Resize & Crop
Crop an Image to Exact Dimensions
Crop to an exact pixel size or a locked aspect ratio. Drag the frame to choose what stays in shot, and watch the output dimensions update as you go.
Getting exactly the dimensions you asked for
Most crop tools give you a rectangle with draggable corners and report the size as you drag. Getting to precisely 1080 by 1080 that way is fiddly on a mouse and close to impossible on a phone, and being one pixel out is exactly the kind of thing an upload validator rejects.
This tool works the other way round. You type the output size you need, the frame locks to that shape, and you move the image behind it. The output is exactly the dimensions you entered because it cannot be anything else — there is no dragging accuracy involved.
Drag to reposition, scroll or pinch to zoom. The rule-of-thirds guides are there to help you place the subject; the frame edge is where the cut happens.
Cropping and resizing are different operations
Cropping cuts pixels away from the edges. What remains keeps its original size and detail. Use it when the image is the wrong shape, or when there is too much empty space around the subject.
Resizing keeps the whole picture but scales every pixel. Use it when the shape is right but the image is too large or too small.
The two are often needed together: crop to the right shape, then scale to the right size. That is what the "scale to these exact dimensions" option does — it crops the framed area and then scales the result to your target. Turn it off if you would rather keep the cropped region at its original pixel density.
If you only need to change the size, the resizer is the simpler tool.
Which aspect ratio for which platform
| Ratio | Common size | Where it is used |
|---|---|---|
| 1:1 | 1080 x 1080 | Instagram squares, marketplace listing photos, avatars |
| 4:5 | 1080 x 1350 | Instagram portrait posts — the most feed space you can occupy |
| 16:9 | 1920 x 1080 | YouTube thumbnails, video, presentation slides |
| 9:16 | 1080 x 1920 | Stories, Reels, TikTok, Shorts |
| 2:3 | 1000 x 1500 | Pinterest pins — taller pins get truncated |
| 3:2 | 1800 x 1200 | Standard photographic print sizes such as 6 x 4 |
Need several of these from one image? The social media sizer produces them all at once.
Cropping and image quality
Cropping itself is lossless — the remaining pixels are untouched. What costs a little quality is saving the result: a JPG has to be re-encoded, which is one more generation of compression. It is a small effect, but it is a reason to crop from your original rather than from a copy that has already been compressed several times.
The bigger risk is cropping too tightly. Cutting a small region out of a small image leaves you with a small image, and enlarging it back up will not restore the detail. Keep an eye on the output dimensions shown below the frame — if the tool warns that the framed area is smaller than your target size, it is about to enlarge and soften your crop.
How to crop an Image to Exact Dimensions
- Drop an image onto the box above.
- Enter the exact output size you need, or choose an aspect ratio such as 1:1 or 16:9 to lock the frame shape.
- Drag the crop frame to position it, and drag its corners to resize.
- Download the cropped image.
Limits worth knowing
Every tool has boundaries. These are this one's, stated plainly so you do not waste time discovering them yourself.
- Cropping removes pixels. If you crop a small area out of a small image, the result will be small — this tool will not upscale it for you unless you ask.
- One image at a time. Batch cropping many different photos to the same frame rarely produces good results, because the subject sits in a different place in each one.
- Cropping a JPG re-encodes it, which costs a little quality. Crop from the original where you can.
