Cómo usar Enderezar foto de documento
Straighten document photo corrects the perspective of a photographed page using four corner points you supply. Enter the corners in source-image pixels as JSON, in top-left, top-right, bottom-right, bottom-left order, and the tool maps that area to a flat rectangle saved as document-flat.png. It corrects perspective only, not curved or bent pages.
- Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
- Set four corners in source pixels: top-left, top-right, bottom-right, bottom-left (json [[x,y],...]).
- Run straighten document photo, review the output, then use the available copy or download controls.

Preguntas frecuentes
How do I enter the corners to straighten a document photo?
Use a JSON array of four [x,y] pairs in source pixels, ordered top-left, top-right, bottom-right, bottom-left, for example [[40,60],[900,50],[920,1250],[30,1240]]. Every corner must lie inside the image.
Can it flatten a curved book page?
No. The tool applies a perspective transform between four corners, which fixes a flat page photographed at an angle. Pages that bend or curve, such as open book spreads, are not dewarped.
How big is the straightened image?
Width and height come from the longer of each pair of opposite edges you marked. The corrected area must be under 8 megapixels, and corners forming a degenerate shape are rejected.
Where is my input processed?
