not support alpha natively, transparency is either discarded or optionally composited on a chosen background color. If the ICO contains multiple sizes, the tool lets you pick one. Color profiles are not preserved because PPM stores only raw RGB values, so the converter outputs the exact RGB numbers from the source without gamma or profile-based adjustments.
