Tone arms make the arms look more toned and slightly slimmer 30s
Longer legs make the legs look slightly longer and leaner, keep torso and face unchanged 35s

How it works

  1. Upload your photo

    Upload a full-body or three-quarter portrait. Photos where the full figure is visible work best. Good lighting and a contrasting background help the AI distinguish the body outline cleanly. JPG, PNG, and WebP up to 7MB.

    Expect: Subtle proportions adjustments: 25-35 seconds. More complex reshaping with multiple areas: 40-50 seconds.

  2. Describe the shape change you want

    Type what you're going for: 'slim the waist by about 20% while keeping everything else natural' or 'make the legs look slightly longer and leaner, keep the upper body the same.' Be specific about which areas to change and how much. You don't need to mark anything — the AI understands body part names like waist, arms, legs, hips, and shoulders.

    Tip: Use relative terms like 'slightly,' 'subtly,' or 'by about 20%' — they produce more realistic, natural-looking edits than 'dramatically' or 'a lot.'

    Copy one of these to get started:

    Slim the waist slim the waist slightly, about 15-20%, keep the rest of the body and background natural and unwarped

    Tone arms make the arms look more toned and slightly slimmer while keeping the same pose and clothing natural

  3. Check the result looks natural

    Look at the background and clothing edges first — those reveal any warping. The body outline should look smooth and clothes should drape naturally. Zoom in on the waist and arms specifically if those were the target areas.

  4. Use markers for regional precision

    If one specific area looks off while the rest looks good, tap a marker on that spot and add a note like 'just fix the left arm — slim it slightly to match the right.' Markers let you target one part of the body without re-running the full edit.

    Tip: Most body edits work great from description alone. Markers are only for precision touch-ups on specific spots.

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI interpreted the body change more broadly than you intended, affecting areas you wanted untouched.

Try: Tap a marker on the specific body area you want reshaped, then add 'only change the marked area, leave everything else completely unchanged'
Try This →

Tip: Markers combined with 'only the marked area' are the most precise way to target one body part.

Background is warped or wavy after editing

Why: Body reshaping can pull surrounding pixels if the AI doesn't properly separate subject from background.

Try: slim the waist slightly — IMPORTANT: do not warp the background wall or floor, only change the body shape itself
Try This →

Tip: Explicitly saying 'do not warp the background' in your prompt gives the AI a clear constraint that prevents this artifact.

Clothing looks distorted or unnaturally stretched

Why: Fabric patterns and textures are difficult to reshape without visible artifacts, especially with stripes or logos.

Try: reshape the body while maintaining natural clothing texture and pattern — don't stretch or distort the fabric
Try This →

Tip: Solid-colored clothing reshapes cleanest. Striped or patterned clothing may need a second pass or slight marker guidance.

The change is too extreme and looks fake

Why: The AI interpreted 'slim' or 'tone' more aggressively than you wanted.

Try: make a very subtle, natural-looking adjustment — about 5-10% change only, it should look like the same person just at their best
Try This →

Tip: The most convincing body edits are ones no one can tell were made. Start subtle and re-run if you want more.

Face looks different after body editing

Why: The AI inadvertently affected the face region while reshaping nearby areas like neck or shoulders.

Try: reshape the body as described — IMPORTANT: do not change the face, neck, or hair at all
Try This →

Tip: Explicitly protecting the face in your prompt is the easiest way to prevent this common side effect.

Quick answers

Do I need to mark my body outline before editing my shape?

No. Just describe what you want: 'slim the waist slightly, keep everything else natural.' The AI understands body part names like waist, hips, arms, legs, and shoulders without any marking. Only use markers when you want to isolate a very specific small area.

How do I edit my body shape in a photo for free?

Upload your photo to EditThisPic and describe the change: 'slim the waist by about 15%, keep the background and face natural.' The AI reshapes your body proportions in about 30 seconds. Free, no account or login required, no watermark on the result.

Is there a free body shape editor that doesn't require login?

Yes. EditThisPic edits body proportions with AI — no account required, no watermark, and no app to download. Works in any browser on desktop or mobile.

Will the background get distorted when I edit my body shape?

Not if you mention it in your prompt. Include 'do not warp or change the background' in your instruction and the AI will focus only on the body while leaving the wall, floor, and surroundings intact. Photos with a clean, contrasting background also help.

What body proportions can I edit?

Waist, hips, arms, legs, thighs, shoulders, and overall figure. You can slim, broaden, lengthen, shorten, or add toned definition to any of these areas. The more specific your description, the more targeted the result.

How do I make my body edit look natural and not fake?

Use subtle percentages: 'slim by about 10-15%' rather than 'slim dramatically.' Mention preserving clothing texture and not warping the background. The most convincing edits are the ones that look like the natural you.
