Choosing a photo opens a preview in your browser. Only when you press the processing button is a working copy sent through this site to Xiaobei API, our third-party image-processing provider. The provider generates a result, which our server retrieves and returns to your browser. Only use photos you have permission to edit, and avoid uploading sensitive documents or private images you are not comfortable sharing with this provider.
Your most recent original and result can be saved in this browser for up to 24 hours so that refreshing can restore them. Start over removes the saved pair. Expired items are removed the next time you visit. Browser storage may be unavailable, so download a copy you want to keep.
This site does not publish uploaded photos or maintain a public photo gallery. The processing provider and its image-delivery service handle images outside your browser. We do not promise immediate deletion from their systems or a verified retention period. Your network identifier is hashed for usage limits; people sharing a network may share an allowance.
No advertising or analytics service is enabled in this release. Photos, filenames and generated images are not sent to analytics. This page describes the current processing flow; review it again if you return after a service change.
