Fixing a crooked photo
A slightly tilted horizon is one of the most distracting flaws in a photo — and one of the easiest to fix. The angle slider lets you rotate by a fraction of a degree until the horizon, a building edge, or a document margin is perfectly level.
When you rotate by an arbitrary angle, the image's bounding box grows so no corner is ever cut off. The tool fills the new corners with transparency (for PNG/WebP) or a colour you choose — so you can either keep the full frame or crop it afterwards.
How to straighten a photo
- Open your photo. Drag it onto the tool, choose a file, or paste it.
- Nudge the angle. Drag the angle slider, or use the −1°/+1° buttons, until the horizon is level. The preview updates live.
- Choose corners and download. Keep the opened corners transparent or fill them with a colour, then download.
Use a reference line
Pick a line in the photo that should be perfectly horizontal or vertical — the sea horizon, a doorframe, a table edge — and adjust the angle until it lines up. A degree or two is usually all it takes.

Frequently asked questions
How do I straighten a tilted photo?
Open it, then drag the angle slider (or use the −1°/+1° buttons) until the horizon or a vertical edge looks level. Download when it's right.
Will straightening cut off the corners?
No. The canvas grows to fit the rotated image, so nothing is cropped. The new corners are filled with transparency or a colour of your choice.
Does straightening reduce quality?
An angled rotation re-samples the image once, which is normal and barely noticeable. There's no repeated quality loss.
Where is my image processed?
The rotation happens in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
