Crop an image
Square, portrait or widescreen — in your browser, never uploaded.
How it works
Three steps, and nothing leaves your device.
-
1
Drop in the image
The whole image is selected to start with, so you can see the full frame.
-
2
Pick an aspect ratio
The largest area of that shape is centred in your image. Choose Original to keep the frame as it is.
-
3
Download the crop
Only the selected area is encoded — the rest is discarded, not hidden.
Which ratio to crop to
- 1:1 square is the safe social default. Square thumbnails are used across marketplaces, profile images and product grids. Because it is symmetrical, a square crop rarely breaks a composition — but it also removes the most from a wide landscape photo, so check that the subject survives.
- 4:5 portrait takes the most vertical space in a feed. On a phone, a 4:5 image occupies noticeably more screen than a square and considerably more than a landscape shot. If a photo is going into a scrolling feed and you want it to be seen, this is the ratio to use.
- 16:9 is for video frames and page headers. It matches screens and video, which makes it right for a hero banner or a thumbnail that sits alongside video content. It is the wrong shape for a person standing up.
- Crop before resizing. Cropping changes which pixels you keep; resizing changes how many. Doing it in that order means you resize only the part you are actually going to use, which gives a sharper result at a given file size.
Frequently asked questions
Can I choose the crop area myself?
The presets centre the largest area of the chosen shape. Choose Original to keep the full frame, then use the resize tool if you need specific dimensions.
Does cropping reduce quality?
No. Cropping selects a region of the existing pixels — the kept area is untouched. The file gets smaller only because there is less of it.
Is the image uploaded?
No. The crop is performed in your browser and the file never leaves your device.
