Reshape Waist & Body in Your Photo
Upload a photo, adjust the effect in real time, and download the result. A small AI model helps locate the torso while the selected image stays in your browser.

How it works
AI positions the focus. WebGL reshapes the pixels.
A lightweight pose model estimates shoulder and hip landmarks, which helps place the waist focus. The actual visual transformation is a real-time WebGL pixel warp rather than a large generative image model.
2
Detect the torso
Pose Landmarker estimates the body focus. If detection is unclear, simply tap the photo to place the focus yourself.
3
Adjust & download
Fine-tune strength, effect area and blend, compare with the original, then save the finished image as a PNG.
Processed on-device
The selected image is not sent to a Siamese Cat server by this tool. The MediaPipe runtime and model are downloaded to the browser and inference happens on the user's device.
Live adjustments
WebGL handles the visual warp, so slider changes are rendered immediately without waiting for a server-side processing queue.
AI is optional
If AI detection is unavailable or turned off, the user can tap the image to place the reshape focus manually and continue editing.

FAQ
Questions about the online skinny filter
Does this tool upload my photo to a server?
No. The tool reads and edits the selected image in your browser. It does not send that photo to a Siamese Cat server. The page does download the MediaPipe runtime and AI model from a CDN/Google Storage so the AI can run on the device.
Does the skinny filter use AI?
Yes, but only a small pose-detection model to identify useful body landmarks such as the shoulders and hips. The actual reshape is a WebGL pixel warp, not a large generative image model.
Why can the background look bent?
This type of reshape moves pixels around the torso. Strong settings can affect nearby straight background lines. Lower the strength or effect area for a more natural result.
Does it work on phones?
It is designed for modern browsers with JavaScript and WebGL. AI speed depends on the device and browser. If AI detection cannot load, the manual focus mode still works.
Can this filter measure body weight or health?
No. It only changes the appearance of a photo for creative editing. It does not measure weight, health, body composition, or a person's real-world proportions.
Responsible use
Keep editing private and consensual
Use photos you own or have permission to edit. This is an adult portrait editor: do not use it on children’s photos. Your selected image stays in your browser; optional pose detection is processed on your device.
