About this tool
Cropping is the edit almost every image needs and the one most tools bury inside something larger. Drag the selection over the part you want, pull a corner to resize it, and download. If the crop has to fit somewhere specific, lock it to a ratio first: square for a profile picture or product thumbnail, 16:9 for a video thumbnail or slide, 9:16 for a story or reel, 4:3 and 3:2 for the shapes most cameras and print sizes still use. With a ratio locked the selection keeps its proportions no matter which corner you drag, so you cannot accidentally end up slightly off-square. The crop is taken from the original file at full resolution, not from the preview you see on screen, so a small selection on a large photo stays sharp rather than being scaled up from a downsized copy. PNG files stay PNG by default so transparency survives, and you can convert to JPEG or WebP if you would rather have a smaller file. Nothing is uploaded — the image is read and cropped inside your browser, which matters when the picture is a passport scan or a screenshot of something private.
How to use it
- Drop in a JPEG, PNG or WebP
- Drag the selection, or a corner to resize it — lock an aspect ratio first if the crop has to fit a specific shape
- Crop, then download the result
Frequently asked questions
Does cropping reduce the quality of what is left?
The crop is taken from the original file at full resolution rather than from the preview on screen, so the remaining pixels are the original ones. Exporting as PNG keeps them exactly. Exporting as JPEG or WebP re-compresses, which is why the quality control is there, and 85 is a good default.
How do I crop to an exact square or 16:9?
Pick the ratio before you drag. The selection then keeps those proportions from whichever corner you pull, so the result is exactly square or exactly 16:9 rather than close to it. Switching ratio after selecting keeps the selection centred where it already was.
Can I crop a transparent PNG without losing the transparency?
Yes. Leaving the format on automatic keeps a PNG as a PNG, so transparent areas stay transparent. Converting to JPEG will flatten them onto white, because the JPEG format has no way to store transparency at all.
Why is the crop I get slightly different from what I dragged?
Selections are stored in the image's own pixels and rounded to whole ones, so a selection dragged on a preview that is displayed smaller than the original snaps to the nearest real pixel. On a large photo shown at half size that is a difference of a pixel or two at most.
Is my image uploaded to a server?
No. It is read into your browser and cropped there using your device, so the file never leaves it. That is worth caring about here, because the images people crop are often documents, screenshots or photos they have no intention of sharing whole.
