Perspective Crop Tool
Straighten a tilted photo, like a document shot at an angle. Upload an image, drag the four corner handles to frame the area, then download a flat rectangular crop as PNG.
1. Upload an image
The image never leaves your browser.
2. Drag the four corners
Drag each blue handle to the corner of the area you want to keep. Use your mouse or finger.
3. Preview and download
How to use
- Upload a photo with the file picker above.
- Drag the four blue corner handles so they sit on the corners of the area you want to keep.
- Choose an output shape and width, check the live preview.
- Press the download button to save the straightened crop as a PNG.
Note: Place the handles in order — top left, top right, bottom right, bottom left — for the best result.
Tips
- Works best on documents, whiteboards and posters photographed from an angle.
- Put each handle slightly inside the real corner to avoid black edges.
- A larger output width keeps small text sharper.
