Crop an Image
Draw the frame, keep what matters, discard the rest. Snap to a ratio for profile pictures and thumbnails or crop freehand — the work happens on your own device, and the stamp confirms the exact pixel size you cut.

How it works
Cropping is a straight copy of pixels: the area inside your frame is transferred to the output untouched — nothing is resampled, so there is no quality change inside the kept region. Choosing a ratio locks the frame’s shape while you drag, which is how you hit a platform’s spec (square avatar, 16:9 thumbnail) without arithmetic. The output keeps your original format: a JPG crops to JPG, and a PNG crops to PNG with any transparency in the kept area preserved. The readout under the picture shows the crop’s live pixel dimensions, and after cropping the stamp records the final size.

Frequently asked questions
How do I crop an image without losing quality?
Crop here. A crop copies the selected pixels as they are — no scaling, no resampling — so the kept area is identical to the original. Only saving in a lossy format re-encodes, and for a JPG source that single re-encode at high quality is not visible.
How do I crop to a square for a profile picture?
Choose Square 1:1 from the ratio menu. The frame stays square however you drag it, so whatever you select is guaranteed to fit avatar slots without stretching. For a circular avatar with transparent corners, use our Crop Image into a Circle tool instead.
Can I crop to exact pixel dimensions?
The live readout under the image shows the frame’s width and height in real pixels as you drag, so you can stop exactly on the numbers you need. If you need a specific final size like 1280×720 regardless of the source, crop to 16:9 here, then run the result through Resize to Exact Pixels.
What does the aspect ratio menu actually do?
It locks the frame’s shape. 1:1 keeps it square, 16:9 keeps it widescreen, and so on — you still choose the position and how much of the image to keep. Free removes the lock entirely.
Does cropping remove parts of the file or just hide them?
It removes them. The output contains only the pixels inside your frame; everything outside is gone from the saved file. That matters for privacy — unlike some document formats, nothing cropped here can be recovered from the download.
Will a cropped PNG keep its transparency?
Yes. If the area you keep contains transparent pixels, they stay transparent in the output, because PNG in and PNG out means the alpha channel is copied with everything else.
Is my photo uploaded while I crop?
No. The image is drawn into your browser’s canvas, you frame the crop there, and the output is produced on your device. Nothing is transmitted at any point.
Why is my downloaded crop larger in pixels than the preview?
The preview is scaled to fit your screen, but the crop is computed against the original image at full resolution. The stamp shows the true output dimensions — those are what you download.
