How it works

  1. Upload your photo

    Choose a photo where your arms are clearly visible. Photos with good lighting and your arms not crossed or behind objects work best. The AI can work with selfies, group photos, or professional shots.

    Expect: Simple edits: 15-20 seconds. Complex lighting or poses: 30-45 seconds and may need refinements.
  2. Describe what you want

    Type your instruction like 'make my arms look slimmer' or 'tone my arms to look more defined.' No need to mark anything first - just describe the change you want. Be specific about whether you want subtle slimming, more definition, or both.

    Tip: Mention 'natural' or 'realistic' in your prompt if you want subtle changes that don't look over-edited

    Copy one of these to get started:

    Basic arm slimming Make my arms look slimmer and more toned
    Natural fitness look Slim my arms to look naturally toned like I work out regularly
    Subtle enhancement Make my arms appear slightly slimmer and more defined without looking edited
    Wedding/formal photos Slim and tone my arms for a more elegant appearance in this formal photo
    3 more prompts
    One arm focus Make my left arm look slimmer and more toned while keeping the right arm unchanged
    Muscle definition Add muscle definition to my arms to show more visible tone and strength
    Proportional adjustment Adjust my arm size to be more proportional to my body frame
  3. Review the result

    Check that your arms look naturally slimmed without affecting other body parts. Zoom in to ensure the editing looks realistic around the arm area and clothing still fits naturally.
