Crop Image

Crop Image cuts a photo down to just the rectangle you want to keep — a 1:1 square, 16:9 widescreen, 4:3 standard, a tall portrait, or a free-form custom box you draw by hand. It runs entirely in your browser. When you load a picture it's decoded onto an HTML canvas in your device's memory; the selection you draw defines a pixel rectangle that gets copied to a second canvas and re-encoded as PNG or JPEG for download. Nothing is uploaded — there's no server, no upload queue, and no copy of your file sitting in anyone else's storage — which is why it stays fast on a 20-megapixel photo or a weak connection, and why a private headshot or ID scan never leaves your device. You drag a selection box directly over the live preview and pull its corner and edge handles until the framed area is right; drag inside the box to slide the whole thing without resizing. Lock a ratio and the box holds its proportions as you drag, which is the quick way to hit a spec a platform demands: a 1:1 avatar, a 16:9 YouTube thumbnail or slide, a 4:3 product shot, or a 4:5 / 9:16 crop for feeds and stories. It's built for people who reframe images over and over — marketplace sellers squaring up listing photos, bloggers matching a fixed header, teachers dropping images into slide templates, or anyone centering a face without launching Photoshop. A few practical notes: crop a little loose and re-crop rather than cutting tight on the first pass, because pixels outside the box are gone from the export; zoom your browser in if the handles feel fiddly on a high-resolution image; and keep the original file, since cropping only ever removes area and can't rebuild what was trimmed. Because the tool copies the exact pixels you select without rescaling them, the result stays as sharp as that region was in the source — export as PNG for a lossless copy, or JPEG when you want a smaller file.
