It depends entirely on where you set the slider! If you keep the slider at 85%, the file size drops significantly with almost no visible loss of clarity. If you push the slider to 100%, the image is saved using a "lossless" algorithm, meaning it stays mathematically perfect.
It is perfectly safe because nothing is actually uploaded to our servers! This tool leverages modern HTML5 Canvas technology to read and convert the icon entirely inside your own web browser. Your files never leave your device.
