Crop a photo to any ratio without cutting a head off. Pick the shape of the box you need — square for a profile picture, 16:9 for a thumbnail, 9:16 for a story — and this page proposes where on the image that box should sit. It looks for faces, works out roughly where the person is, and places the crop so nobody is sliced through the forehead. Everything happens inside your browser.
The suggestion arrives as a dashed rectangle drawn over your picture. Your own crop box stays exactly where you left it. Press Use this crop and it moves; press Ignore and it does not. That is the whole interaction, and it is deliberate: an editor that quietly reframes your photo the moment you change a ratio is an editor you have to fight.
Already know where the box goes? The main cropper is the same tool without the suggestion. For an exact pixel size afterwards use crop and resize, and for a round avatar the circle crop or the WhatsApp DP preset is faster.
What you can do here
Faces are the constraint
Face finder (MIT) reports a box and five points per face. A face is kept whole or left out — never cut in half.
The subject, not the centre
Subject mask (Apache-2.0) outlines the person, so a portrait crop clears the head without slicing the shoulders.
Your ratio wins
The suggestion never changes the ratio, preset or shape you picked. It only decides where the box sits and how large it is.
Nothing moves on its own
The proposal is drawn dashed and waits. Accept it, nudge it afterwards with the arrow keys, or ignore it entirely.
No download needed
Without the models, the suggestion is worked out from picture detail on your processor. Every manual control works either way.
Downloaded once
6.1 MB of weights from cdn.pictureeditor.com, cached in your browser, deletable from the panel in one press.
Change the ratio, re-suggest free
The photo is analysed once. Switching from 1:1 to 16:9 re-proposes instantly with no second download and no second inference.
Still just cropping
No enlarging, no filters, no background removal. This page proposes a rectangle; the rest of the site cuts it out.
How to ai smart crop
- 1Open the photo
Drop a JPG, PNG or WebP on the viewfinder. It is read by your browser and goes nowhere else.
- 2Pick the ratio you need
Use the ratio chips or a platform preset. The suggestion will honour whichever you choose.
- 3Press Suggest a crop
Under More options → Smart crop. The first press downloads 19.4 MB once; after that it is instant.
- 4Accept, nudge or ignore
Check the dashed box. Use this crop to accept it, the arrow keys to fine-tune afterwards, or Ignore to leave your own crop alone.
Questions about cropping
What does the smart crop actually do?
You pick the ratio — 1:1, 4:5, 16:9, a platform preset, anything. It proposes where that box should sit: on the subject, with the faces it finds kept whole and a little room above the head. It is drawn as a dashed rectangle. Your crop box does not move until you press Use this crop.
Is my photo uploaded to work out the crop?
No, and it is worth being precise about which way the traffic goes. Two small model files come down to your browser the first time you ask for a suggestion; the photograph goes nowhere. The face finder and the subject mask then run on your own processor against pixels that are already in this tab, and that is equally true if you decline the download.
How big is the download, and where does it come from?
The face finder is 229,738 bytes and the subject mask is 6,163,938 bytes, both fetched once from cdn.pictureeditor.com. The WebAssembly runtime that executes them is served from this site. 19.4 MB the first time, cached after that, and you can delete it from the panel whenever you like.
Can I use it without downloading anything?
Yes. Press No download and the suggestion is worked out from picture detail alone, on your processor, with nothing fetched. It has no idea where a face is, so it is a starting point rather than a guarantee — check the box before you export.
Will it ever cut someone's head off?
Not deliberately: a face it has found is either wholly inside the box or wholly outside it, never halved, and where a ratio cannot hold everybody the largest faces are kept whole and the rest are left out. It finds most faces in a clear photograph, but it does miss some — a profile, deep shade, a very small face in a group — so look at the dashed box before accepting it.
Does it work on photos with no people in them?
It falls back. The subject mask outlines people and nothing else, so on a photo of a building or a plate of food it finds nobody and the suggestion follows where the picture detail is instead. That is usually sensible and occasionally wrong, which is why it is a suggestion.
Can I change the suggestion?
It is an ordinary crop once you accept it: drag it, pull a handle, or nudge it a pixel at a time with the arrow keys. Undo puts it back. And if you would rather it had not suggested anything, press Ignore and nothing happens at all.
Does it resize or enlarge the photo?
No. It only proposes where the crop box goes. Output size, format and file size stay under your control on Crop & Resize, and nothing here enlarges a picture beyond its original pixels.
