Limitations

Very large images can hit the device's memory limit, and output quality depends on the browser's canvas encoder.

Privacy and accuracy

Favicon Generator processes its input in the browser whenever the platform API allows it. Files and values are not uploaded to a server for processing, and the tool does not require an account.
