Privacy
Your files never leave your device. This site has no upload endpoint and no server that could receive one. The image you choose is read by your own browser, processed by your own CPU, and written back to your own disk when you press download. Nothing is transmitted, because there is nowhere for it to be transmitted to.
You do not have to take that on faith. Open your browser's developer tools, switch to the Network tab, and use the tool. You will see the page's own files load and then nothing further — no request carrying your image, because none is ever made.
What is stored
Your last-used settings are kept in your browser's local storage so the tool remembers them next visit. That data sits on your device and is readable only by this site in this browser. Clearing your browser data removes it. There is no account, no login, and no server-side database.
Advertising
This site is funded by Google AdSense. Google and its partners may use cookies or device identifiers to serve and measure ads, including personalised ads where you have consented. Manage your choices at myadcenter.google.com, and see how Google uses data from sites using its services at policies.google.com/technologies/partner-sites. Ad requests are the only network traffic this site generates after load — and they carry no part of your file.
