Image Cropper
Drag a crop box directly on the image to select exactly the area to keep, then export it — entirely inside your browser.
How does this cropper work?
A resizable, draggable selection box overlays the uploaded image. Its position is tracked as a percentage of the image, so once "Apply crop" is pressed, that percentage is mapped back onto the original full-resolution image and drawn onto a canvas at the exact cropped size.
GuideHow to use it
Why cropping happens at full resolution
The crop box is shown on a scaled-down preview of the image for convenience, but its selection is tracked proportionally, not in on-screen pixels. That means the exported crop always matches the original image's full resolution in the selected area, with no quality lost to the preview's smaller display size.
Why it helpsFeatures & benefits
Why this runs entirely in your browser
Cropping uses the browser's own Canvas API to draw the selected region onto a new canvas locally, so the original image never leaves the device — no upload, no server-side processing.
Common uses
Removing unwanted background from a photo, cutting a screenshot down to just the relevant part, or preparing a square crop for a profile picture.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
Yes — the selection box is scaled proportionally back onto the original full-resolution image, so no quality is lost to the smaller on-screen preview.
Yes, drag any of the four corner handles at any time to resize the selection, and drag inside the box to move it.
PNG originals stay PNG with transparency preserved; everything else exports as high-quality JPEG.
Yes — after applying a crop, the original image and selection box are still available, so a different area can be cropped again.
No. All cropping happens locally in your browser. Nothing uploaded here is sent to a server, stored, or shared.
