Quick answer
Before uploading a personal photo, check what the service collects, how long it keeps files, whether uploads are used for training, who can access them, and how deletion works. If the answers are unclear, choose a less sensitive image or a different workflow.
Key ideas
- A photo can reveal people, locations, documents, and metadata beyond its main subject.
- Read the service’s current privacy policy and upload terms; do not infer retention or training rules from the interface alone.
- Minimize the image before upload and avoid photos you do not have permission to share.
Treat the whole image as information
A picture may include more than the person or pet you intend to transform. A school badge, address label, computer screen, family photo on a wall, or reflection can disclose details in the background. Original files may also contain location or device metadata, depending on how they were created and exported.
Before uploading, look at the full frame and ask whether every visible detail is needed for the result. Crop unrelated people and documents, remove identifying context when it will not change the drawing, and use a lower-risk sample for testing an unfamiliar service.
Check the service, not just the button
A browser interface does not tell you where processing happens or how long an upload is retained. Read the current privacy notice and terms for the service you are using. Look for the purposes of processing, retention periods, model-training rules, vendor access, security contact, and the method for requesting deletion.
Distinguish “not public” from “not stored” and “not used for training.” Those are separate promises. If a policy says an image is private but also describes temporary storage or abuse review, understand those limits before using photos of children, clients, or other people.
Use a quick pre-upload checklist
Confirm that you own the photo or have permission to use it. Remove details that are not required, especially names, addresses, school information, and visible screens. Avoid uploading medical, identity, financial, or intimate images to a general-purpose tool unless its protections clearly fit that use.
Check whether the service requires an account, what happens to failed jobs, and whether a generated result or source image is saved in a history area. For classroom or client work, follow the organization’s rules and get consent where required. Convenience is not a substitute for permission.
Plan for the image after processing
Decide where you will save the output and who can access it. A converted line drawing can still identify a person if it retains distinctive clothing, a name tag, or a recognizable setting. Removing color does not automatically anonymize an image.
If a service offers deletion controls, learn how to use them before you need them. Keep a copy of the policy version or support route if the image is sensitive. When the policy is vague, ask the provider or use a workflow that keeps the image under your own control.
A practical rule of thumb
Use the least sensitive photo that can still answer the creative question. A clear crop of a pet or object is usually a better test than a family group shot with a recognizable home in the background. You can assess line quality without exposing every detail in the original scene.
For this site, the privacy policy explains how uploaded photos are handled and how to contact us about a deletion request. Review it before using the tool, especially when the image includes someone other than you. The same habit applies to any AI image service.
