ICO is the Windows icon format. One file holds the same picture in several sizes, each at most 256 × 256 pixels; browsers also use it for the small icon on a tab (the favicon). ICO files can be saved as AVIF, BMP, EPS, GIF, JPG, PDF, PNG, PS, PSD, TIFF, WEBP, and most of these conversions run right in your browser, so your pictures stay on your device.

Are my ICO files uploaded anywhere?
Pictures up to 200 MB never leave your device: ConvertKitty converts them inside your browser, with ImageMagick compiled to WebAssembly. Only larger files, or formats your browser cannot handle (camera RAW, PostScript, XPS, LibreOffice and Publisher files, and video or audio), are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
