Crop Image

PNG and WebP-lossless keep every pixel you kept. A JPEG has to go back through the encoder to be saved, so the crop is re-compressed. We write it at quality 92. Worth knowing before you crop the same file five times in a row.

No. Only quarter turns and mirror flips.

Because the orientation tag in the file has already been applied. Many phones store the image sideways with a note attached. The page reads that note and turns the pixels, so the box you drag is the box that gets cut.

There is no limit from us. What decides it is your own computer: a 6000 × 4000 photo is comfortable, and much beyond 100 megapixels a browser canvas starts refusing. If it cannot be done you get a message, not a blank result.

No. There is no server here to upload it to. The page reads the file off your disk and everything happens inside the tab.

Free, 1:1, 4:3, 3:2, 16:9, 9:16 and 3:4. Pick one from the ratio list and the box snaps to that shape around its current centre. If you turn the picture a quarter turn, the ratio turns with it, so 4:3 becomes 3:4. Whole picture resets the box to the full image.

There is no box to type numbers into. You drag the box, and a line under the picture shows the selected size in pixels next to the size of the whole picture. Drag a corner until it reads the width you need. The size of each crop is shown before you export.

Each one keeps its original name with -crop added before the extension, so holiday.jpg comes back as holiday-crop.jpg. The extension follows the format that was actually written. When you export several pictures in one go they arrive together in one zip named cropped-images.zip.
