How PNG to ICO Conversion Works
PNG is an image format: it uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. ICO is an image format that bundles multiple raster images at different resolutions (16x16 through 256x256) into a single file for use as application icons. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. Converting between these two formats is common when the source application does not support ICO natively or when the target platform only accepts ICO. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
