This PNG converter runs entirely in your browser. When you drop a file, it stays on your device—we never upload it to our servers, store a copy, or open it on our side. We cannot see what is inside your PNG, and refreshing or closing the page clears everything from memory instantly. No account is required to convert.
Note: like most websites, we may use cookies for ads and analytics on public pages. That is separate from your document—those scripts never receive your file contents.
