Advanced ICO to PNG Converter

ICO (Icon) is a Windows-specific format that can contain multiple images at different sizes in a single file, typically used for application icons. PNG (Portable Network Graphics) is a universal raster image format that supports transparency and lossless compression, widely used for web graphics.

There’s no hard limit to the number of files, but performance may be affected if you try to convert a very large number of files simultaneously (typically more than 20-30 at once). For best results, we recommend converting files in batches of 10-15 at a time.

Yes, transparency in ICO files is preserved during conversion to PNG. The tool maintains the alpha channel, so transparent areas in your original icon will remain transparent in the output PNG file.

No, this tool currently only converts from ICO to PNG format. Converting PNG to ICO requires different processing as ICO files can contain multiple image sizes and have specific format requirements for Windows icons.

Common reasons include: using Windows icons on non-Windows platforms, embedding icons in documentation or websites, editing icons in image editors that don’t support ICO format, or when you need a single-size image rather than the multi-size format of ICO files.
