Drag a selection with a rule-of-thirds grid, lock it to any common ratio, straighten a crooked horizon, and export at an exact pixel size.

Free selection plus 1:1, 4:5, 9:16, 16:9, 4:3, 3:4, 3:2 and 7:9. The live readout shows the resulting pixel dimensions as you drag.
Enter an exact width and height and the cropped region is scaled to it on export, which saves running the file through a second tool.
The selection carries a rule-of-thirds overlay, the same guide photographers use to place a subject off-centre rather than dead middle.
Step by step
Drag it onto the box or click to browse. Nothing is uploaded.
Free for anything, or lock to a preset so the selection keeps its proportions while you drag.
Drag inside the box to move it, or grab a corner to resize. The label above shows the exact pixel dimensions.
Open the straighten section and nudge the angle a degree or two to level a horizon.
Pick JPG, PNG or WEBP, set the quality, optionally enter an exact output size, and download.
FAQ
The overlay divides the frame into nine parts. The rule of thirds suggests placing your subject along those lines or at their intersections rather than centring it, which usually produces a more balanced composition.
1:1 for a square social post, 4:5 for a portrait Instagram post, 9:16 for stories and reels, 16:9 for video thumbnails and screens, 4:3 or 3:2 for standard prints, and 7:9 for some portrait formats.
Cropping itself removes pixels rather than degrading them, so what remains keeps its original quality. Quality only drops if you then enlarge the crop to a bigger output size, since that requires interpolation.
It rotates the whole image by a fraction of a degree, which is what a crooked horizon usually needs. Combine it with the crop selection to trim the empty corners that rotation creates.
Yes. Enter a width and height under exact output size and the cropped region is scaled to those dimensions on export. Leave them empty to keep the natural resolution of the selection.
No. The crop is performed by your browser using the canvas element, so the file never leaves your device.
This tool lets you crop an image online with proper control rather than a fixed box. Drag a selection anywhere on the photograph, move it, resize it from any corner, and watch the resulting pixel dimensions update live as you go.
Nine aspect ratios are available alongside free selection: 1:1 for square posts, 4:5 for portrait Instagram, 9:16 for stories and reels, 16:9 for thumbnails and video, 4:3, 3:4, 3:2 and 7:9. When a ratio is locked, resizing keeps the proportion exactly, so the result fits its destination without further adjustment.
The selection carries a rule of thirds grid, which is a genuinely useful composition aid rather than decoration. Placing a subject on one of those lines rather than in the centre of the frame tends to produce a stronger image, and having the guide visible while cropping makes that choice deliberate.
Two extras save a second round trip. A straighten slider rotates the image by fractions of a degree to level a crooked horizon, and an exact output size field scales the cropped region to specific dimensions on export, so cropping and resizing happen in a single operation. Export as JPG, PNG or WEBP with quality control.
Everything runs locally through the browser canvas element, so the image is never uploaded. Continue with the photo editor for colour and exposure, the platform resizer for exact social sizes, or the converter and compressor to reduce the final file size.
