How it works

Upload your photo

Upload any photo with a person clearly visible. Full-body photos work best for dramatic results; portraits work well for face and upper-body slimming. JPG, PNG, or WebP up to 7MB.

Expect: Most results arrive in 15-30 seconds. Full-body reshaping may take up to 40 seconds.
Describe the slim look

Type what you want: 'make this person look noticeably slimmer' or 'slim down the waist, hips, and face naturally.' Be specific about which areas — the AI can focus on the whole body or just the face, arms, or midsection.

Tip: Phrases like 'naturally slimmer' and 'keep proportions realistic' give the AI clearer direction and prevent the warped-mirror look.

What would I look like 20 pounds lighter

Prompt: make this person look like they lost about 20 pounds — slimmer everywhere but still realistic and proportional

If something looks off

The background or clothes look warped or stretched

Why: The AI reshaped the body but didn't cleanly reconstruct the surroundings — common when someone is near a wall with a strong pattern or wearing fitted clothing with visible lines.

Try: slim down this person naturally, keep the background and clothing pattern exactly the same, only reshape the body

Try This →

Tip: Photos with plain backgrounds and loose-fitting clothing give the AI more room to reshape without distortion.

Result looks like a funhouse mirror — too stretched or unnaturally narrow

Why: The slim instruction was interpreted too literally without a proportionality constraint.

Try: make this person look slimmer but keep proportions completely realistic and natural — no distortion

Try This →

Tip: Always include 'realistic proportions' in your prompt when you want the result to be believable.

Only the face changed but the body stayed the same

Why: The AI focused on the most prominent area (the face) and missed the rest of the body.

Try: slim down the whole body — waist, hips, arms, and legs — not just the face

Try This →

Tip: Listing body parts explicitly ('waist, hips, arms') tells the AI exactly where to apply the edit.

The person's face features changed along with the shape

Why: Slimming the face can inadvertently shift eyes, nose, or mouth positions if the AI over-adjusts.

Try: slim the face shape only — cheeks and jawline — keep the eyes, nose, and mouth position exactly the same

Try This →

Tip: Specifying 'keep facial features in the same position' preserves the person's identity while changing the face shape.

Effect is too subtle — can barely see a difference

Why: The AI defaulted to a conservative change to avoid over-editing.

Try: make this person dramatically and noticeably slimmer — a significant visible difference, not subtle

Try This →

Tip: Words like 'dramatically', 'significantly', and 'obvious difference' signal to the AI that you want a strong effect.

Quick answers

Do I need to mark the body areas before describing what I want?

No. Just type 'make this person look slimmer' and the AI identifies and reshapes the body automatically. Only use markers if the AI changes something you didn't want changed — like the background or another person in the photo.

Is this free?

Yes. EditThisPic gives you 1 free edit per week with no account needed. For more edits, plans start at $4.99/month.

Will this look realistic enough to fool someone?

For moderate changes — like a slimmer face or a 10-20 pound lighter look — the results are convincing enough to make someone do a double-take. Dramatic full-body transformations can look slightly edited but are still good enough for a prank reaction.

Can I use this to see what I'd look like after losing weight?

That's exactly what a lot of people use it for. Upload your photo and type 'make this person look like they lost 20 pounds' or whatever target you have in mind. The AI gives you a realistic preview to visualize the goal.

Can I slim just one part — like only the face or only the waist?

Yes. Be specific in your prompt: 'slim down the face only, keep the body the same' or 'slim the waist and hips, keep the rest unchanged.' The more targeted your description, the more precise the result.

Will this work on group photos?

Yes, but describe which person to slim. 'Make the person on the left look slimmer' or 'slim down the woman in the red dress' helps the AI target the right subject.

Is my photo stored or shared?

No. EditThisPic processes your photo for the edit and does not store or share it. Your images stay private.

What's the difference between this and apps like FaceApp or Facetune?

Apps like FaceApp and Facetune use fixed sliders and preset filters. EditThisPic lets you describe exactly what you want in plain language — 'slim the waist but keep the shoulders broad' — which gives you much more control over the result than a generic slim slider.

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.
