Perspective Correction
Straighten a photo of a document, whiteboard or sign taken at an angle by dragging its four corners. Free.
Perspective Correction flattens anything photographed at an angle, such as a document on a desk, a whiteboard, a poster, a painting or a building sign. Drag the four corners onto the corners of the object and the tool straightens it into a clean rectangle, keeping as much detail as the photo has. Keep the shape as selected or make it A4, Letter or square. The preview updates as you move the corners.

Questions
Can it straighten a page into a PDF?
Download the straightened image, then use JPG to PDF to make a PDF from one or more pages.
Why does my result look stretched?
Choose the right shape: “As selected” estimates it from the corners, but a page photographed at a steep angle is best set to A4 or Letter.
Will it be as sharp as the original?
Parts that were far from the camera have fewer pixels, so they come out a little softer. Taking the photo as straight as possible gives the best result.
Is my photo uploaded?
No. It's processed on your device and never leaves it.
