Stenciltool is a client-side tool. Every step of the conversion — loading your image, grayscale, blur, thresholding, edge detection, and export — runs inside your web browser on your own device. Your images, text, and downloads are never uploaded, transmitted, or stored on our servers. We could not see them even if we wanted to.
The tool requires no registration, login, or email address. We do not collect names, contact details, or any personally identifying information to use the converter.
Pages load web fonts from Google Fonts. When your browser fetches a font file, Google receives a standard web request (IP address, user agent). See Google's privacy policy for how they handle those requests.
This site may display advertising (such as Google AdSense) and use privacy-respecting traffic analytics to keep the tool free. Advertising partners may use cookies or similar technologies to serve and measure ads; where required, you will be shown a consent prompt and can decline personalised advertising. Ad partners never receive the images you convert — those stay in your browser.
Some pages link to craft supplies on Amazon. As an Amazon Associate, this site may earn a commission from qualifying purchases. These links do not affect what you pay and carry no information about your converted images.
