How it works

  1. Upload your cat's photo

    Drop a photo of any cat into EditThisPic. Full body shots where you can see the whole cat work best, but even sitting or loaf-position cats produce hilarious results. JPG, PNG, or WebP up to 7MB.

    Expect: Most edits complete in 20-45 seconds. The AI works with every cat breed and color.
  2. Describe the chonk level

    Type how fat you want your cat to look. 'Make this cat look extremely round and overweight' is a great start. Get creative β€” the more specific, the funnier the result.

    Tip: Cats have iconic fat poses β€” try 'make this cat look like a perfectly round loaf that takes up the entire couch' or 'so fat their legs don't touch the ground when they sit.' Cat-specific language makes the AI nail it.

    Copy one of these to get started:

    Classic chonker Make this cat look like the fattest cat on the internet β€” perfectly round body, belly dragging on the ground, little fat paws, but keep that adorable face exactly the same.
    Orange cat energy Make this cat look massively overweight like the stereotypical orange cat that has one brain cell and zero self-control around food. Round as a basketball, pure chonk energy.
    Cat loaf supreme Make this cat look like the world's biggest cat loaf β€” so round and fat that in loaf position they're basically a sphere. No visible legs, just a massive fluffy blob with a face.
    Cat-sitting prank Make this cat look like they've gained 15 pounds in a week. Realistic enough to worry the owner β€” noticeably bigger belly, thicker body, heavier-looking. Keep it believable.
    4 more prompts
    Fluffy to mega-fluffy Make this fluffy cat look three times wider β€” like they have 50 pounds of extra floof and fat combined. An enormous cloud of fur with a tiny face peeking out.
    Pancake cat Make this cat look so fat they've melted into a flat puddle shape β€” wide and low to the ground, spreading out in every direction like a furry pancake with eyes.
    Tuxedo chonk Make this tuxedo cat look enormously fat, like they're wearing a tuxedo that's 5 sizes too small. The black and white markings should stretch across a massive round body.
    Royal chonk Make this cat look like a spoiled royal cat who's been hand-fed tuna and cream for years β€” enormously plump, regal expression, massive belly, sitting like they own the place.
  3. Share your chonker

    Download the result and send it to the cat's owner, your group chat, or social media. No watermark. Caption suggestion: 'Your cat has been eating VERY well.'

Tabby to chonker

A normal tabby cat transformed into a magnificently round chonker.

Prompt: Make this cat look like the fattest cat on the internet β€” perfectly round body, belly dragging on the ground.
Orange tabby cat at normal weight
Before
->
Same orange cat made to look hilariously overweight
After

Orange cat maximum chonk

An orange cat living up to the one-brain-cell stereotype, now in maximum chonk form.

Prompt: Make this cat look massively overweight like the stereotypical orange cat with zero self-control around food.

If something looks off

The cat's face changed too much

Why: The AI modified facial features along with the body.

Try: Make only the cat's body look fat β€” keep the face, ears, whiskers, and eye color exactly the same

Tip: Include 'keep the face identical' in any prank photo prompt β€” the owner needs to recognize their cat.

The cat looks stretched instead of fat

Why: The AI warped the image rather than adding natural-looking weight.

Try: Add realistic fat and roundness to this cat's body β€” wide round belly, thick legs, fat cheeks β€” without stretching or distorting

Tip: Words like 'round,' 'plump,' and 'chubby' produce better results than 'fat' alone.

Cat doesn't look fat enough

Why: The prompt didn't push the transformation far enough.

Try: Make this cat look EXTREMELY overweight β€” at least triple the body size, enormous belly, barely able to see their paws under all the fat

Tip: Exaggerate: 'triple the body size,' 'enormous,' 'barely able to walk' signal the AI to go all-in.

The fur pattern disappeared or looks weird

Why: The AI lost the coat pattern while adding weight.

Try: Make this cat look very fat but preserve the exact fur color pattern and markings across the larger body

Tip: Mention the specific coat pattern ('keep the tabby stripes' or 'maintain the tuxedo markings') for best results.

Quick answers

Do I need to mark the cat in the photo?

No. Just upload and describe β€” the AI finds the cat automatically. Only use markers if there are multiple cats and you want to fatten a specific one.

Is this completely free?

Yes β€” 1 free edit per week, no account needed. For unlimited chonky cat edits, plans start at $1.99.

Does it work with all cat breeds?

Yes. Tabbies, Persians, Siamese, Maine Coons, orange cats, black cats, calicos, tuxedos β€” every breed and color works. Each produces hilariously different results.

Will the cat still look like themselves?

Yes β€” the AI preserves the face, markings, eye color, and personality. The body gets chonky but the cat is still 100% recognizable, which is what makes it work as a prank.

What photo angle works best?

Full body shots β€” standing, sitting, or loafing β€” give the best results. The AI needs to see enough of the body to convincingly add weight. Close-up face shots will only add chubby cheeks.

Can I use this on my phone?

Yes. EditThisPic works in any mobile browser β€” iPhone, Android, tablet. No app needed. Snap a photo of the cat and edit it immediately.

Is there a watermark?

No watermark on any download. The image looks completely natural β€” nothing reveals it was AI-edited.

How much does EditThisPic cost?

You get 1 free edit per week β€” 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.
