How it works

Upload your photo

Upload any clear photo of a cat — yours, a friend's, or a random cat you found online. Full-body shots work best for maximum chonk effect. Side angles show off the belly the best.

Expect: Upload takes under 5 seconds. Any standard cat photo works — phone photo quality is fine.
Describe how fat the cat should be

Type what you want. The more specific the better — 'extremely chonky with a belly dragging the floor' hits different than just 'fat.' You can specify the face, body shape, leg thickness, and even the vibe (smug, confused, unbothered). The AI handles the rest.

Tip: The word 'chonky' in your prompt consistently produces funnier results than 'fat' or 'obese.' Also try specifying that the cat should look unbothered or smug — it makes the photo 10x funnier.

Loaf cat gone wrong Make this cat look like an enormous loaf — extremely wide and round when sitting, belly spilling out to the sides, tiny head relative to the massive body, same calm loaf expression
Try This →

The overfed look Make this cat look comically overfed — huge round belly like a basketball, slightly confused expression, too chubby to properly sit up straight
Try This →

Side-view belly highlight From this side view, make the cat's belly enormously round and pendulous, dragging close to the ground, rest of the cat proportionally wide and rotund

Tabby goes full chonk

A regular-sized tabby cat photo transformed into a maximum chonk unit. Sent to the owner's family group chat with the caption 'he's been stress eating.'

If something looks off

The cat looks distorted or alien rather than funny-fat

Why: Over-specifying extreme proportions can cause the AI to produce uncanny results where anatomy looks broken rather than chonky.

Try:

Make this cat look realistically chubby and round — like a cat that genuinely weighs 25 pounds, not a cartoon. Keep natural cat proportions but make everything bigger and rounder.

Try This →

Tip: The funniest results are usually the most plausible-looking ones — a cat that could theoretically exist, just extremely rotund.

Only the cat's body changed but the face still looks normal

Why: The AI may prioritize the most prominent feature. If you only described body weight, the face may stay unchanged.

Try:

Make this cat look fat all over — round puffy cheeks, multiple chins, thick neck, heavy round body, chunky legs. Everything proportionally chonky.

Try This →

Tip: Explicitly mentioning face, neck, and legs in your prompt ensures the whole cat gets the chonk treatment.

The background got distorted when the cat changed size

Why: When the AI makes the cat bigger, it sometimes needs to adjust surrounding pixels, which can warp nearby objects.

Try:

Make the cat look much fatter and rounder while keeping the background and surroundings exactly the same. Only change the cat's body shape.

Try This →

Tip: Photos with clear separation between cat and background (solid couch, plain floor) tend to produce cleaner results than cluttered backgrounds.

The result looks more cute than funny

Why: Without specific instructions, the AI defaults to a pleasant result. You need to push it toward comedy.

Try:

Make this cat look EXTREMELY and hilariously fat — comically oversized belly, chubby face, stubby legs straining under the weight, like a cat that has absolutely no regrets

Try This →

Tip: Words like 'comically,' 'hilariously,' and 'absurdly' in your prompt push the AI toward exaggerated results.

The cat fur texture looks wrong after editing

Why: Heavy reshaping of the cat body can sometimes cause the fur pattern or texture to stretch or tile unrealistically.

Try:

Make this cat look fat while keeping the fur pattern and texture natural and realistic — the coat should look smooth and normal, just on a much larger frame

Try This →

Tip: Solid-color cats (black, white, orange) tend to produce cleaner results than heavily patterned cats like tabbies, since there is no pattern to distort.

Quick answers

Do I need to mark the cat in my photo before describing what I want?

No. Just describe what you want in plain text — 'make this cat look extremely fat and chonky' — and the AI finds the cat and reshapes 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 result look convincing enough to fool someone?

At phone screen size, a well-done chonky cat edit is convincing enough to make someone do a double-take before they realize it. The best results come from photos with good lighting and a clear background. Full-body side-view shots tend to produce the most believable and funniest results.

Can I do this with someone else's cat?

Yes. Upload any photo of any cat. You can grab a photo from your friend's Instagram, fatten up their cat, and send it back to them as a completely unprompted bit. Works especially well as a reply to a cat photo someone just shared.

What kind of cat photo works best?

Full-body shots in good lighting work best — especially side views that show the belly clearly. Cats in loaf position or sitting up give the AI the most body to work with. Close-up face shots also work well if you just want the classic chonky face look.

Does EditThisPic store my photos?

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

How is this different from filter apps that just squish or stretch photos?

Apps that stretch or distort photos produce obviously fake results that look like warped reflections. EditThisPic uses AI to understand the cat's anatomy and reshape it in a way that looks like the cat genuinely weighs that much — fur, proportions, and all. The result is funny because it looks plausible, not because it looks like a funhouse mirror.

Can I make the cat look just a little chubby, or does it have to be extreme?

You control the level of chonk. Describe 'slightly pudgy, like a cat that has been eating a bit too much' for a subtle effect, or 'absolutely enormous, maximum chonk, belly dragging the floor' for full absurdity. The AI follows your description.

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.
