Three jobs share one workspace. ID photo crops a selfie to a government specification, measuring head height from the crown rather than estimating it from a facial landmark, then re-checks the finished image and shows you a pass or fail on each rule before you download. Compress brings a photo under an exact file size in kilobytes without changing its dimensions, which is what upload limits usually demand. Signature cleans up a photographed or scanned signature, lifting it off the paper background.
Face detection, background removal, cropping and compression all run as WebAssembly and Canvas code inside this browser tab. Your photo is never transmitted, because there is no server here to receive it — which is also why there is no account to create. Closing the tab discards everything. Details are in the Privacy Policy.
