How do I convert a PPM file to ICO?

Upload your PPM file, select icon sizes like 16, 32, 48, or 256 pixels, choose whether to preserve aspect ratio, and click Convert. The ICO file will be generated instantly with multiple resolutions embedded.

Why convert PPM to ICO instead of using PPM directly?

PPM is a simple uncompressed format used mainly for image processing pipelines and not supported by browsers or Windows for icons. ICO is the native icon format for Windows, supports multiple sizes in one file and transparent backgrounds, making it ideal for applications and websites.

How does the conversion handle transparency and color depth from PPM to ICO?

PPM stores only RGB without an alpha channel, so transparency cannot be preserved directly. We map the RGB values to a 24-bit or 32-bit ICO array; if the source doesn't include alpha, the icon will have an opaque background. For transparent icons, use a PAM or pre-process your image to add an alpha channel before uploading.
