The Image Cropper puts a draggable frame over your photo and cuts out exactly what is inside it. Drag freely, lock the frame to a ratio when the destination needs one, or type exact pixel coordinates when you are matching a spec. The full-resolution crop is applied to the original, not to the preview, and the file never leaves your device.
Cropping is the edit that improves a photograph more often than any other, because most pictures contain something that is not the subject. Drag the frame over the part you want, nudge the edges until the composition sits right, and take the result.
The frame can be dragged freely, locked to a ratio when the destination demands one, or typed in as exact pixel coordinates when you are matching a spec. The readout under the image always shows the true output size, so you know whether a crop has left you enough resolution before you commit to it. Because the work happens on a canvas inside your own browser, a screenshot holding customer data or a photograph of a document is as safe here as it is in your own pictures folder.
Move and resize the frame by hand, or enter X, Y, width and height directly when a spec has to be matched precisely.
Constrain the frame to square, 4:5, 16:9, 9:16 or a custom ratio so the crop cannot drift off shape.
The true output size is shown as you drag, so you know whether the crop leaves enough resolution before you commit.
The preview is scaled to fit your screen but the crop is applied to the original pixels, so nothing is downsampled by accident.
Decoding and cropping both happen on a canvas in your browser, which makes it safe for screenshots holding private data.
Drop a file onto the box or click to choose one. JPEG, PNG, WebP, GIF and SVG all work.
Move the frame by its middle and resize it by any corner. The pixel size updates as you drag.
Choose square, 4:5, 16:9 or 9:16 when the crop has to land on a fixed shape.
Save it as PNG to keep transparency, or JPEG when the file size matters more.
No. Cropping only discards pixels outside the frame; the ones you keep are untouched. Quality is only lost if you then save as JPEG at a low setting, which is a separate choice.
Yes. The X, Y, width and height fields accept exact pixel values, and the frame follows them. That is the reliable way to match a design spec or repeat the same crop twice.
No. The file is decoded and redrawn entirely inside your browser using the canvas API. It never touches a network connection, so it works offline once the page has loaded.
The preview is scaled down to fit the screen, but the crop is applied to the full-resolution original. The pixel readout shows the real output size, not the preview size.
