How it works

  1. Upload your photo

    Upload a photo of the person you want to slim. Full-body photos work best for body slimming, while portraits are better for just slimming the face. The whole body or area you want to reshape should be in frame.

    Expect: Upload takes a few seconds. Full-body shots in good lighting give the best results.

  2. Describe the slimmer version

    Type how much slimmer you want the person to look and which areas to focus on — waist, face, arms, legs, or overall. Be specific about the degree of change. 'Noticeably slimmer' works, but 'slim the waist by about 30%, lean out the arms, and slim the face slightly' gives more control.

    Tip: Specify 'realistic proportions' to avoid an uncanny stretched look. Also helpful: 'keep the background unchanged' so the wall and floor don't warp alongside the body.

    Copy one of these to get started:

    Noticeable full-body slimming Make this person look noticeably slimmer overall — slim the waist, slim the face, lean out the arms and legs. Realistic proportions, keep the background unchanged, still clearly the same person.

    Dramatic slimming for shock value Make this person look dramatically thin — very slim waist, lean face with prominent cheekbones, slender arms. Much thinner than they currently look. Keep their clothing and background the same.
    Try This →
    Face only — slim face and jawline Slim just the face in this photo — sharper jawline, slimmer cheeks, slightly more defined bone structure. Keep the body and background unchanged.
    Try This →
    Waist only — hourglass effect Slim just the waist and midsection area — make the waist noticeably narrower while keeping shoulders, hips, and face proportional. Natural hourglass effect.

    Subtle slimming — 'lost some weight' Make this person look like they've lost about 15-20 pounds — slightly slimmer face, more defined jawline, slightly less bulk in the torso. Subtle and realistic, not dramatic.
    Try This →
    Extreme — impossibly skinny Make this person look cartoon-level thin — extremely narrow waist, stick-thin arms, gaunt face. Exaggerated and clearly satirical, not meant to look realistic.

  3. Send it

    Download and send. Best prank angle: 'guess who started their diet' or just drop the photo with no caption. If you're using it for yourself as fitness motivation, this is your before-and-after preview.

Full-body slimming prank

Full-body photo slimmed overall — narrower waist, leaner arms, slimmer face. Sent with 'two weeks of Pilates, feeling good' as a caption.

Face-only slimming for subtle prank

Portrait with only the face slimmed — sharper jawline, less full cheeks. Used as a 'got a haircut' photo to see if people would notice the actual difference.

Prompt: Slim just the face in this photo — sharper jawline, slimmer cheeks, slightly more defined bone structure. Keep the body and background unchanged.

If something looks off

The background warped or stretched alongside the person

Why: The AI reshaped the body without explicitly keeping the background fixed, causing the surrounding area to distort.

Try: Slim the person's body only — keep the background, floor, walls, and all objects in the background completely unchanged and undistorted.
Try This →

Tip: Photos with a simple solid-color or blurred background are the easiest to slim convincingly. Busy backgrounds with strong straight lines (like tiled floors) make distortion more visible.

The proportions look wrong — head too big for the body

Why: Heavy body slimming without adjusting the head can make the proportions look unnatural.

Try: Slim the body and face together proportionally — slim the face slightly and the body more, so everything stays in realistic proportion.
Try This →

Tip: Always include some face slimming alongside body slimming to maintain natural proportions.

The clothing looks stretched or wrinkled in odd ways

Why: When the body is reshaped, clothing that fits snugly can show distortion artifacts.

Try: Slim the body and make sure the clothing fits naturally on the slimmer frame — no stretching, bunching, or unnatural fabric distortion.
Try This →

Tip: Loose-fitting clothing (like a t-shirt or a jacket) slims more cleanly than tight-fitting clothes. Avoid using very form-fitting outfits in photos you're planning to slim.

The slimming looks obviously edited — uncanny

Why: Aggressive slimming on photos with shadows or complex lighting can create visible artifacts.

Try: Apply realistic, natural-looking slimming — the result should look like a real photograph of a naturally slimmer person, not an obviously edited image.
Try This →

Tip: Reduce the amount of slimming you're asking for. 'Noticeably slimmer' works better than 'dramatically slim.' More subtle = more convincing.

Quick answers

Do I need to select or mark the body area before asking for the slim edit?

No. Just describe what you want slimmed and how much — 'slim the waist and face, realistic proportions' — and the AI applies it.

Is this free?

Yes. EditThisPic gives you 1 free edit per week with no account needed. For more edits, credits start at $1.99. No subscription required.

Will the slimmed version look realistic enough to fool someone?

For a subtle 'noticeably thinner' result, yes — especially at phone screen size. The AI produces realistic proportions when you ask for 'natural' or 'realistic' slimming. Dramatic or extreme slimming will look more obviously edited. For prank purposes, subtle is usually more effective.

Can I slim just one area, like the waist only?

Yes. Describe specifically which area you want to slim — 'just the waist,' 'only the face,' 'arms and legs only.' The AI follows your description and targets the areas you specify.

Does this work on full-body photos and portraits?

Both work. Full-body photos are better for whole-body slimming. Portraits are better for face slimming specifically. The more visible the area you want to change, the better the result.

Can I apply the slimming edit to someone else's photo?

Yes. Upload any photo of any person and describe the slimming effect you want. It works on photos of friends, family, or anyone.

Does EditThisPic store my photos?

Photos are processed to generate your edit and not stored beyond the session. No account means no personal data is collected by default.

How is this different from Photoshop liquify or other body editing apps?

Photoshop's liquify tool manually warps pixels — you drag areas around, which often creates visible distortion in the background or clothing. EditThisPic uses AI that understands the full image and makes proportional adjustments, keeping the background intact and the clothing natural-looking.

How much does EditThisPic cost?

You get 1 free edit per week — no account needed. After that, credit packs start at $1.99 for 3 edits. Monthly plans start at $4.99/mo for 15 edits with unused credits rolling over. All edits are full resolution with no watermark.
