Crop and straighten any photo entirely in your browser. Drag a crop box over the part you want to keep, level a tilted horizon or a crooked document edge with a fine angle slider, lock an aspect ratio if you need an exact shape, and export the result as PNG, JPG or WebP. Nothing is uploaded — the image is decoded, rotated and cropped on your own device, so it is safe for private scans, ID photos and anything else you would rather not send to a website.
This tool exists because two edits almost always go together. You rarely just crop a photo: the horizon is a degree or two off, the scanned receipt is slightly skewed, or the phone was not quite level. Fixing the angle and then trimming the empty corners in one pass is far faster than bouncing between a rotate tool and a separate cropper, and it keeps the full resolution of your original file.
How it works
When you load an image it is drawn onto an off-screen canvas. The straighten slider rotates that canvas about its centre by the angle you set — anything from −45° to +45° in 0.1° steps — and the preview updates live. Rotation always leaves transparent triangular wedges in the corners, so the crop box sits on top: you drag it to reposition and pull the corner handles to resize, with the area outside dimmed so you can judge the framing. A rule-of-thirds grid inside the box helps you place subjects on natural focal lines.
On export the tool re-renders the rotated image at full resolution (not the scaled-down preview), maps your crop rectangle back to original-pixel coordinates, and copies just that region into a new canvas. PNG keeps it lossless; JPG and WebP add an adjustable quality slider. Because JPG has no transparency, any rotated corners inside the crop are filled white rather than turning black. Your last chosen format, quality and flip settings are remembered in this browser for next time.
Example
You photograph a whiteboard but the shot is tilted about 3° clockwise and includes a chunk of wall. Load it, drag the angle slider to −3.0° until the whiteboard lines are level, switch the aspect ratio to 4:3, and drag the crop box to frame just the board. Click Crop & export, choose JPG at 90%, and download a clean, level, rectangular image — typically a few hundred kilobytes — with no skew and no wall in sight. The whole edit takes about fifteen seconds and never touches the internet.
Common uses: levelling sea or landscape horizons, deskewing scanned documents and receipts, squaring up product shots, cropping avatars to 1:1, and trimming screenshots to a banner ratio.
