Drag a line along something that should be level or upright — a horizon, a table edge, a door frame — and the photo turns to match. Repeat to fine-tune.

Level a photo that came out crooked
A horizon that slopes by a couple of degrees is one of the most common flaws in a photo, and one of the easiest to notice once you see it: the sea looks like it is draining off one side, a building seems to lean, a scanned document sits askew. Rotating in quarter turns cannot fix that. This tool turns the picture by any angle, in steps as fine as a tenth of a degree.
Judging the exact angle by eye is hard, so you do not have to. Drag a line along anything that should be straight — the horizon, the edge of a table, the side of a door — and the tool works out the rotation that makes it level or upright. Rotating exposes empty triangles at the corners; by default the largest crop with the original proportions is taken so none of them remain. Everything happens in your browser.

How to straighten a photo
01
Open the photo
Drop in a JPG, PNG or WebP. A grid is laid over it so a tilt is easy to spot.
02
Draw along the horizon
Drag a line along something that should be level or vertical. The photo turns to match. Draw again to refine it, or nudge the angle in 0.1° steps with the buttons.

The full-resolution photo is rotated and cropped with the same settings and saved in its original format.
quick answers
Straighten image FAQ
How is this different from rotating an image?
Rotating usually turns a picture by 90 degrees at a time, which fixes a photo lying on its side. Straightening turns it by a small, exact angle — often one or two degrees — to level a tilted horizon, and trims the corners that become empty.
How do I find the right angle?
Drag a line along a feature that should be horizontal or vertical, such as the horizon, a shelf or the edge of a building. The tool rotates the photo so that line becomes straight. You can draw again on the result to fine-tune.
Why does the photo get smaller?
Turning a rectangle leaves empty triangles in the corners. To remove them the largest crop with the same proportions as the original is kept, so a small tilt loses only a thin border. Turn cropping off to keep the whole picture with coloured corners instead.
Does rotating reduce quality?
Slightly. Rotating by any angle other than a quarter turn means every pixel is recalculated, which softens fine detail a little. If the result looks soft, run it through the Sharpen Image tool.
The buildings in my photo lean inwards. Will this fix it?
No — that is perspective distortion from tilting the camera upwards, not a rotated photo. Straightening turns the whole picture evenly; use the Perspective Correction tool to make converging lines parallel.
How far can I rotate?
Up to 45 degrees either way, which covers every tilted photo. For larger turns, such as a picture lying on its side, use the Rotate Image tool first.
Is the photo’s metadata kept?
No. The image is redrawn in the browser, so camera details such as EXIF data and location are not carried over. Keep the original if you need them.
Is my photo uploaded?
No. The photo is opened, rotated and saved entirely in your browser, and the result goes straight to your downloads.
