About this tool
Straighten photos of documents, whiteboards, paintings and screens that were taken at an angle. Drag the four corners onto the corners of the page; a magnifier helps you place them precisely, and the result is warped into a flat, straight rectangle.
The tool works out the real proportions of the page from its perspective, or you can choose a known shape such as A4, Letter or an ID card. Choose “Full detail” to keep as much resolution as the photo has.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
Questions and answers
How do I scan a document with my phone photo?
Take the photo with the whole page visible, open it here, drag the four corners onto the page corners and download. The page comes out flat and rectangular.
Why are the proportions of my result slightly off?
Automatic proportions assume the photo hasn’t been cropped. If it was, or if you know the paper size, choose it under “Result shape” for an exact result.
Does the tool detect the corners automatically?
No, you place the corners yourself. That way it works on any object, even when the edges are hard to see.
Is Perspective Crop free?
Yes. Every tool on ImgImage is free to use, with no sign-up, no watermark and no limit on how many files you process.
Are my files uploaded anywhere?
No. Your files are processed by your own browser and never leave your device. Nothing you open here is sent to a server.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Large files are processed faster on a computer.
