Crop Image to Square
Crop image to square: a 1:1 frame opens over your photo at the biggest size it fits, you slide it to keep what matters, and the download stays full resolution.
Drop an image to make it square
A 1:1 frame opens on your picture, as large as it fits. Drag it to choose what stays. Or press Ctrl + V to paste one straight from your clipboard. PNG, JPG or WebP, up to 25 MB. Edited in your browser, never uploaded.
A square image cropper
that shows you what gets cut.
Making a picture square means choosing which edges to lose. A tall phone photo gives up a strip at the top and bottom, a wide one gives up its sides. The frame shows both before you commit, so the face stays and the lamp post goes.

Drop, slide the square, save
Three steps in this browser tab, no account, 25 MB per image.
- 01
Drop the photo
A JPG, PNG or WebP. The square frame opens over it straight away, as large as it fits.
- 02
Slide it over the subject
Drag the square up, down or sideways to choose which edges go. The dimmed parts are what gets cut.
- 03
Apply and download
Press Apply, then download. The file keeps its format and every pixel inside the square.
Step by step
Crop image to square in four steps
The frame is already square when the photo lands, so most of the work is one decision: which part to keep.
- Drop the photo: Drag it onto the box at the top of this page, pick it from your files, or paste a screenshot with Ctrl+V. A 1:1 frame opens in the middle, as big as the short side allows.
- Choose what stays: Slide the frame. On an upright photo it moves up and down, on a sideways one left and right, because the square already fills the other direction.
- Leave the size for later: A form wants 1080 by 1080? Crop the full square first, then scale it in the image resizer. Typing 1080 into W and H would cut a 1080 pixel window out of the photo instead, which is a zoom, not a smaller copy.
- Apply and download: Press Apply, open the export and download. The format matches what you dropped unless you pick another one.
Want a smaller square than the frame opened at? Drag a corner handle inward. The frame shrinks from both sides at once and never stops being square.

Crop or pad
Make picture square: crop it or pad it?
There are two ways to turn a rectangle into a square, and they are opposites. One removes picture, the other adds nothing.
Cropping cuts the long side down until it matches the short one. Padding keeps the whole picture and fills the gap with bars, usually white, black or a blurred copy of the photo. This tool crops.
| Crop (this page) | Pad with bars | |
|---|---|---|
| What you lose | The edges of the long side | Nothing, but the photo shrinks inside the square |
| What you gain | A picture that fills the whole square | Every part of the original, including both ends |
| Best for | Portraits, products, anything with one subject | Group photos, panoramas, posters with text at the edges |
Before padding, check whether a square is really required. Plenty of feeds now take a 4:5 portrait, which keeps far more of a tall phone photo than a square does.
Where squares go
Where a square image cropper earns its keep
The square is the shape a small slot can show at any size. That is why the same four places keep asking for one.
- Profile pictures: Most apps take a square and round the corners on screen themselves. Keep the face in the middle, because the corners are what the circle hides.
- Shop listings: A grid of products looks tidy when every thumbnail is the same shape. Crop each one square with a little space around the item.
- Podcast and album art: Cover art has been square since the record sleeve, and YouTube's own help page lists 1:1 as the shape for podcast playlist thumbnails.
- Prints and instant-film looks: Square prints echo the instant camera, whose frame made the shape feel like a finished photo rather than an offcut.

The ratio
Crop image 1:1, and what the numbers mean
A ratio is a shape, not a size. 1:1 says the width equals the height and nothing about how many pixels either one has.
So a 1080 by 1080 image and a 3024 by 3024 one are both 1:1, and so is a 40 pixel avatar. The first number in a ratio is always the width, which is why 4:5 is tall and 16:9 is wide.
The square has a longer history than the phone feed. Medium-format cameras loaded with 120 roll film shot 6x6 negatives for decades, and photographers composed straight into the square rather than trimming to it later.
In the crop toolbar, 1:1 sits next to 4:5, 3:4, 2:3, 3:2, 16:9 and 9:16. Pick another one and the frame refits, centred and as large as the photo allows.

What a square costs
How much of a photo a square keeps
A square can only be as wide as the photo's short side. The longer and thinner the photo, the more of it the square leaves behind.
An ordinary phone photo is 4:3, so a square keeps three quarters of it. A widescreen screenshot keeps barely more than half, which is why a square cut of a slide so often loses its title.
| Picture | Size | Largest 1:1 crop | Share kept |
|---|---|---|---|
| Phone photo, upright | 3024 x 4032 | 3024 x 3024 px | 75% |
| Phone photo, sideways | 4032 x 3024 | 3024 x 3024 px | 75% |
| Camera photo, upright | 4000 x 6000 | 4000 x 4000 px | 66.7% |
| Camera photo, sideways | 6000 x 4000 | 4000 x 4000 px | 66.7% |
| Full HD screenshot | 1920 x 1080 | 1080 x 1080 px | 56.3% |
Those numbers are for the square the frame opens with. Shrink it and you keep less, but a smaller square pulled tight around the subject is often the better photo.
Square crop: common questions
What people ask when a photo has to fit a square slot.
A crop always removes something unless the picture is already square. Keeping all of it means padding the short side with bars, which this tool does not do.
Check the destination first. If it accepts 4:5 or the photo's original shape, cropping to that loses far less than a square.
Any size with equal sides. The biggest square from a 12 megapixel phone photo is 3024 by 3024, because a crop never grows past the photo's short side.
For a set size such as 1080 by 1080, crop the full square, then scale it down in the image resizer with the ratio locked. Nothing extra gets cut that way.
Two typed numbers outrank a ratio, so the lock lets go the moment you type. The frame takes exactly the width and height you entered, in the photo's own pixels.
Type the same number in both fields and it is still a square, just a tighter one. Click 1:1 again to go back to the locked frame.
Upload a square to any site that shows avatars as circles. It rounds the corners itself, and a square gives it the most picture to work with.
Cut a real circle only for places that will not round it for you, like an email signature or a slide.
Yes. The export keeps the format you dropped, so a PNG comes back as a PNG and its see-through areas stay see-through.
Switching to JPG would fill them with white, so leave the format alone unless you want that.
Yes. Pick 4:5, 16:9 or any other ratio in the toolbar and the frame refits to that shape.
It re-centres as it refits, so slide it back over the subject before you press Apply.
