Crop Image
Drag a box to crop a photo, or lock it to 1:1, 4:3 or 16:9. The box is stored in the pixels of the original image, so the crop keeps the original resolution. The photo never leaves your device.
How to use
- Drop an image onto the box, or press it to choose a file (up to 50 MB).
- Drag the box to move it and drag a corner or edge to resize it. Pick 1:1, 4:3 or 16:9 to lock the shape, or Free to crop any shape. With the box focused, the arrow keys move it.
- Choose PNG, JPEG or WebP and press Crop and download. The size in pixels is shown under the picture.
How it works
The box is stored in the pixels of the original image, not of the smaller preview on screen. When you drag, the movement on screen is scaled up to the real image, so a crop of a 4000 pixel photo keeps all 4000 pixels of detail.
With a ratio locked, the corner opposite to the one you drag stays fixed, and the box grows or shrinks so that width / height stays equal to the ratio, for example 4 / 3. It never leaves the picture.
Phone photos are turned upright using their EXIF orientation before cropping. The cropped area is copied pixel for pixel onto a new canvas and saved. Nothing is uploaded.

FAQ
Is my photo uploaded?
No. The crop is made on your device in this browser tab. There is no upload, no account and no copy kept anywhere else.
Does cropping reduce quality?
The pixels inside the box are copied exactly. PNG output is lossless. JPEG and WebP are saved at a high quality of 92 out of 100, which is hard to tell from the original.
How do I crop on a phone?
Touch and drag inside the box to move it, and drag the square handles to resize it. The handles have a large touch area so you do not need to hit them exactly.
Can I crop to an exact size in pixels?
Not directly. Crop to the shape you want first, then use the Image Resizer to set the exact width and height.
Which ratio should I use?
1:1 suits profile pictures and many social posts, 4:3 matches most camera photos and slides, and 16:9 matches video, YouTube thumbnails and widescreen displays.
