How it works

Upload your photo

Choose any photo where you want to slim arms. Works best with portraits, selfies, or full-body shots where arms are clearly visible. The AI handles different poses, clothing styles, and lighting conditions automatically.

Expect: Simple uploads: 2-3 seconds. Large files or slow connections: 5-8 seconds.
Describe what you want

Type exactly what you want in plain English—'make the arms slimmer,' 'slim down both arms naturally,' or 'make arms more toned and defined.' The AI understands natural language and applies the change based on your description. Be specific about whether you want subtle slimming or a more noticeable change.

Tip: Add 'naturally' or 'subtly' to your prompt for realistic results that don't look over-edited.

Review the result

Check that the arm slimming looks natural and proportional to the rest of the body. Make sure the AI maintained skin texture, clothing details, and background elements. If it's too subtle or too strong, adjust your prompt and regenerate.
Refine with markers if needed

If the AI slimmed the wrong area or affected both arms when you only wanted one changed, tap a marker on the specific arm you want adjusted. This tells the AI exactly which area to modify when you regenerate.

Tip: Markers are only needed when you want to specify 'this exact arm' or when the photo has multiple people.

"Used this for my professional headshots and the arm slimming looks completely natural. Better than spending hours in Photoshop." @PortraitPro_Sara

If something looks off

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

Why: The AI couldn't determine exactly which area you meant from description alone.

Try: Tap a marker on the specific arm you want to change, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS arm specifically' when there's ambiguity.

The arm slimming looks too extreme or unrealistic

Why: The prompt didn't include guidance for subtle, natural-looking changes.

Try: Add words like 'subtly,' 'naturally,' or 'slightly' to your prompt and regenerate

Try This →

Tip: Specify 'keep proportions realistic' if the AI goes too far with the slimming.

Only one arm changed when I wanted both

Why: The AI may have interpreted your prompt as affecting the most prominent or visible arm.

Try: Change your prompt to explicitly say 'slim both arms' or 'make both arms slimmer'

Try This →

Tip: Always specify 'both' when you want symmetrical changes.

Clothing or accessories look distorted after slimming

Why: The AI slimmed the arm but didn't proportionally adjust sleeves, bracelets, or watches.

Try: Add 'and adjust the sleeves/clothing to fit naturally' to your prompt

Try This →

Tip: Mention specific clothing items in your prompt when they're tight-fitting or detailed.

Skin texture or tattoos got blurred or lost

Why: Aggressive slimming can affect fine details like skin texture, freckles, or tattoos.

Try: Add 'preserve skin texture and details' to your prompt and try a more subtle slimming

Try This →

Tip: For tattooed arms, mention 'keep tattoos intact' in your prompt.

Quick answers

Do I need to mark the arms?

No! Just describe what you want changed—'make the arms slimmer'—and the AI figures out where to apply the change. Markers are only needed if you want to specify one exact arm in a complex photo or group shot.

How do I slim arms in photos for free?

Upload your photo to EditThisPic, type a description like 'make the arms slimmer and more toned,' and click generate. The AI processes it in 5-10 seconds. No signup, no watermark, completely free.

Can I slim just one arm instead of both?

Yes. Specify which arm in your prompt—'slim down only the right arm' or 'make the left arm more toned.' For extra precision, tap a marker on that specific arm before generating.

Will the arm slimming look natural or fake?

The AI maintains realistic proportions and skin texture by default. For the most natural results, include words like 'subtly' or 'naturally' in your prompt. You can always regenerate with a more conservative prompt if the first result is too strong.

Does this work on photos with sleeves or clothing covering the arms?

Yes. The AI can slim arms whether they're bare or covered by clothing. Just mention in your prompt to 'adjust the sleeves to fit' if you want the clothing to adjust proportionally with the slimmed arms.
