How it works & privacy
How the weight loss preview is made

Review before and after
The AI edits the photo while keeping your face, pose, clothing, and background as close to the original as it can. You can download the result.
Your photo is sent for AI processing.
Your photo is sent through Shelog's server to an AI image service to create the preview and is not stored on Shelog servers. Upload only photos you have the right to use.
How accurate is the result?
The preview is an AI-generated picture. It does not predict how your body would change, how long a change would take, or what your real results would be. Body shape, muscle, genetics, and many other factors affect how weight loss looks on a person.
Results also vary from photo to photo. Clear, well-lit photos where your body is visible usually work best. Face-only photos show changes in the face and neck only.
Does this tell me how much weight I should lose?
No. The tool does not assess your health or recommend a goal. A healthy goal depends on your circumstances, so talk with a qualified professional before setting one.
If you have a history of disordered eating, or if looking at edited images affects how you feel about your body, consider skipping this tool and seeking support from a qualified professional.
What happens to my photo?
Your browser may resize and compress the photo, then sends it to Shelog's server, which passes it to an AI image service to generate the preview. Your photo is not stored on Shelog servers. The AI image service's own data handling and retention policies also apply.
Why did my photo fail or get rejected?
The photo must be a JPEG, PNG, or WebP image. On iPhone, HEIC photos may not be accepted; choose the "Most Compatible" camera format or use Take a Photo. The AI service may also decline some photos. Try a different, clearly lit photo of yourself.
Free use is limited. When the limit is reached, the page will suggest downloading the Shelog app.
