Crop images the way you want
Cropping is one of the simplest yet highest-impact image edits you can make: trim the boring edges, fix off-centre subjects, force a thumbnail into a specific shape, or pull a detail crop out of a larger photo. This tool gives you two ways to do it — drag the corners visually, or type exact pixel values when you need millimetre-precise framing.
Visual editor vs pixel editor
The visual editor shows your image full-width with an overlay rectangle. Drag the body to move the crop around, drag any of the eight handles to resize. The crop coordinates are tracked in the original image's pixel space, so what you see in the preview is exactly what you'll get on download — there's no surprise rescaling at the end.
Switch to Pixel mode when you need exact numbers: cropping to a fixed banner size, exporting a slice at known offsets, or matching another image's framing. All four inputs are clamped to the image bounds automatically, so you'll never produce an invalid crop.
Locking an aspect ratio
Pick a ratio from the chip list and the crop rectangle is constrained to that shape from then on. Dragging any handle resizes the rectangle while preserving the locked ratio — drag a corner to scale both dimensions, or an edge to grow the crop symmetrically around its centre line. Switch to Free to drag the crop into any custom shape.
Common picks: 1:1 for Instagram feed posts and profile pictures; 16:9 for YouTube thumbnails, widescreen banners, and presentation slides; 9:16 for Instagram and TikTok stories; 4:5 for vertical portrait posts; 3:2 for classic DSLR prints.
Rule of thirds composition
Toggle the rule-of-thirds grid to overlay two evenly-spaced vertical and horizontal lines. Decades of photography teaching converge on the same advice: place your subject (the eye in a portrait, the horizon in a landscape) along one of those lines, or at one of the four intersections, and the composition immediately feels more balanced. It's a fast trick that beats centring almost every time.
Why crop in the browser
Browser-based cropping has three big advantages over a desktop image editor or a cloud service: it's instant (no upload wait), it's private (your files never leave your device), and it works on every operating system that runs a modern browser — including phones and tablets. The Canvas API used under the hood is the same engine that powers professional web-based design tools, so the result is pixel-perfect even on very large images.
